Klein Tools 31872 4-Piece Carbide Hole Cutter Hole Cutter Kit

This 4-piece Carbide-Tipped Hole Cutter kit is designed for heavy duty use and is made from durable materials for long-lasting performance.

The set includes 7/8-Inch, 1-1/8-Inch, and 1-3/8-Inch cutters, as well as an extra pilot bit. Its integrated flange prevents drilling beyond the sheet metal, and the split point pilot drill bit prevents bit walking. The kit comes in a rust-proof, molded plastic carrying case and is suitable for conduit and pipe sizes between 1/2-Inch (1.3 cm) and 1-Inch (2.5 cm).
