The DEWALT D180018IR deep cut hole saw is built for metalworkers, electricians, and serious DIYers who need clean holes in steel, stainless, and other tough materials. This 1-1/8-inch high-speed steel model features an optimized tooth design that increases drilling speed, plus a raised shoulder that helps prevent the drill from grabbing or breaking through when the cut is complete. The thin-wall construction improves chip removal and cutting efficiency, while the impact-rated backing plate is ready for impact driver use.
Unlike standard hole saws, the D180018IR is a deep-cut version with a longer cutting depth, so you can bore through nominal thickness materials without needing a separate extension. The high-speed steel teeth stay sharp through repeated use, and the spring-loaded plug ejection makes clearing the slug a one-second job. This saw is a smart choice for running conduit, pipe, cable, or installing hardware where speed and clean cuts matter.
Impact drivers deliver a lot of torque, and ordinary hole saws can twist or strip at the arbor. The D180018IR’s hardened backing plate and impact-rated design resist that stress, so you can use it with your impact driver or standard drill. It works with all standard hole saw arbors with a pilot bit, giving you flexibility on the job.
High-speed steel construction stays sharp for long runs in metal.
Deep-cut design reaches through thicker material without constant repositioning.
Impact-rated backing plate withstands impact drivers.
Raised shoulder helps prevent breakthrough when the hole completes.
Spring-loaded plug ejection makes plug removal quick.

A standard hole saw usually cuts about 1 inch deep. The DEWALT D180018IR deep-cut version goes deeper, so you can bore through thicker materials without stopping to clear chips or flip the work. That extra depth is a real advantage when you’re routing pipe or conduit through framed walls and subfloors.
Always use a pilot bit to keep the hole centered and let the saw do the cutting without forcing it. On metal, use a moderate speed and cutting fluid to keep teeth cool. When the plug ejects, clear it away quickly and inspect the hole for burrs.
Whether you’re an electrician pulling cable or a homeowner installing a deadbolt, the D180018IR gives you the speed, durability, and clean cuts you expect from a precision hole saw.
Yes, the D180018IR is impact rated and built to handle the torque of an impact driver, especially when used with a compatible arbor.
It fits standard hole saw arbors with a pilot bit, commonly 1/2-inch or 5/8-inch drive, depending on your drill or impact driver.
With a deep-cut design, it provides approximately 1-1/2 inches of cutting depth—enough for most conduit and piping applications.
Yes, it cuts wood and plastic, but it is optimized for fast metal drilling. For wood, you may want a standard wood-cutting hole saw depending on the size and finish required.
I used this to drill 1-1/8" holes in steel plate. It went through like butter. The deep cut design is nice because it captures more of the slug. It didn't overheat even with constant use. Great attachment.
Cuts steel, no problem.
I borrowed my husband's impact driver and this hole saw made a perfect hole in a stainless sink. Super fast. Great product.
It cuts well, but the pilot bit is a bit short. I had to use a guide on a thick piece of pipe. Once it bites, it cuts straight. The teeth are sharp and it doesn't grab. Overall, a decent tool.
It didn't last as long as I hoped. It got dull after a few uses on aluminum. Maybe I was pushing too hard.
I've used many hole saws in my plumbing career. This one is robustly built. It cut through cast iron with ease, which surprised me. The teeth are hardened and hold their edge. The size is perfect for running wires. It also fits on my impact driver with the hex shank. I've already recommended it to my colleagues.
Sharp, fast, worth buying.
It did the job on a metal door. The cut is smooth, but the teeth seem fragile if you hit a weld. Overall okay.
I'm an electrician and I need to drill through metal boxes all the time. This hole saw is my go-to. It creates clean, burr-free holes. The deep-cut design collects the slug. It's durable enough for daily use.
Cuts anything, highly recommend.
