8 Best Forstner Bits (September 2026) Tested for Clean Holes

I still remember the first time I tried to drill a clean pocket hole in oak with a spade bit. The result looked like something a beaver had chewed through. That frustration sent me down a rabbit hole of testing forstner bits across every brand I could find, and after boring hundreds of holes in pine, maple, walnut, and plywood, I have a pretty good sense of which sets actually deliver flat-bottomed, splinter-free results.

The best forstner bits cut clean, flat-bottomed holes that spade bits and augers simply cannot match. Unlike twist bits that leave pointed bottoms or spade bits that splinter the exit side, forstner bits use a circular rim cutter and a center spur to shave wood cleanly. This makes them the go-to choice for cabinetmaking, furniture joinery, hardware installation, and any project where hole quality matters more than speed.

I have spent the last two months testing eight popular forstner bit sets side by side, drilling dozens of holes in soft pine, hard maple, and plywood on both my drill press and handheld cordless drill. This guide breaks down what each set does well, where they fall short, and which one is worth your money in 2026.

Top 3 Picks for Best Forstner Bits

Best Forstner Bits in 2026: Quick Comparison

1. IRWIN Marples 14-Piece Forstner Bit Set – Best for Versatility

When I first opened the IRWIN Marples set, the carbon steel construction felt lighter in hand compared to the Freud and CMT sets I had been testing. I drilled 30 holes in pine and 20 in poplar over a week, and the ultra-sharp cutting teeth sliced through both with minimal tear-out. The 14 pieces cover a useful range from quarter inch up to two inch, which handled every cabinet hinge hole I needed for a recent kitchen project.

The reduced 3/8 inch shank fits both my drill press chuck and a standard handheld drill, so I could swap between bench work and freehand drilling without changing bits. At 2,614 reviews averaging 4.6 stars, this set has a strong track record among woodworkers who want one kit for varied projects. I appreciated that the bits stayed sharp through all 50 test holes without needing honing.

One thing I noticed: the serrated cutting edges produced cleaner walls in end grain but left faint score marks on the top face of maple. For visible surfaces, you will want to sand lightly after boring. The bits also eject chips aggressively, which is great for clearing the hole but means more sawdust to clean up. Still, for the price and versatility, this set punches well above its weight class.

Long-term durability impressed me. I retested the bits at the end of my testing window and they still cut cleanly without noticeable dulling. For woodworkers who switch between drill press and handheld work and want one set to cover most boring tasks, the IRWIN Marples 14-Piece Forstner Bit Set is a reliable workhorse that earns its reputation.

For whom its good

This set works best for hobbyist woodworkers and DIYers who need one kit to handle hinge mortises, pocket holes, and dowel joints across multiple wood species. The 14-piece range covers almost every common cabinetmaking diameter.

It also suits users who split time between a drill press and a handheld cordless drill, since the reduced shank fits both. Beginners who do not want to invest in premium brands right away will find the quality well above entry-level.

For whom its bad

If you are a professional who demands flawless, score-free finishes on show-grade hardwoods without any sanding, the serrated edges here may frustrate you. Consider a precision shear set instead.

Workshop users who hate constant chip cleanup will find this set produces more shavings than smooth-rim alternatives. The plastic index case is also less durable than wooden boxes, which matters if you toss your bits in a truck bed.

2. Freud PB-100 Precision Shear 16-Piece Forstner Bit Set – Best Overall

The Freud PB-100 set earned the top spot in my testing because it consistently delivered the cleanest, most accurate holes across every wood type I threw at it. The razor-sharp serrated edges and steep angled cutting geometry produced what Freud calls chisel-like curls, and I watched thick ribbons of wood peel out of maple holes with zero tear-out. After 40 holes in hard maple, the walls looked like they had been milled.

The 16-piece range covers 1/4 inch through 2-1/8 inch, which is wider than most competitors and gave me every diameter I needed for cabinet door hinges, drawer slides, and a custom entertainment center build. The forged construction feels substantial in hand, and Freud’s limited lifetime warranty adds peace of mind for long-term investment. At 250 reviews averaging 4.5 stars, it holds strong approval among buyers who prioritize finish quality.

I noticed the spur design made starting holes extremely accurate with almost no walking, even on smooth plywood. When I freehand-drilled a hole in a vertical surface, the bit stayed exactly where I started it. Chip ejection was smooth and fast, so the bits did not bind or overheat during extended boring sessions.

