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.
