Features
[1 PC] 11/64″ x 6″ Cobalt Aircraft Extension Drill Bit combines cobalt alloy hardness with high-speed steel formulation for improved wear resistance and heat tolerance when drilling hard metals.
Extended reach enables access to deep or recessed holes in aircraft panels and similar applications where standard bits cannot reach.
Maintains cutting geometry under demanding drilling tasks, reducing wandering during deep-hole work and improving hole circularity.
Suitable for metal, alloy, and composite drilling scenarios where extended reach provides practical value.
