The properties of stainless and acid-proof steels, classified as ISO M materials, are such that specialist tools are required to machine them.
Tapping these materials using standard tools can often lead to tool breakage, because of their high level of toughness and tendency to fuse. The new high-end TC142 blind hole taps from Walter are precisely designed for machining ISO M materials.
The TC142 comes in two variants: The WW60RB grade HSS-E-PM variant impresses with a long tool life and high cutting speeds thanks to its wear-resistant coating – ideal for operators machining in large quantities. The second variant in WY80FC with a vaporised surface guarantees a high level of process reliability thanks to its excellent chip control.
