Klein Tools 31856 – Frequently Asked Questions
1) What conduit size does the Klein Tools 31856 hole cutter make a knockout for?
The 31856 cuts a 1-1/8 inch hole, which is the clearance size for 3/4 inch conduit and pipe. If you need a different trade size, you need a different diameter cutter: this one is a single fixed 1-1/8 inch diameter.
2) What materials and thickness can this carbide hole cutter handle?
The 31856 cuts stainless steel, mild steel, iron, copper and brass sheet up to 3/16 inch thick. That covers enclosure walls, panel boxes, strut, and sheet metal duct. It is a sheet metal cutter, not a bit for solid stock or masonry.
3) Does the Klein 31856 come with a pilot bit, and what do I order when it breaks?
It uses a split point pilot drill bit, which keeps the cutter from walking when you start a hole on a curved or slick panel. The replacement pilot bit is Klein 31874, so keep one in the van if you cut holes regularly.
4) How do I keep from punching through wiring behind the panel when drilling an enclosure?
An integrated flange on the 31856 stops the cutter from travelling past the sheet metal, so once the hole breaks through, the body bottoms out instead of plunging. That matters when you are drilling a live-ish panel wall with conductors or equipment just behind it. Eye protection for you and anyone nearby is still required.
5) Is a carbide hole cutter better than a bi-metal hole saw for drilling steel enclosures?
For sheet metal up to 3/16 inch, the carbide tooth design on the 31856 cuts faster and lasts longer than a bi-metal saw, and it handles stainless, which chews up bi-metal teeth quickly. A bi-metal hole saw is still the right call for wood, plastic, and thicker stock the 3/16 inch limit rules out.
