11/32in Cobalt Extension Drill Bit

The Drill America cobalt aircraft extension bit measures 11/32in with a 6in overall length. Its split-point tip reduces walking on hard metals. Cobalt steel construction resists heat during extended drilling sessions. Suitable for maintenance tasks requiring extra reach in confined spaces.

Check chuck capacity before ordering

Verify that your drill chuck accepts a 11/32in shank diameter. Confirm the 6in overall length clears the workpiece and any surrounding obstructions. Ensure the 3-7/16in flute length matches the required hole depth. This bit is not for buyers who need a shorter bit for tight clearance or a different shank size for smaller chucks.
