12″ Aircraft Extension Drills – Champion & Drill America Extended Reach Drills
The 12″ Aircraft Extension Drills collection brings together extended-reach drill bits from Champion and Drill America, engineered for deep hole drilling and hard-to-access applications where standard bit lengths fall short. These drills provide a 12-inch overall length to reach through stacked materials, aircraft assemblies, ductwork, structural frames and other confined spaces, giving professionals the extended access they need without resorting to multiple tool changes.
Champion’s 12″ aircraft extension drills are crafted from high-speed steel with a 135° self-centering split point, which reduces walking and improves accuracy on flat, curved or angled surfaces. Champion’s black oxide corrosion-resistant finish and spring-tempered shank further enhance durability and reliability for everyday use on job sites and in fabrication shops.
Drill America also offers 12″ extra-length extension drills in high-speed steel and premium cobalt designs from their A-C EXT category, providing enhanced heat resistance and longevity for tougher materials and more demanding drilling conditions. These bits deliver dependable performance for steel, aluminum, stainless and general machinable materials where extended reach is required.
