27/32in Cobalt Stub Drill Bit
This cobalt stub drill bit meets Aerospace Standard 907 for demanding metalworking tasks. The 135 degree split point is self-centering and reduces thrust during drilling. It suits portable or machine drilling in iron and steel families. Automotive and construction professionals often choose it where spindle clearance is limited.
Installation ease and common issues
The short, rugged construction fits tight setups such as screw machine configurations. No special tooling is required beyond a standard chuck that accepts the shank. The split point helps prevent walking on hard surfaces. Users must observe California Proposition 65 warnings for cobalt content.
Capacity and headroom
Designed for a broad range of ferrous materials in maintenance and production environments. The stub length provides rigidity but limits reach compared with jobber-length bits. Sizes larger than 1/2in switch to a 118 degree standard point per the specification. It is not intended for non-ferrous or composite materials.

Questions about this item
How do I confirm the 135° split point is self-centering after setup?
The 135 degree split point is self-centering and reduces thrust, so the bit should start on centre without walking when you begin drilling.
What comes in the box and what must I buy separately?
The box contains the single 27/32in cobalt stub drill bit; no additional accessories or holders are included.
Which version should I choose — the 135° split point or the 118° standard point?
Sizes smaller than 1/16in and larger than 1/2in use the 118 degree standard point; this 27/32in bit is supplied with the 135 degree split point.
