Klein Tools 31872 – Frequently Asked Questions
1) What hole sizes come in the Klein Tools 31872 carbide hole cutter kit?
The Klein 31872 kit holds three cutters, 7/8 inch, 1-1/8 inch, and 1-3/8 inch, plus a spare pilot bit and a molded plastic case. Those three diameters line up with the knockout sizes electricians cut for 1/2, 3/4, and 1 inch conduit fittings in sheet metal enclosures.
2) How thick a piece of steel can these Klein carbide hole cutters go through?
Up to 3/16 inch material thickness in stainless steel, mild steel, iron, copper, or brass. Past that you are out of the cutter's range, and an integrated flange on each cutter physically stops you from drilling deeper than the sheet, so don't plan on using them on plate or solid stock.
3) Will a carbide hole cutter work in stainless steel where a bi-metal hole saw burns up?
That is the reason to reach for the 31872. The cutters are carbide and are rated for stainless steel along with mild steel, iron, copper, and brass up to 3/16 inch. For wood, plastic, or drywall, a standard bi-metal or hole saw set is the better tool; this one is built for metal.
4) Does the Klein 31872 kit include a pilot bit, or do I buy one separately?
A pilot bit is included, and so is a spare. It is a split point design, which keeps the bit from walking when you start a hole on a curved or slick metal surface. The spare matters because the pilot is the part that usually breaks first on a cutter kit.
5) What is the Klein part number I should order for the 4-piece carbide hole cutter kit?
Klein Tools model 31872 is the 4-piece carbide hole cutter kit with the carrying case. One part number covers the whole kit, so there is no size or finish choice to specify on the order.
6) Can I use this kit for punching holes in HVAC duct and electrical enclosures on site?
Yes, that is the working range. Sheet metal duct, panel and junction box bodies, and light gauge pipe all fall inside the 3/16 inch capacity, and the flange keeps the cutter from diving once it breaks through. For thicker structural steel or for clean large-diameter conduit openings in heavy enclosures, a knockout punch set is the right tool instead.
7) How big is the case on the Klein carbide hole cutter kit and how much does it weigh in the truck?
The kit measures 8 inches by 5.8 inches by 2.4 inches and weighs 1.45 pounds, so it drops into a tool bag pocket or a van drawer without taking a shelf. The case is rust-proof molded plastic, which is the point if it rides in a service vehicle year round.
