The DEWALT DWA1860 3-3/4-inch hole saw is built for plumbers, electricians, and remodelers cutting holes in wood, drywall, and light metal. Its bi-metal construction combines high-speed steel teeth with a tough steel backer for durability, while the double-tooth design adds strength to each tooth. The deep cut style allows you to cut 2x material in a single pass, saving time on every job.
Improved plug ejection lets you remove the slug quickly after the cut. The thick, hardened backing plates prevent thread stripping from the arbor, even with repeated use. With the highest high-speed steel height in the industry, this hole saw keeps cutting longer before dulling.
Pair it with a 3/4-inch pilot bit and a DEWALT hole saw arbor (sold separately). For best results, run at moderate speed and let the saw do the work. This deep cut design is ideal for cutting through 2x4 and 2x6 framing, door lock blocks, and metal studs in one pass.

Match the pilot bit diameter to the hole saw size: a 3/4-inch pilot bit is ideal for a 3-3/4-inch saw because it centers the cut without forcing the saw. An arbor with a quick-change hex shank can speed up changes between sizes.
Start at low RPM until the pilot bit centers, then increase speed. Don’t force the saw; let the teeth cut at their own rate. Back out slightly if you see burning, and vacuum chips from the teeth before ejecting the plug. This keeps the saw cutting cool and extends its life.
Use a DEWALT hole saw arbor with a 3/4-inch pilot bit. The saw has a standard thread pattern that fits DEWALT and most compatible arbors.
Yes, it can cut light metal such as electrical boxes and metal studs when used at the right speed and with cutting fluid if needed.
The deep cut style lets you saw 2x lumber (about 1.5 inches) in one pass, without stopping to remove a plug.
No, the pilot bit and arbor are sold separately.
I used this to cut through a 2x6 with no pilot hole issues. It cut deep and clean. The plug came out easily.
