DeWalt 7/16" Pilot Point drill bit

A 7/16-inch hole is big enough to expose the shortcomings of a mediocre bit. That’s why I pay attention to features that help with accuracy, torque, and durability at this diameter. After running this DeWalt pilot‑point bit through a mix of wood, mild steel, and plastics in both a drill press and a 1/2-inch cordless drill, I came away with a clear sense of where it excels—and where you’ll want to set expectations.

Why a pilot point matters at this size

At 7/16, a standard chisel‑edge bit can skitter on smooth or curved surfaces and leave you fighting to keep the hole on layout. The pilot point on this bit changes that dynamic. It grabs on contact and establishes the center before the main cutting edges engage, which reduces walking and shortens the time you spend coaxing a hole to start. It’s especially helpful in hand‑held drilling where you don’t have the rigidity of a drill press to compensate for a wandering tip.

Test setup and materials

I used the bit to:
- Bore through 2x SPF studs, plywood, and a piece of white oak
- Drill 1/8-inch and 1/4-inch mild-steel flat bar and angle
- Open holes in aluminum sheet and PVC
- Spot‑face a few hardware locations where a washer needed to sit flat

Most holes were done with a 1/2-inch chuck cordless drill in low gear, with a few precision starts on a benchtop drill press. Cutting fluid was used on steel, and I backed the bit out periodically on deeper holes to clear chips.

Starting accuracy and walking

The pilot point does what it’s supposed to do. In wood and aluminum, I was able to place holes right on layout without center punching. On painted and slightly curved steel, I still prefer a light center punch—it’s just good practice at this diameter—but the bit started cleanly even when I intentionally skipped that step. Compared to a standard jobber bit, I saw less skating and less initial chatter, especially noticeable in hand drilling.

One caveat: the pilot point is not a brad point. In hardwood, it keeps the tip from walking, but it won’t give you the laser‑clean entry and exit you get from a dedicated brad‑point wood bit. With a backer board, exits were respectably clean; without one, hardwood chipped a bit at 7/16, as expected.

Speed, feed, and chip evacuation

Large diameter holes benefit from conservative RPM and steady pressure. Here are practical ranges that worked well for me:
- Mild steel: roughly 500–800 RPM with cutting fluid
- Aluminum: around 1,200–1,700 RPM, keep chips flowing
- Wood: low gear on a cordless drill (about 500–900 RPM) keeps tear‑out down and heat in check

The flutes clear chips efficiently for jobber length, but you still need to peck on deeper holes—drill a bit, back out to clear chips, repeat. Doing so drops heat, prevents binding, and extends edge life. When I tried to push continuously through 1/4-inch steel plate without pecking, heat built up and the finish dulled faster than necessary.

Hole quality across materials

• Wood (SPF and oak): Entries were clean with minimal fuzzing. Exits were fair to good with a backer. The bit tracks straight and produces a round hole. For visible cabinetry-grade work, a brad point still has the edge; for framing and general carpentry, this is absolutely sufficient.
• Mild steel: With fluid and proper RPM, the bit produces a smooth, round hole with manageable burr on the exit. Deburring with a countersink or file was quick. The pilot point reduces the tendency to “skate” at the start and makes up for small alignment errors in hand drilling.
• Aluminum: Very clean holes, excellent chip evacuation. Keep the feed consistent to avoid galling. A trace of wax or light oil helps.
• Plastics (PVC and acrylic offcuts): The tip engages without grabbing. Slow RPM and light pressure prevent melting. Holes were clean with minimal breakout.

Shank grip and compatibility

The no‑spin shank kept the bit locked in both keyed and keyless chucks. I didn’t experience slippage under heavy feed in steel, which is what you want at this torque level. Remember that a 7/16 bit requires a 1/2-inch chuck; 3/8-inch chucks won’t accept it. If you’re planning to run it in a drill press, the jobber length is convenient: the overall length is about 5-19/32 inches with a working length around 4-1/16 inches, which gives you decent reach without the chatter that can come from extra‑long “aircraft” bits.

Durability and edge life

The tapered web contributes to stiffness and reduces the risk of catastrophic breakage. Frankly, breakage is a bigger concern on small diameters than on a robust 7/16, but the added rigidity is still welcome when the bit is partially buried and you’re levering a hand drill to stay on line.

Edge life was solid in wood and aluminum. In mild steel, after a run of holes in 1/4-inch plate, I noticed the expected slowdown in bite—nothing unusual for a general‑purpose bit. With cutting fluid, appropriate RPM, and pecking cycles, the sharpness held up well across a reasonable weekend’s workload.

One practical note: pilot points are trickier to sharpen at home than standard split‑point bits. If you rely on this bit heavily in metal, plan to send it out for sharpening or treat it as a consumable and replace when dull. For occasional use, it should last a long time with proper technique.

Limitations and best practices

• Not for stainless or hardened steels: It will get the job done in a pinch with patience, but for frequent stainless work, a cobalt bit is a better choice.
• Not a woodworking specialist: It does well in wood, but if crisp tear‑out‑free holes are the priority, grab a brad point.
• Keep it cool: Use cutting fluid in ferrous metals, peck to clear chips, and avoid high RPMs. Blueing is a sign you’re going too fast.
• Secure the work: At this diameter, a loose workpiece will grab and spin. Clamp it.
• Consider a pilot hole in thick steel: A small pilot (e.g., 1/8 to 3/16) shortens the heavy cutting time and improves accuracy, even with a pilot point.

Markings and small usability touches

The size marking above the shank is surprisingly handy. Bits get scuffed and coated in cutting fluid, and markings on the shank shoulder tend to stay readable. It’s a small touch that speeds up bit changes on a busy bench.

Value

As a single, large‑diameter bit, this isn’t the cheapest item in your box. The question is whether the pilot‑point convenience and reliable chuck grip are worth paying a bit more than a generic jobber. If you routinely start large holes by hand on finished surfaces, doors, or strut, the time saved and fewer do‑overs will justify it. If you mostly drill on a press with a center drill and vise, you’ll see less advantage versus a standard bit.

There’s a 30‑day money‑back window, which is nice peace of mind if you’re unsure how it fits your workflow. For long‑term heavy steel work, I’d budget for a cobalt alternative, but for general shop and site drilling across wood, metals, and plastics, this bit hits the right balance.

Bottom line

I recommend this DeWalt pilot‑point bit for anyone who needs accurate starts and dependable grip in a 7/16-inch size, especially for hand drilling across mixed materials. It starts cleanly, resists walking, holds in the chuck under load, and produces tidy holes when you mind your speeds and use cutting fluid in steel. It’s not a specialist wood bit and it’s not the warrior you want for frequent stainless, but as a general‑purpose, jobber‑length workhorse, it earns a place in the kit. The price reflects the convenience and consistency; if those matter to you—and at this size they often do—you’ll get good value out of it.
