Order LookupHigh-Speed Steel Straight-Flute Hand Taps
Available43 products
High-speed steel taps provide good wear resistance in general purpose tapping applications in a range of materials. Also called hand taps, high-speed steel straight-flute taps are turned with a tap wrench to create or repair internal threads in blind holes and through holes. As the taps are rotated into a hole to create threads, the chips move into the flutes but are not evacuated.

Bright Finish Oversized High-Speed Steel Straight-Flute Taps
The bright finish on these taps provides a smooth, polished surface. Oversized taps have a slightly larger pitch diameter than standard taps. They are used to make threads in a hole before a coating or treatment is applied to the hole. Once the coating or treatment is applied, the threads will be reduced to the standard pitch diameter.

TiCN-Coated Oversized High-Speed Steel Straight-Flute Taps
The TiCN coating on these taps protects them from wear and is harder and more wear-resistant than a TiN coating. Oversized taps have a slightly larger pitch diameter than standard taps. They are used to make threads in a hole before a coating or treatment is applied to the hole. Once the coating or treatment is applied, the threads will be reduced to the standard pitch diameter.

Black-Oxide Oversized High-Speed Steel Straight Flute 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. Oversized taps have a slightly larger pitch diameter than standard taps. They are used to make threads in a hole before a coating or treatment is applied to the hole. Once the coating or treatment is applied, the threads will be reduced to the standard pitch diameter.
