Milwaukee One-Piece Carbide Hole Cutter, 3"

Milwaukee One-Piece Carbide Hole Cutter, 3"

The Milwaukee 49-57-8643 One-Piece Carbide Hole Cutter (3") is a durable, metal-cutting hole cutter built for smooth, long-lasting performance in hard metals, featuring carbide teeth that deliver up to 10X life vs. standard hole saws. Its stop shoulder helps prevent over-drilling by limiting cuts to 3/16" depth, while the spring-loaded pilot bit supports fast drilling and clean plug ejection. Designed for drill/drivers, it uses a 3-flat Secure Grip shank for strong bit retention and added control.
