6 Inch Aircraft Extension Drills are designed for drilling holes in aircraft assembly work where long reach is needed

Ideal for drilling aluminum and low to medium steel alloys

Drills will not walk on workpiece due to 135° self-centering split point

Flute length is the same as a standard jobber drill

Black Oxide Treated High Speed Steel enhances heat resistance and longer tool life

Spring tempered shanks prevent permanent bending when drilling holes not in direct alignment
