Specification

Application

For producing metric threads on CNC machines or conventional machines in blind holes in the steel, (stainless steel), non-ferrous metals and (cast iron) material groups up to a strength of 1000 N/mm².

Execution

Structural dimensions according to: DIN 371 = reinforced shank (up to M10), DIN 376 = protruding shank (from M12)

Advantage

Long service life and good process reliability due to innovative cutting geometry and universal use for maximum application versatility
Optimised geometry for lathes as a fixed tool
