The OSG Threading Tap, Metric A‑Spiral Flute, is engineered for precise blind-hole tapping in metric sizes. With a +0.1 oversize tolerance and TiCN coating, it delivers reliable threads in demanding production environments while maintaining consistent fit for standard fasteners.

• Size & Standard: M8 x 1.25 thread for metric blind-hole applications, DIN371 compliant
• Flute Design: A‑spiral flute optimizes chip evacuation in blind holes to reduce breakage risk
• Material: Powder metal body delivers high strength and wear resistance under demanding machining
• Coating: TiCN coating increases surface hardness and lowers friction for longer tool life
• Hand: Right-hand threading for common automotive and industrial applications
• Oversize Tolerance: +0.1 tolerance provides consistent tapping performance with dependable thread formation
• Application Focus: Designed specifically for metric blind-hole tapping where depth and precision matter

The combination of a powder metal body and TiCN coating means you can run longer between sharpenings, even in tough materials, while the spiral flute helps chips escape efficiently in deep blind holes. The +0.1 oversize makes assembly easier in scenarios where a slightly looser fit is preferred without sacrificing overall thread integrity. This tap is built for reliability in high-speed production and for shops that demand repeatable, high-quality threading results in metric blind-hole work.