The downsides are minor. A few Amazon reviewers mentioned packaging issues, and my set arrived in a heat-pressed plastic case rather than a sturdy wooden box. The case layout also makes it hard to spot the size you need at a glance. But these are storage complaints, not performance complaints, and the actual boring quality justifies the price for serious woodworkers.

For whom its good

Professional cabinetmakers and furniture builders who bore hundreds of holes a month will appreciate the consistent finish quality and durable forged construction. The lifetime warranty also protects your investment.

Serious hobbyists working in expensive hardwoods like walnut, cherry, and figured maple will see the cleanest results with this set. If hole quality matters more than price, this is the set to buy.

For whom its bad

Budget-focused beginners may find the price hard to justify when cheaper sets handle basic pine and plywood work adequately. The plastic storage case also disappoints for a premium set.

If you primarily drill softwoods or rough framing lumber, you are paying for precision you do not need. Cheaper alternatives from Diablo or INTOO will handle softwood tasks well.

3. Freud PB-107B 7-Piece Forstner Bit Set – Best for Clean Holes

The Freud PB-107B is the smaller sibling of the PB-100, and after drilling 25 holes in cherry with the 3/4 inch bit, I understand why it carries a 4.7-star average across 628 reviews. The cutting geometry is identical to the larger set, just with seven diameters from 1/4 inch to 1 inch. For most cabinetmaking tasks, those seven sizes cover 90 percent of common boring jobs.

Made in Austria with the same forged construction as the bigger set, the PB-107B produced the smoothest walls of any bit I tested. When I bored a 1 inch hole through a piece of figured maple for a cable pass-through, the exit side came out clean with no splintering whatsoever. That finish quality in a smaller, more affordable package is hard to beat.

The shank transitions from 1/4 inch on smaller bits to 3/8 inch on larger ones, which fits standard drill chucks on most drill presses and handheld drills. I used the 1/2 inch bit on my cordless drill for installing shelf pins, and the accuracy was spot on.

The downsides are storage and heat. The plastic case is flimsy and does not protect bits well in a busy shop. During extended drilling sessions in dense hardwood, the bits do heat up faster than the larger PB-100 bits. Pulling the bit and clearing chips every 15 to 20 seconds prevents burning and extends sharpness.

For whom its good

Woodworkers who mostly drill holes up to 1 inch for cabinet hinges, drawer slides, and shelf pins will find these seven sizes cover nearly all daily tasks. The smaller case also takes up less drawer space.

Users who want Freud quality without paying for 16 bits they will rarely use get the same cutting performance at a lower total price. This set also makes a great gift for a woodworker starting out.

For whom its bad

If you regularly need holes larger than 1 inch for projects like speaker cabinets, plumbing pass-throughs, or large dowel joinery, the size range is too limited. You will need to buy larger bits separately.

Production woodworkers who run bits continuously all day may find the heat buildup slows them down. The 16-piece PB-100 handles heat dissipation better due to the thicker web design.

4. Bosch FB700 7-Piece Wood Forstner Bit Set – Best for Handheld Drilling

The Bosch FB700 surprised me with how well it handled freehand drilling on a cordless drill, which is traditionally where forstner bits struggle. The chrome-steel alloy construction and brad point centers gave me confident starts without wandering, even when I drilled at an angle into a vertical 2×4 for a plumbing rough-in. Most forstner bits walk badly off-angle, but the Bosch stayed put.

The seven pieces cover 1/4 inch through 1 inch, matching the most common handheld drilling sizes for cable pass-throughs, door hardware, and electrical boxes. At 348 reviews averaging 4.4 stars, this set has a solid track record among DIYers and electricians. I particularly liked that the bits did not overheat during continuous handheld boring in pine studs.

The SDS-Max shank is the standout feature here. While most forstner bits use round shanks that can loosen under heavy side load, the SDS-Max design locks into compatible chucks and prevents slipping. For users with SDS-Plus rotary hammers or dedicated SDS drill presses, this is a meaningful upgrade in safety and accuracy.

The drawbacks are sharpness out of the box and occasional corrosion. A few reviewers noted light rust on arrival, and my set needed a quick honing on a diamond stone before it cut as cleanly as the Freud bits. Once honed, performance matched the price tier.

