Features

    Long-reach design enables access to deep or hard-to-reach holes common in aircraft maintenance and metal fabrication.

    Cobalt alloy provides enhanced heat resistance and wear life, preserving edge integrity when drilling tougher metals.

    Well-suited for repetitive drilling through hard alloys (e.g., stainless steel, titanium) where standard bits dull quickly.

    One-piece construction minimizes misalignment and delivers reliable performance in extended-reach applications.

    Best used for metalworking tasks involving deep bore holes in aluminum, stainless steel, and other hard alloys.
