The bright finish on these taps provides a smooth, polished surface.

The TiN coating on these taps protects them from wear and allows them to be used at higher speeds than taps with a bright finish. Non-coolant-through taps do not have coolant holes, so a separate hose is required to bring coolant to the cutting area if it is needed.

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.

The TiCN coating on these taps protects them from wear and is harder and more wear-resistant than a TiN coating. Non-coolant-through taps do not have coolant holes, so a separate hose is required to bring coolant to the cutting area if it is needed.

The left-hand taps in these sets are used to create internal threads in holes in applications where left-hand fasteners will be installed in the holes.

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.

The TiN coating on these taps protects them from wear and allows them to be used at higher speeds than taps with a bright finish. Coolant-through taps have holes that allow coolant to flow to their tip to reduce heat and friction during threading tasks.

Once the coating or treatment is applied, the threads will be reduced to the standard pitch diameter.

The TiAlN coating on these taps withstands high temperatures and protects the taps from wear. It allows the taps to be used at faster speeds than taps with a bright finish, and it resists cracks and oxidation better than TiN or TiCN coatings.

The TiCN coating on these taps protects them from wear and is harder and more wear-resistant than a TiN coating. Coolant-through taps have holes that allow coolant to flow to their tip to reduce heat and friction during threading tasks.
