Klein Tools 31873 – Frequently Asked Questions

1) What hole sizes come in the Klein Tools 31873 hole cutter kit?
The Klein 31873 kit covers six cutter sizes: 7/8, 1-1/8, 1-3/8, 1-3/4, 2 and 2-1/2 inch. That spans conduit and pipe knockouts from 1/2 inch up to 2 inch trade size. Two spare pilot bits round out the 8-piece count, so you are getting six cutters plus the extra bits rather than eight different diameters.
2) Will these carbide hole cutters go through a stainless steel enclosure?
Yes. The 31873 cutters are rated for stainless steel, mild steel, iron, copper and brass sheet up to 3/16 inch (0.5 cm) thick. Stainless panel boxes, pull boxes and troughs are within range. Anything thicker than 3/16 inch is outside what these are built to cut.
3) I need a 2-inch conduit knockout in a panel. Does this Klein kit cover that?
It does. The 2-1/2 inch cutter in the 31873 set is what produces a 2 inch trade size conduit hole, and the kit is specified for conduit and pipe from 1/2 inch through 2 inch. If you need larger than 2 inch trade size, this set stops there.
4) What keeps the cutter from punching through and hitting wiring behind the sheet metal?
Each cutter in the 31873 set has an integrated flange that stops the tool from drilling past the sheet metal. That matters when you are cutting into an occupied enclosure or a box with conductors behind the wall you are cutting. The split point pilot drill bit also keeps the cutter from walking as you start the hole.
5) Hole cutters or a step bit for electrical panel work?
A step bit is fine for thin sheet and smaller holes, but it tops out well below conduit sizes and tends to leave a tapered edge. The Klein 31873 carbide cutters are the tool when you need a clean, full-diameter hole from 7/8 up to 2-1/2 inch in steel, stainless, iron, copper or brass up to 3/16 inch thick. For a one-off hole in a thin device box, a step bit is simpler; for repeat conduit knockouts across a job, the cutter set is what holds up.
6) Does the Klein 31873 hole cutter kit come with a case, and how big is it to haul around?
All eight pieces ship in a rust-proof molded plastic carrying case. The kit measures 12.1 by 9.7 by 3.5 inches and weighs 4.3 lbs, so it drops into a tool bag or van bin without a dedicated shelf.
7) Do I need to order spare pilot bits with the Klein 31873 kit?
Not right away. Two extra pilot bits are packed in the 31873 kit, which is the part that normally wears or snaps first. Order the exact replacement pilot bit for the Klein cutter you are running when those are used up.
