Aircraft Extension Drills – Champion & Drill America Extended Reach Drilling Series

The Aircraft Extension Drills collection brings together extended-reach drill bits from Champion and Drill America, engineered for drilling holes in hard-to-reach places where standard bit length isn’t enough. These drills are ideal for aircraft assembly, sheet metal work, structural frame drilling, maintenance tasks and fabrication where long reach and precision are required. Champion’s 6" and 12" aircraft extension drills and Drill America’s HSS and cobalt extension drills deliver reliable performance in aluminum, mild steel and structural alloys.

Aircraft extension drills feature a 135° split point for fast penetration and reduced walking, even on curved or angled surfaces. The extended shank length gives technicians the ability to drill deep into assemblies, through stacked material or into confined spaces without changing tooling or setups. Whether you need general-purpose extension drills from Champion or the cobalt upgrades from Drill America, this collection covers every extended-reach drilling need.
