CRUSHER M 8 DIN-371C (6HX) SR HSSE-PM WGN TiCN strojný závitník

Powder-metallurgy HSSE-PM with TiCN coating gives this M8 machine tap exceptional wear resistance and a long service life in high-volume through-hole threading. The spiral point geometry pushes chips forward, eliminating flute clogging and enabling faster, smoother tapping in steel, stainless steel, and cast iron.

Overview

The CRUSHER M 8 is a premium spiral point tap engineered for metric coarse threads in through holes. Manufactured to DIN 371 with a 6HX tolerance class, it delivers precise, consistent threads in demanding production environments. The C chamfer form (2–3 threads lead-in) reduces torque and improves thread quality, while the right-hand cutting direction suits standard machining centers and manual operations.

What stands out

• HSSE-PM powder metallurgy steel with cobalt for superior toughness and edge retention.
• TiCN (Titanium Carbonitride) coating reduces friction, prevents galling, and extends tool life up to 3× compared to uncoated taps.
• Spiral point (SR) flute design ejects chips forward, ideal for through holes and high-speed tapping.
• DIN 371 standard with reinforced shank and 6HX tolerance for reliable thread fit.
• Optimized for steels up to 1200 N/mm², stainless steels, and cast iron.