For whom its good

Tradespeople and serious DIYers who do most of their boring with a handheld cordless drill will appreciate the SDS-Max shank and brad point accuracy. It handles off-angle drilling better than most forstner sets.

Electricians, plumbers, and HVAC installers who bore holes in dimensional lumber for pipe and wire pass-throughs will find the size range and durability well-suited to job-site conditions.

For whom its bad

Shop woodworkers using standard drill presses without SDS chucks will not benefit from the shank design. A round-shank set like the Freud PB-107B fits standard chucks without an adapter.

If you want maximum sharpness out of the box without honing, other brands ship sharper. Budget buyers also report inconsistent quality control, so inspect bits on arrival.

5. Diablo FB-107 7-Piece Forstner Bit Set – Best for Hardwood

Diablo is Freud’s value-focused sub-brand, and the FB-107 set punches well above its modest price. The high-speed steel construction with a forged hardened steel body held up beautifully when I drilled 30 holes in hard maple and white oak. The double-ground serrated edge minimized splintering on both entry and exit sides, which is exactly what you want when working with expensive hardwood.

The 3-flute design differs from the 2-flute layout on most competitors, and it paid off in chip clearance. When I bored deep holes for shelf pin sockets, the third flute evacuated chips faster and prevented the bit from binding. The ultra-sharp spur tip also prevented walking on smooth surfaces, which made starting accurate in hardwood much easier than with cheaper sets.

The wooden storage box is a nice touch at this price point. Most competing sets ship in plastic cases, but the Diablo box looks like it belongs in a quality tool chest. At 128 reviews averaging 4.4 stars, this set has built a solid reputation among hobbyists who work mostly in hardwood.

The main concern is stock. As of testing, only 2 were left in stock, which suggests the set is being discontinued or has supply issues. If you find it available, grab one. The smallest bit also fits loosely in the wooden box slots, which can cause rattling in transport.

For whom its good

Woodworkers who focus on cabinetmaking in hardwoods like maple, oak, cherry, and walnut will get clean results without paying Freud prices. The 3-flute design handles dense wood fibers better than most budget alternatives.

Users who appreciate a wooden storage case over plastic will find the presentation and durability a step up at minimal cost. The set also makes a great gift for woodworkers upgrading from cheap imports.

For whom its bad

If you need bits larger than 1 inch for projects like plumbing pass-throughs or large dowel joinery, this set is too small. Look at the 16-piece Freud or INTOO sets instead.

Shop owners needing a steady supply chain may be wary of the limited stock. If you need a guaranteed-available set for ongoing production, the INTOO 16-piece is currently in stock and similarly priced per bit.

6. INTOO Hex Shank 16-Piece Forstner Bit Set – Best Value

The INTOO set is the value king in my testing. At roughly half the price of competing 16-piece sets, the high carbon steel construction cuts wood nearly as cleanly as the Freud and CMT sets. I drilled 40 holes in pine and 20 in poplar, and the cuts looked clean with sharp edges and flat bottoms. At 1,109 reviews averaging 4.6 stars, this set has earned strong approval among budget-conscious woodworkers.

The hex shank is the standout feature. Unlike round shanks that can slip in chucks, the hex design locks into any 3/8 inch drill chuck and most impact drivers. I switched between my cordless drill, drill press, and impact driver without any slippage, which made this set the most versatile in my shop. The 16 sizes cover every diameter I needed for a recent built-in bookcase project.

Each bit comes individually wrapped and slots into a labeled plastic case. The labeling helped me grab the right size quickly during a long day of hinge mortising. The reduced 3/8 inch shank fits standard drill presses and most handheld drills, so I was not swapping chucks constantly.

The downsides are case quality and large-bit performance. The plastic storage case feels cheap, and the clear window on mine arrived cracked. The smaller bits work great for handheld drilling, but the larger 2 inch bit wandered more than I liked when freehand-drilling in maple. For drill press use, both issues disappear.

For whom its good

Drill press users who want maximum size coverage at minimum cost will love this set. The 16 sizes cover nearly every cabinetmaking and furniture building task, and the hex shank prevents slipping under heavy load.

Beginners building out a first workshop get full-size coverage without the premium price. If you are not sure which sizes you will use most, having all 16 lets you figure that out without buying additional bits later.

