A 4-piece carbide-tipped hole cutter set for drilling clean holes in tougher sheet materials than a standard bi-metal saw handles well, packed in a rust-proof molded plastic carrying case.
- Cuts: stainless steel, mild steel, iron, copper, and brass sheet up to 3/16 inch (0.5 cm) thick
- Set contains: 7/8-inch, 1-1/8-inch, and 1-3/8-inch cutters plus an extra pilot bit
- Pilot bit: split point design prevents bit walking
- Conduit and pipe sizes covered: 1/2 inch (1.3 cm) to 1 inch (2.5 cm)
- Integrated flange stops drilling beyond the sheet metal
Best for: electricians cutting conduit knockouts in stainless steel, mild steel, or other tougher sheet materials where a standard hole saw wears out fast.
