Extension Taps
Available117 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.
Tap Finish
Bright Finish High-Speed Steel Spiral-Point 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-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.

Black-Oxide Finish High-Speed Steel Spiral-Point 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-speed steel taps provide good wear resistance in general purpose tapping applications in a range of materials. 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.

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.

Bright Finish High-Speed Steel Extension Taps for Pipe
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. Pipe taps come in thread standards and sizes that are used on parts in pipe systems. They create or repair internal threads in pipe and fittings so they can form a pressure-tight seal with parts that have matching external threads.

Bright Finish Carbide Straight-Flute Extension Taps
The bright finish on these taps provides a smooth, polished surface. Carbide taps are harder than high-speed steel and high-performance taps. They resist high temperatures and are suitable for high-speed tapping. Carbide taps are more brittle than high-speed steel and high-performance taps and require a rigid setup. 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.

Bright Finish Carbide Thread-Forming Extension Taps
The bright finish on these taps provides a smooth, polished surface. Carbide taps are harder than high-speed steel and high-performance taps. They resist high temperatures and are suitable for high-speed tapping. Carbide taps are more brittle than high-speed steel and high-performance taps and require a rigid setup. 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.
