Thread DIN 371-C M4x0.5 -6H R40 H1 HSSE INOX ISO2 FANAR.

. INOX. A group of taps with geometries and microgeometries designed for machining stainless and acid-resistant steels.The material of the tool is HSSE high-speed steel with 5% cobalt content, guaranteeing high blade stability and the possibility of efficient machining. . C-R40-HL DIN-371. For stainless and acid-resistant steels. Protection. . Tools are protected from wear by a multi-layer HL coating. The main elements are the TiAlN base, which is an ideal temperature barrier, and the top layer of tungsten carbide in a carbon matrix (WC/C) reduces build-up, great for machining ductile materials.
