Extension Taps
Available7 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.

TiCN-Coated High-Performance Spiral-Point Extension Taps
The TiCN coating on these taps protects them from wear and is harder and more wear-resistant than a TiN coating. High-performance taps are harder and more wear-resistant than high-speed steel taps. They provide good precision and accuracy in threading tasks. Spiral-point taps have straight flutes with a spiral point that pushes chips in front of the tap as it moves into a hole and out the other side, eventually forcing the chips out of the hole. They are used for threading through holes.

TiCN-Coated High-Performance Spiral-Flute Extension Taps
The TiCN coating on these taps protects them from wear and is harder and more wear-resistant than a TiN coating. High-performance taps are harder and more wear-resistant than high-speed steel taps. They provide good precision and accuracy in threading tasks. 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.

Black-Oxide Finish High-Performance Spiral-Flute Extension Taps
The black-oxide finish on these taps retains lubricants to improve the taps' wear resistance and chip flow. Black-oxide taps should only be used on ferrous metals. High-performance taps are harder and more wear-resistant than high-speed steel taps. They provide good precision and accuracy in threading tasks. 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.
