Extension Taps
Available2 products
Extension taps have long shanks that allow them to tap deep holes and access holes that a standard tap could not reach. They create internal threads in holes, and their reduced-diameter shank clears the hole when tapping a hole at a depth that is greater than the taps' thread length.

Bright Finish High-Speed Steel Spiral-Flute Extension Taps
The bright finish on these taps provides a smooth, polished surface. High-speed steel taps provide good wear resistance in general purpose tapping applications in a range of materials. Spiral-flute taps pull chips out and away from the hole as the tap moves into the hole to create threads, which helps prevent chips from packing in the hole. They are used for threading blind holes.
