ROK 21pc Cobalt Drill Bit Set

This 21-piece M35 HSSE Drill Bit Set is ideal for tough application drilling into steel, stainless steel, cast iron, and hardened metals. The highly heat-resistant cobalt high-speed steel delivers a durable construction to power through hard metals without wear longer. A 135° split point design provides a quicker drilling penetration and a precision-start for clean and accurate holes without walking, while a 3-flat shank minimizes spinning in the chuck for a secure bit hold.
