Klein Tools 31852 – Frequently Asked Questions
1) What materials and thickness can the Klein 31852 carbide hole cutter go through?
It is made for sheet metal: stainless steel, mild steel, iron, copper and brass up to 3/16 inch thick. The carbide cutting edge is what lets it take stainless. It is not a wood or masonry bit.
2) Will the Klein 31852 hole cutter fit my drill chuck?
It has a 3/8 inch shank, so it seats in any 3/8 inch or 1/2 inch keyed or keyless chuck. A standard corded or cordless drill handles it.
3) What keeps the cutter from punching through into the wires or equipment behind the panel?
An integrated flange stops the cutter from travelling past the sheet metal once the hole is through, so you are not plunging into whatever sits behind the enclosure wall. The split point pilot bit also keeps the cutter from walking when you start the hole.
4) Can I replace the pilot bit on the Klein 31852 if it breaks or dulls?
Yes. The pilot bit is a serviceable part, and the correct replacement is Klein Tools 31874. Keeping a spare on the truck means a broken pilot does not retire the whole cutter.
5) Is the Klein 31852 the right tool for electrical enclosures and panel boxes, or should I use a knockout punch?
The 31852 is a drill-driven carbide cutter for sheet metal up to 3/16 inch, which covers most panel, enclosure and junction box walls, and it works where you only have access from one side. A hydraulic or ratcheting knockout punch needs a pre-drilled pilot hole and access to both faces, but it leaves a cleaner edge in heavier gauge. For quick 1/2 inch conduit entries in the field, the hole cutter is the faster route.
6) What part number do I order for the Klein 7/8-inch carbide hole cutter?
Order Klein Tools 31852. That is the 7/8 inch carbide hole cutter, sold as a single tool with its pilot bit; the pilot alone is 31874 if you need spares.
7) How heavy is the Klein 31852 hole cutter for pouch or kit carry?
It weighs 0.3 lbs and measures 4.8 by 3.188 by 3.188 inches, so it rides in a tool pouch or a small bit case without adding noticeable weight to the belt.
