6″ Aircraft Extension Drills – Champion & Drill America Deep Reach Drill Bits

The 6″ Aircraft Extension Drills collection features extended-reach drill bits from both Champion and Drill America designed specifically for hard-to-reach drilling tasks. These aircraft extension drills provide additional reach with a 6-inch overall length, allowing professionals to access deep holes and confined spaces in assemblies, frames, ductwork and aircraft structure where standard bits can’t reach. 

Champion’s 6″ aircraft extension drills such as the CS6X and 7006 models are constructed from high-speed steel with a 135° self-centering split point to prevent walking on flat or curved surfaces, black oxide treatment for corrosion resistance, and spring-tempered shanks to resist permanent bending under misalignment. 

Drill America’s 6″ aircraft extension bits are available in both high-speed steel and premium cobalt variants, delivering longer tool life in tougher materials and high-tensile applications. These bits are ideal for drilling in aluminum, mild steels and general machinable materials when extra reach is required.
