Two Blind Holes Tap Choices for Process Reliability

The high-end TC142 blind hole taps, used for machining stainless steels and ISO M materials, have a secondary application in ISO P materials, particularly in the softer steel which require more chip control. Tapping stainless using standard tools can often lead to tool breakage because of the material’s high level of toughness. The TC142 is designed to combat this failure mode.

Grade WW60RB grade provides for long tool life and high cutting speeds thanks to its wear-resistant coating, ideal for high-volume production. The second version is grade WY80FC, with a vaporized surface that guarantees a high level of process reliability thanks to its excellent chip control.
