Extension Taps
Available9 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 Thread-Forming 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. Thread-forming taps press against the sides of a hole to form threads as they are rotated into the hole. They don't produce chips, which eliminates the need to clear chips from the hole and prevents threads from being deformed during tapping.

TiCN-Coated High-Speed Steel Straight-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-speed steel taps provide good wear resistance in general purpose tapping applications in a range of materials. Straight-flute taps move chips into the taps' flutes but do not evacuate the chips as the taps are rotated into a hole to cut threads. They are used for threading through holes and blind holes.
