Cobalt Heavy Duty Drill Bit 23/32in

The Drill America cobalt heavy duty split point stub drill bit measures 23/32in and conforms to Aerospace Standard 907. It is built for professionals in automotive and construction who need a short, rugged bit for portable or machine drilling in iron and steel families where spindle clearance is limited.

Sustained Drilling Performance

The 135 degree split point is self-centering and reduces thrust, allowing the bit to start accurately without wandering during extended use. Short, rugged construction maintains rigidity across a broad range of ferrous materials, preventing deflection that can worsen as holes deepen under continuous load.

Heat and Wear Characteristics

Cobalt alloy construction resists heat buildup better than standard high-speed steel, preserving cutting edges during repetitive drilling cycles. The 118 degree standard point on sizes larger than 1/2in provides durability for heavy feeds. California Proposition 65 warnings apply for cancer and reproductive harm.
