Cobalt Stub Drill Bit
This Drill America cobalt heavy duty stub drill bit measures 43/64in and is built to Aerospace Standard 907 for industrial drilling tasks. It suits mechanics and fabricators who need a short, rigid cutter for portable or machine work in iron and steel families.
135 Degree Split Point
The 135 degree split point is self-centering and reduces thrust during drilling, which helps accuracy on hard materials. Sizes above 1/2in normally use a 118 degree standard point, so this bit retains the sharper geometry for better performance in tough alloys.
For Limited Clearance Setups
Buyers who need a compact drill for screw machine setups with restricted spindle clearance will find the short length practical. Workers who require longer flutes for deep holes or bits for non-ferrous materials should look at something else.

Questions about this item
How does the 135 degree split point change drilling performance?
The 135 degree split point is self-centering and reduces the thrust needed to start the hole, improving accuracy on portable or machine drilling.
What does the Aerospace Standard 907 designation indicate about this bit?
Aerospace Standard 907 means the cobalt screw machine drill is manufactured to a recognised aerospace specification for quality and dimensional consistency.
Will the 43/64in stub length fit in a standard drill chuck?
The short, rugged stub construction is designed for limited spindle clearance, so it fits standard chucks where longer bits would not.
