Lenox 30960MVB412 VARI-BIT Step Drill Bit, 4mm - 12mm

Save time because you don't need to change drills for different-sized round holes in thin materials. Each drill acts as a pilot for the next size. The enhanced 2-flute design removes chips rapidly and cuts fast, clean, round, accurate, and burr-free holes. High-speed steel with steam oxide coating will cut through materials faster than standard bits, including stainless Steel up to 1/8-inch thick. The non-skid, self-starting tips penetrate faster and prevent "walking" across flat or curved work surfaces. LENOX Tools VARI-BIT Step Drill Bit, 4mm - 12mm (30960MVB412).