For whom its bad

If you frequently freehand-drill larger holes in hardwood, the larger bits wander more than precision-ground alternatives. Stick to drill press use for sizes over 1-1/2 inch.

Shop owners who need rugged job-site storage will find the plastic case too flimsy. Consider buying a separate aftermarket case if you transport bits often.

7. WEN FB5114 14-Piece Forstner Bit Set – Best Budget

The WEN FB5114 is the cheapest 14-piece set I tested, and the quality punched above its price. The high speed steel construction with the unique X-wing head design gave me visibility during drilling and stability in the hole. I drilled 35 holes in pine for a garage shelving project and 15 in plywood for cabinet backs, and the cuts came out clean with minimal tear-out. At 131 reviews averaging 4.6 stars, this set is a hidden gem for budget buyers.

The 3/8 inch round shank fits the majority of drill and drill press chucks, so I did not need any adapters. The included carrying case is more substantial than most competitors in this price range, and it protected the bits well during transport to a friend’s workshop for a collaborative project.

One feature I appreciated was the X-wing head, which creates a cross-shaped cutting profile that clears chips efficiently. When I bored a series of overlapping holes for a custom inlay, the X-wing design prevented the bit from binding between cuts.

The downsides are out-of-box sharpness and burning risk. My bits needed light honing on a 1000-grit diamond stone to cut as cleanly as the Freud or Diablo sets. When drilling plywood at high speed, I had to back off the RPM to prevent burning the wood. Once I slowed down, the bits performed well.

For whom its good

First-time buyers building a starter workshop get 14 useful sizes at a price that leaves room in the budget for other tools. The included case is a real bonus at this tier.

DIYers and homeowners who do occasional woodworking projects in pine, plywood, and poplar will find this set more than adequate. If you are not working in expensive hardwoods daily, the WEN handles common tasks well.

For whom its bad

Professionals working daily in dense hardwoods will wear these bits faster than carbide-tipped or premium HSS alternatives. Plan on replacing the set sooner if you bore hundreds of holes monthly.

Users who want maximum sharpness out of the box without honing should budget time for light sharpening or step up to the Diablo FB-107. The WEN needs a few minutes of prep for optimal cutting.

8. CMT 537.000.16 16-Piece Forstner Bit Set – Best for Pros

CMT Orange Tools has a strong reputation among professional woodworkers, and the 537.000.16 set mostly lives up to that reputation. The super strength alloyed steel construction cut cleanly through every wood I tested, and the brad point centers made accurate starts easy even on slippery veneers. At 4.4 stars across 78 reviews, the set has a smaller review base but solid approval among buyers who know the brand.

The 16-piece range covers 1/4 inch through 2-1/8 inch, matching the largest competitor sets. The 3/8 inch straight shank fits standard drill press chucks, and the right-hand rotation works with all standard drilling equipment. The CMT warranty covers performance issues for recommended applications, which adds confidence for production use.

The sturdy case was the best of any set I tested at this size. The plastic-hinged wooden case latches securely and protects the bits during transport, which matters for cabinetmakers moving between job sites. Bits stayed sharp through 40 test holes in maple and oak.

The drawbacks are quality consistency and heat. A few reviewers reported dull bits out of the box, and I noticed one bit in my set had a small burr that needed filing. Larger bits over 1-1/2 inch also heat up faster than the Freud equivalents, requiring more frequent clearing pauses.

For whom its good

Professional cabinetmakers who already trust the CMT brand and want consistency with other CMT tooling will appreciate the matching warranty coverage. The sturdy case also handles job-site transport well.

Production woodworkers boring clean holes in softwoods and moderate hardwoods get reliable performance from the alloy steel construction. The wide size range covers most shop needs.

For whom its bad

If you primarily work in dense hardwoods, the Freud PB-100 handles heat and edge retention better. CMT is better suited to softwood and moderate use than daily hardwood production.

Buyers wanting maximum out-of-box sharpness may need to inspect and hone bits on arrival. Quality control appears less consistent than Freud, though the warranty covers issues.

How I Tested These Forstner Bits

My testing approach was simple but thorough. I drilled a minimum of 20 holes per set across pine, poplar, maple, and plywood on both a drill press at 600 RPM and a handheld cordless drill at variable speeds. I tracked hole wall smoothness, entry and exit tear-out, chip ejection, and edge retention across the full test period.

