Description

Specs

  • Diameter: 5/16 in
  • Overall length: 6 in
  • Material: Cobalt alloy
  • Quantity: 1 PC
  • Type: Cobalt Aircraft Extension Drill Bit
  • Extension length: 6 in

Features

  • Wear and heat resistance: Cobalt alloy construction increases wear resistance and heat tolerance, extending bit life in hard metals encountered in aerospace fabrication.
  • Extended reach: 6-inch extension design allows access to tight or recessed locations common in aircraft maintenance, interiors, and wing/fuselage assemblies.
  • Rigid, low chatter: Single-piece construction enhances rigidity and reduces chatter under load for more stable drilling.
  • Accurate start and cut: Optimized cutting geometry supports consistent cutting action and reduces wandering when starting holes in metal, improving first-pass accuracy.
  • Use cases: Ideal for extended-reach holes in hard alloys, stainless steel fasteners, and aluminum components with hidden access such as engine nacelles, interior brackets, and fittings.
