Ranging from 1/16 to 1/2" (1.6 to 12.7 mm) in 1/32" (0.8 mm) increments, this 15-pack cobalt drill bit set is designed for drilling high-tensile materials such as stainless steel, titanium, and Inconel. The 135° split point tips facilitate fast penetration and accurate drilling, while the cobalt construction maintains high red hardness at speeds up to 30% greater than conventional M2 high-speed steel. For organized transport and access, the bits are housed in a round Bit Cooler index.
