CRUSHER M 8 DIN-371C (6GX) HSSE-PM TiN Machine Tap

In a busy CNC machining cell, a technician loads the CRUSHER M 8 tap into the spindle to thread through holes in a batch of 316 stainless steel flanges. The spiral point geometry pushes chips forward, preventing clogging and allowing uninterrupted production. With its powder metallurgy HSSE-PM substrate and TiN coating, this tap delivers consistent thread quality and long tool life even in demanding alloy steels.

Key specifications

• Thread standard: Metric Coarse, M8 × 1.25 mm
• Tap standard: DIN 371C, tolerance class 6GX
• Material: HSSE-PM (high-speed steel with cobalt, powder metallurgy)
• Coating: TiN (titanium nitride)
• Lead-in form: C (2–3 threads), spiral point flute
• Total length: 90 mm, thread length: 18 mm
• Shank diameter: 8 mm, square drive: 6.2 mm
• Cutting direction: right-hand

Why choose it

The CRUSHER series is engineered for high-performance through-hole tapping. The powder metallurgy HSSE-PM base offers superior toughness and wear resistance compared to conventional HSS, while the TiN coating reduces friction and prevents built-up edge. The 6GX tolerance class ensures a slightly larger pitch diameter, ideal for threads that will receive coatings or require a looser fit. The spiral point design efficiently evacuates chips forward, making it suitable for high-speed operations in steels, stainless steels, and cast iron.

Ideal use cases

• Through-hole tapping in alloyed and unalloyed steels
• Stainless steel components requiring reliable thread quality
• Cast iron parts in automotive and general engineering
• CNC machining centers and high-volume production lines

Good to know

This tap is designed for machine tapping with a recommended cutting speed appropriate for the workpiece material. Always use proper coolant or cutting fluid to maximize tool life. The DIN 371C standard ensures compatibility with standard tap collets and holders. For blind holes, consider a spiral flute tap instead.
