Aircraft Extension HSS Drill Bits
Aircraft Extension HSS 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.
Mechanics Length HSS Drill Bits
Mechanics Length HSS Drill Bits
These Mechanics Length Drill Bits have a shorter overall length, in-between a jobber and screw machine drill, which allows access to those jobs in tight spaces. The shorter length results in a sturdier, more rigid drill that is less prone to breakage.
