Champion CS12X 12" HSS Aircraft Extension Drill Bits

Champion CS12X aircraft extension drill bits are 12" long high speed steel drill bits designed for long-reach drilling applications where extra length is needed. These extension drill bits are commonly used for aircraft assembly work, aluminum drilling, low-to-medium steel alloy drilling, maintenance, fabrication, and hard-to-reach hole locations.

Long Drill Bits for Aluminum & Low-to-Medium Steel Alloys

The CS12X series is ideal for drilling aluminum and low-to-medium steel alloys. The 12" overall length helps reach areas where standard jobber drill bits are too short, while the flute length remains the same as a standard jobber drill for controlled chip evacuation.

135° Split Point Extension Drill Bits

These Champion aircraft drill bits feature a 135° self-centering split point to help reduce walking on the workpiece. This makes them useful for more accurate starts when drilling metal, aluminum, and alloy materials in long-reach applications.

Black Oxide Treated High Speed Steel for Longer Tool Life

Champion CS12X drill bits are made from black oxide treated high speed steel to help improve heat resistance and tool life. The spring tempered shanks are designed to help prevent permanent bending when drilling holes that are not in direct alignment, because apparently even holes enjoy being inconvenient.
