The OSG Threading Tap Metric A-OIL-Spiral Point is a right‑hand tapping tool designed specifically for through‑hole threading. Built with a powder‑metal substrate and TiCN coating, it delivers durable, precise M22 x 2.5 threads in DIN376 through‑holes for reliable, repeatable performance.

• Threading geometry: A‑OIL‑Spiral Point design to push chips ahead and improve evacuation
• Material: Powder‑metal substrate for enhanced wear resistance and longevity
• Coating: TiCN coating to reduce friction and improve heat resistance
• Handedness: Right‑hand internal tapping for standard thread creation
• Through‑hole compatibility: DIN376‑compliant holes for accurate alignment and clean threads
• Size: M22 x 2.5 metric thread
• Application: Optimized for high‑speed threading across a variety of materials

The combination of a tough powder‑metal substrate and a low‑friction TiCN coating helps extend tool life even in demanding tapping tasks. The spiral point actively evacuates chips, reducing the chance of clogging and ensuring smoother starts and consistent thread quality in through‑hole work. Ideal for production runs or on‑demand repairs that require reliable, precise M22 x 2.5 threads in DIN376 holes.
