Jobber Length Cobalt Drill Bits
Jobber Length Cobalt Drill Bits
These Jobber Length Drill Bits are designed for multi-purpose drilling in hard or abrasive materials including high-strength alloy steels, titanium, manganese steel, and inconel.
Aircraft Extension Cobalt Drill Bits
Aircraft Extension Cobalt Drill Bits
Aircraft Extension drill bits are similar in length to extra length bits, emphasizing reach over cutting depth, and have a shorter flute length (about the same as a jobber drill). This makes the bit much stronger and less susceptible to bending and breaking.
