The OSG Metric Spiral Point Threading Tap in HSS‑E with steam oxide coating is built for through‑hole tapping where precision and durability matter. It’s designed for professional workflows that demand reliable thread quality and extended tool life.

• Size: M36 x 4 metric through‑hole threading tap
• Material: HSS‑E (high‑speed steel with cobalt) for enhanced hardness and heat resistance
• Coating: Steam oxide finish to reduce friction, improve wear resistance, and extend life
• Thread geometry: Spiral point design that promotes fast chip evacuation and clean thread formation
• Application: Optimized for through‑hole tapping, delivering consistent results in demanding operations
• Brand and build: OSG precision tooling trusted for quality and long‑lasting performance

This tapping solution helps you achieve accurate M36 x 4 threads in a single pass, reducing rework and improving production efficiency. The cobalt‑enhanced HSS‑E composition maintains cutting sharpness under higher temperatures, while the steam oxide coating minimizes wear and friction. The spiral point geometry actively pushes chips out of the hole, preventing clogging and maintaining steady cutting progress in through holes. Ideal for metalworking environments where dependable performance and precise threading matter, this tap supports consistent results and longer tool life across tough materials.
