Klein Tools 31854 – Frequently Asked Questions
1) What materials will the Klein 31854 hole cutter go through?
The Klein Tools 31854 carbide hole cutter is made for sheet metal: stainless steel, mild steel, iron, copper and brass. It is rated for sheet up to 3/16 inch (5 mm) thick. It is not a wood or masonry bit, and anything thicker than 3/16 inch is outside what it is built to cut.
2) What size hole does the Klein 31854 cut?
It cuts a 1 inch hole. For electricians that is the common size for 3/4 inch trade conduit fittings in a panel or enclosure wall, so one pass gives you a clean, round knockout-style opening in the gauge of steel a load center or pull box is made from.
3) How do I keep from punching through into the wiring behind the sheet metal?
The 31854 has an integrated flange that stops the cutter from travelling past the sheet metal once the hole is through. That is the feature that makes it usable on a live enclosure or a box with conductors sitting close behind the wall you are cutting.
4) Will a carbide hole cutter wander when I start the cut on a panel?
No. The 31854 uses a split point pilot drill bit, which bites on contact instead of skating across the face of the panel. You still want the piece clamped or the enclosure braced, but you do not need to center punch it first the way you would with a plain twist bit.
5) Should I use a carbide hole cutter or a knockout punch set for 1 inch holes in an enclosure?
Different jobs. A knockout punch needs a pilot hole and access to both sides of the panel, and it is the cleaner choice when you have the enclosure open and empty. The 31854 carbide cutter works from one side with a drill only, which is why it wins on field retrofits and on boxes already full of conductors, where the flange keeps you from plunging through. For sheet heavier than 3/16 inch, go to a punch.
6) What is the Klein part number I should order for the 1 inch carbide hole cutter?
Order Klein Tools 31854. That single manufacturer part number covers the 1 inch size; the cutter and its pilot bit come as the one assembly, so there is no separate arbor or pilot to specify.
