Drill Bit Specification
This Drill America cobalt stub drill bit measures 31/32in and meets Aerospace Standard 907. The 135 degree split point is self-centering and reduces thrust during operation. Short rugged construction performs well across iron and steel families. It suits portable or machine drilling where spindle clearance is limited.
Target User Profile
Automotive and construction professionals who need a heavy duty screw machine drill for tight setups will find this bit suitable. Buyers who want more storage or require a different point angle for non-ferrous materials should look at something else. The 118 degree standard point applies only to sizes smaller than 1/16in or larger than 1/2in.
Setup Checklist
Verify that your drill chuck accepts a 31/32in shank before ordering. Confirm the workpiece material falls within the iron and steel families for best results. Ensure the drilling environment accommodates the short stub length and limited spindle clearance. Check local regulations regarding California Proposition 65 chemical warnings.
