The OSG Metric Spiral Point Threading Tap is a precision tool designed for through-hole metalworking, built for professionals who demand consistent, accurate threads and reliable performance.
- Material: HSS-E (high-speed steel with cobalt) for enhanced hardness and heat resistance during demanding cuts.
- Coating: Steam oxide coating provides wear resistance and smoother cutting action, extending tool life.
- Threading design: Metric spiral point geometry directs chips forward for efficient evacuation and cleaner thread formation.
- Size: M42 x 4.5, a large-diameter thread ideal for robust through-hole applications.
- Application: Specifically engineered for through-hole threading, delivering consistent pitch and accurate thread profiles.
This tap is crafted to handle tough materials and high-speed cutting scenarios without sacrificing thread quality. The cobalt-enhanced HSS substrate maintains sharpness longer under heat, while the steam oxide coating reduces friction and wear, helping to minimize built-up edge. The spiral point design accelerates chip clearance, which translates to smoother operation and fewer interruptions in threaded hole production. Ideal for machine shops, maintenance teams, and fabrication work that requires dependable, repeatable large-thread taps.
