OSG's Metric Spiral Flute Threading Tap, built from HSS-E and finished with a Steam Oxide coating, is designed for precise blind-hole threading in demanding metalworking environments. Suitable for professional shops and those who require reliable, long-lasting taps, this tool delivers consistent results at the M30 x 3.5 size.
- Material: HSS-E (high-speed steel with cobalt) for improved heat resistance and durability during tough threading tasks.
- Finish: Steam Oxide coating to enhance lubricity and help extend tool life under demanding cutting conditions.
- Flute Design: Spiral flute for efficient chip evacuation in blind-hole applications, helping maintain thread accuracy and reduce clogging.
- Size: Metric thread M30 x 3.5, suitable for large-diameter, medium-pitch threads.
- Application: Optimized for blind-hole threading where reliable depth control and clean starts are essential.
This tap is built to deliver consistent, high-quality threads while resisting wear and heat buildup. The combination of HSS-E material and the steam oxide finish supports longer tool life, reduced downtime, and steadier performance across critical machining tasks.
