Features

Extended reach: 6-inch extension enables drilling in recessed or hard-to-access holes without repositioning the workpiece.

Heat and wear resistance: Cobalt alloy improves hardness and heat tolerance during drilling of hard metals, reducing premature dulling.

Size precision: No. 19 diameter supports consistent hole sizing in metal components.

Rigid extension design: Maintains alignment and reduces flex when drilling through dense materials.

Aerospace-oriented utility: Suited for demanding maintenance tasks where long-reach drilling is required.
