DeWalt #10 Replacement Drill Bits (1/8") - 2 Pack

My box of countersink pilots is a graveyard of snapped 1/8-inch bits. That’s why I’m always on the lookout for replacements that start clean, hold up in hardwood, and don’t force me to buy a whole new countersink every time the pilot gives up. The DW2722 bits fit neatly into that niche: a two-pack of #10 (1/8") replacement drill bits with included countersinks, purpose-built for wood, with split-point tips and a black oxide finish.

What’s in the pack

You get two #10, 1/8-inch bits paired with countersinks. The stated working length is 1.9 inches, with an overall length around 5-3/4 inches. The design is geared for wood, and the split-point tip is meant to reduce walking when you first touch down. The black oxide coating is there to ward off corrosion and cut down on friction.

The big idea here is sustainability and convenience: the countersinks are included, so going forward you’re just replacing the bits as they wear out or break rather than tossing the entire countersink assembly. If you use #10 flat-head wood screws regularly, that’s a very practical approach.

Design and build

The split-point geometry is the first thing I noticed in use. It bites immediately and centers itself better than a standard chisel-tip pilot. That translates into fewer skating marks on finished faces and more predictable alignment for hinge work and hardware installation.

The black oxide finish isn’t magic, but it does make a difference in two ways. First, it helps with chip flow and reduces the sudden “grab” you sometimes feel in dense hardwood. Second, it slows down rust if your bits live in a jobsite box or a damp basement. It’s not a substitute for premium coatings or carbide in abusive materials, but for wood it’s a sensible choice.

The countersink profile matches common flat-head wood screws well. On my test pieces, the chamfer seated screws flush with a clean edge, without the fuzzy halo you can get from dull or poorly ground countersinks. The assembly runs true in a standard drill/driver chuck. I didn’t notice noticeable runout beyond what my drill contributes.

Setup and compatibility

There’s nothing exotic about getting these going. Chuck one up and you’re drilling. The overall length is on the longer side for a pilot/countersink combo, which helps visibility and clearance when you’re working on face frames or trim. In tight cabinetry or inside cases, you will feel that extra length; plan your approach and consider a right-angle attachment if needed.

The bit diameter is spot-on for #10 wood screws in most species. If you prefer to undersize pilots in softwoods for extra bite, you might keep a 7/64" pilot handy for those cases. For general woodworking and mixed species, the 1/8" pilot is a safe, hardware-friendly default.

In the wood: performance

I ran the DW2722 bits through a mix of pine, poplar, birch ply, white oak, and a few sticks of pressure-treated southern yellow pine. Here’s how they behaved:

• Starting and tracking: The split-point does what it promises. Starts are controlled, even on slick prefinished ply. In oak and maple, the initial bite is predictable and reduces the tendency to skate on end grain.
• Chip evacuation: In softwood and plywood, chips cleared well at moderate drill speeds (1,200–1,800 RPM on a cordless drill). In dense hardwoods, pecking the hole helps keep the bit cutting cool and clean.
• Countersink quality: The included countersink leaves a clean chamfer. In oak, slowing down for the final half-turn made the difference between crisp and slightly burnished edges. Screws seated flush without chatter marks.
• Tear-out control: Backing the workpiece or easing the feed as the bit exits helps prevent blowout on the backside. That’s typical for 1/8-inch pilots; the DW2722 is no different.

In MDF and other resin-heavy sheet goods, I noticed the pilot edge soften sooner than in hardwoods. That’s expected; MDF is abrasive. After a session of shelf-pin pilots and hinge holes, I cleaned the edges up with a diamond card and was back to clean drilling. If you live in MDF, plan on more frequent touch-ups or a dedicated MDF set.

Durability and heat

Black oxide isn’t a wear-resistant coating in the way that TiN or TiCN are, but it does handle heat cycles decently. With steady, moderate feed pressure, the bits stayed sharp through a good run of cabinet installs and trim-out. I didn’t experience tip blueing or temper loss, even after longer runs in oak. The 1/8-inch diameter is inherently fragile under side load, so the usual caveats apply: let the bit cut, avoid prying in the hole, and don’t hammer on the countersink to hog material.

The real durability win is system-level: since the countersink is included and reusable, a snapped pilot isn’t a costly mistake. You swap the bit and get back to work. That’s both economical and less wasteful.

Accuracy and finish quality

For joinery and hardware prep, repeatability matters more than micrometer precision. With these bits, hole size and countersink depth were consistent across a batch, assuming I held the drill square and kept a steady hand. The chamfer profile matched typical #10 flat-head screws; heads sat flush without needing a second pass, and the edge of the countersink cut cleanly enough to leave finished faces ready for paint or clear coat.

If you need absolute precision on countersink depth—say, for exposed hardware on high-end furniture—you’ll still want a depth stop or a drill guide. The DW2722 doesn’t change the fact that handheld countersinking is only as consistent as your technique.

Where they shine and where they don’t

Strengths:
- Fast, controlled starts thanks to the split-point tip
- Clean, predictable countersinks for #10 flat-head screws
- Black oxide finish resists rust and manages heat reasonably well
- System makes sense: replace bits, not the whole countersink assembly
- Practical working length for most cabinetry, trim, and general carpentry

Limitations:
- Not intended for metal; performance there is poor compared to metal-specific bits
- MDF and other abrasive composites will dull the pilots faster
- Long overall length can be awkward in cramped corners
- If you need other screw sizes regularly, you’ll want additional pilots and countersinks to match

Tips for best results

• Use moderate RPM and pressure in hardwoods; let the split-point do the work.
• Peck to clear chips in deep holes and reduce heat buildup.
• In MDF, lighten up and sharpen more often, or wax the pilot to reduce friction.
• Back up your work to prevent backside blowout, especially on veneered plywood.
• Stop short and check screw fit; you can always widen the countersink with a light kiss.

Value and use cases

The value proposition is straightforward: consistent wood performance, included countersinks, and a replace-the-pilot workflow that cuts down on waste. For the shop that installs a lot of hardware, builds face frames, or hangs doors and trim, having a couple of dedicated #10 pilots ready to go is almost mandatory. The two-pack adds redundancy; when one goes dull or snaps, you’re not dead in the water.

If you’re decking an entire porch or spending your days in composites, there are more specialized options. For general woodworking and carpentry in real wood, though, these hit the right balance of cost, convenience, and cut quality.

Recommendation

I recommend the DW2722 bits for woodworkers and carpenters who routinely drive #10 flat-head screws and want a clean, reliable pilot-and-countersink in one. The split-point starts are trustworthy, the countersink profile is clean, and the black oxide finish holds up well in typical shop and site conditions. Most importantly, the included countersinks mean future maintenance is easy and economical—you replace the pilot, not the whole unit.

They’re not a universal answer. If you need metal-capable bits, ultra-long life in MDF, or ultra-compact reach, look elsewhere. But for day-in, day-out woodwork, these are a sensible, dependable choice that keep the focus on the task and not on your bit drawer.
