For thin gauge material and sheet metal

These drill bits have short flutes as well as a short overall length for maximum rigidity when drilling in sheet metal. They are made with a cobalt blend for a longer life.

Features:

Made with premium grade cobalt HSS to drill harder materials

Cobalt drills can drill approximately 30% faster than HSS drills

Self centering 135° split-point for reduced thrust requirements and minimized walking

Special bronze SST surface treatment for extreme lubricity and life

Shorter length adds rigidity to the drill bit to reduce breakage

Round shank

Applications:

Drilling into sheet metal

Drilling of round surfaces

Drilling with stationary machines

Tech Tips:

Speed, feed, and lube are all critical to cutting tool performance

Proposition 65:

Cobalt metal powder
