DeWalt HSS-Co Metal Drill Bit Set 13 pcs

Alloy steel with 5% cobalt
4 times longer life compared to standard HSS-R metal drill bits
Optimized pilot point on our 3.2mm to 8mm drill bits for faster starts, reduced bit wandering for better cutting. 

DeWalt’s new multi-step shank on sizes 8.5mm and larger for no-slip, fast starts and accuracy
Suitable for portable or stationary drilling of high-alloy steels and metals with a tensile strength of up to 1100N/mm²
Non-rotating three-sided shank for optimal grip in the drill chuck
Increasing the central core thickness towards the chuck improves resistance to breakage, especially when used freehand.
Ideal for harder metals such as bronze, cast iron, stainless steel and titanium
Made to penetrate hard metals including stainless steel, these high-performance bits are made from industrial cobalt for long life, with a pilot point and a 135-degree split point for fast, clean, and burr-free drilling. A thick core ensures extreme durability. A durable plastic case keeps the bits organized.