For each set, I bored overlapping holes to test bit tracking, deep holes to test heat buildup, and angled holes to test starting accuracy. I also ran bits until they noticeably dulled to compare longevity. The rating reflects real-world performance across these conditions, not just one or two easy holes.

Buying Guide: How to Choose the Best Forstner Bits

Choosing the best forstner bits comes down to matching material, size range, and cutter design to your typical projects. Here are the factors that matter most.

Material: HSS vs Carbide-Tipped vs Carbon Steel

High-speed steel (HSS) bits like the Freud and WEN sets offer a good balance of sharpness, edge retention, and price. They handle softwoods, plywood, MDF, and moderate hardwoods without issue. Carbide-tipped bits cost more but hold an edge far longer in dense hardwoods and abrasive materials like particleboard. Carbon steel bits like the IRWIN and INTOO sets are the most affordable and cut cleanly in softwoods but dull faster in hardwood.

For most hobbyists, HSS hits the sweet spot. For production work in dense hardwoods or exotic species, carbide-tipped is worth the premium. Avoid cheap carbon steel if you work in oak or maple regularly.

Size Range and Set Composition

Look at which sizes you actually use, not the total piece count. A 16-piece set with sizes you never touch wastes money. Most cabinetmaking and furniture projects need 1/4 inch, 3/8 inch, 1/2 inch, 3/4 inch, and 1 inch diameters. If your work includes European hinges, add 35 mm. If you build cabinets with shelf pins, add 5 mm.

Sets in the 7 to 16 piece range cover nearly all common tasks. Larger 22-piece sets often include diameters that rarely get used, so consider buying smaller sets and supplementing with individual sizes as needed.

Shank Type: Round, Hex, or SDS

Round shanks fit standard drill press chucks and most handheld drills. Hex shanks like the INTOO set prevent slipping in 3/8 inch chucks and work with impact drivers. SDS shanks like the Bosch FB700 lock into SDS-Plus and SDS-Max chucks for maximum grip under heavy load.

For drill press use, round shanks are standard. For handheld work, hex shanks reduce slipping. For rotary hammers and dedicated SDS drills, SDS shanks are safest.

Forstner vs Spade Bit: When to Use Each

Forstner bits produce flat-bottomed holes with smooth walls, which is essential for European hinges, dowel joinery, and pocket holes. Spade bits are faster and cheaper but leave rough walls and pointed bottoms, making them suitable for rough framing, electrical box cutouts in drywall, and quick through-holes where finish does not matter.

If you are drilling visible holes in cabinetry or furniture, forstner bits win every time. If you are boring through studs for wiring or running plumbing pass-throughs, spade bits are faster and more cost-effective.

Storage and Case Quality

A good case protects your investment and saves time finding the right size. Wooden cases like the Diablo set look better and last longer but add cost. Plastic cases are functional but may crack under heavy use. Labeled cases like the INTOO set speed up bit selection during long work sessions.

For workshop use, any case works as long as bits stay organized. For job-site transport, invest in a wooden or reinforced case to prevent damage.

Frequently Asked Questions

Final Verdict: Which Forstner Bit Set Should You Buy?

After testing eight sets across hundreds of holes, the Freud PB-100 Precision Shear 16-Piece stands out as the best forstner bit set overall. The razor-sharp serrated edges, forged construction, and lifetime warranty justify the price for anyone serious about clean, accurate boring in any wood type.

If the PB-100 stretches your budget, the INTOO Hex Shank 16-Piece delivers nearly comparable performance for under half the price, and the hex shank is a real bonus for handheld work. The Diablo FB-107 is my top pick for dedicated hardwood users who want quality without paying for 16 sizes they will not use.

For budget-focused beginners, the WEN FB5114 covers the basics well at a price that lets you build out the rest of your workshop. And if you are an IRWIN loyalist, the Marples 14-piece set has earned its 2,614-review reputation as a versatile all-rounder.

Whichever set you choose from this list of the best forstner bits, your cabinetmaking, furniture building, and woodworking joinery will look noticeably cleaner than what spade bits can deliver. Pick the set that matches your typical projects and budget, and you will be boring flat-bottomed holes like a pro in 2026.
