The DEWALT D180040 4-inch hole saw is a bi-metal deep-cut saw built for fast, durable drilling. Its double-tooth design strengthens each tooth for longer life, while the increased high-speed steel height improves durability. The thick, hardened backing plate prevents thread stripping. This hole saw is ideal for cutting through wood, metal, and plastic for electrical, plumbing, and construction work.
This 4-inch bi-metal hole saw uses precise tooth geometry to remove material quicker and stay sharp longer. The deep-cut style allows you to cut through 2x material in a single pass, saving time on the job.
The double-tooth design distributes cutting pressure and reduces chattering. Sharper tooth geometry cuts aggressively without overloading the drill.
With a deep-cut profile, you can bore through thicker stacks of wood or metal without stopping to clear chips. It's a great choice for installing large-diameter conduit or piping.
The D180040 fits standard 1/2-inch hex arbors, so you can use your existing arbor or pick up a DEWALT DW1622. Always use pilot bits that match the arbor.

For large openings like electrical boxes, conduits, or door locks, a 4-inch bi-metal hole saw is a versatile choice. The deep-cut design means you can work through thicker materials without stopping.
The high-speed steel teeth stay sharp, the alloy body handles high torque, and the double-tooth design reduces vibration for cleaner holes.
With a standard 1/2-inch hex arbor, this hole saw mounts on most corded and cordless drills. Just add the correct pilot bit and you're ready to cut.
Run at moderate speed and apply steady pressure. When cutting metal, use cutting fluid to keep the teeth cool and prevent premature dulling.
Uses a standard 1/2-inch hex arbor, such as DEWALT DW1622.

Single 4-inch hole saw.

Sharp and fast.
I used it to drill holes for deadbolts. It went through wood like butter. The teeth are still sharp after many uses. Definitely worth it.
It's a good bit, but I found the depth is a little shallow. For a 4-inch hole, I needed to go slow. It works fine.
Cuts through 2x4s easily.
I've used this on many jobs. It's still cutting well. The double tooth design seems to help. It doesn't bind. I'm impressed.
I needed a 4-inch hole for a vent. This made it easy. The pilot bit is strong. It didn't chip the wood. Very happy.
It's a good hole saw, but remember it needs an arbor. I didn't realize that. Once I got the arbor, it worked great. The cut is smooth.
Quick shipping and sharp.
I've used cheaper ones that dulled fast. This one seems to hold up. It cuts through plywood and MDF. The only downside is it's a bit expensive.
I've done six holes so far and it still cuts great. The size is accurate. I don't see any wear. Highly recommend.
Made my install easy.
I used it to run electrical wire. The hole is clean. The arbor fits my drill. It's a quality tool.
