Milwaukee 49-22-4155 Master Plumbers Ice Hardened Hole Saw Kit,  18-Piece

From the Manufacturer

Milwaukee Electric Tool Corporation introduces Ice Hardened hole saws, a new generation of hole saws that offer up to 50% longer life than the competition and are ideal for metal and wood cutting in a wide variety of HVAC, electrical, plumbing and maintenance/repair applications.
