TOP line. In HSS-E steel, particularly treated for superior performance and long life. Ground and polished after hardening. Cutting geometry optimized for maximum chip evacuation.
Reinforced shank (from 12mm, reduced shank), correct chamfer for through holes.
Thread: Metric - Coarse Pitch M - DIN 13 (DIN 371/376). Tolerance ISO2/6H. Right-hand use. TiAlN coated. For all types of steels, also for hardened non-alloy steel, stainless steel, nitrided steel, non-oxidizable and antacid steel up to 1200 N / mm2, aluminum, its alloys and long-chipping metals.
When the stocks will be run out, the taps will be provided with AlTiZrN coating in golden color instead of TiAlN coating.
