Drill America 17/32in Reduced Shank Cobalt Silver & Deming Bit

17/32in Reduced Shank Cobalt Drill Bit

This 17/32 inch cobalt steel drill bit features a reduced shank design that fits standard 1/2 inch chucks. The bronze oxide surface treatment on the flutes helps reduce friction and heat buildup during drilling operations. It is suited for general-purpose metalworking tasks where a durable, high-speed steel alternative is required.

Sustained Load Performance

Cobalt steel construction maintains hardness at elevated temperatures better than standard high-speed steel, allowing the bit to resist softening during prolonged cutting. The reduced shank design transmits torque effectively without requiring a larger chuck capacity. Users should apply steady feed pressure and appropriate cutting fluid to maximise tool life when drilling tough alloys or deep holes.
