OSG Threading Tap - Metric Spiral Point HSS-E - Steam Oxide Coated Plus - Through Hole - M4 x 0.7

The OSG Metric Spiral Point Threading Tap is a precision tool for through-hole metal tapping, built for machinists who demand reliable, consistent threads. Crafted from HSS-E cobalt and finished with Steam Oxide Coated Plus, it delivers durable performance and superior heat resistance for everyday tapping tasks.

• Size & pitch: M4 x 0.7 through-hole threading tap, optimized for metric threads in through-hole applications
• Material: High-speed steel with cobalt (HSS-E) for enhanced hardness and wear resistance
• Finish: Steam Oxide Coated Plus to reduce friction, improve chip flow, and extend tool life
• Geometry: Spiral point design to push chips ahead and promote clean, accurate thread formation in through-holes
• Application focus: Specifically suited for through-hole tapping in metal workpieces, delivering consistent thread quality across production runs

With this tap, you gain dependable performance from the first cut to the final thread: precise M4 x 0.7 threads, fewer interruptions from chip buildup, and extended tool life thanks to the HSS-E cobalt composition and protective oxide finish. It’s ideal for production environments, automotive components, enclosure fabrication, and general machining where fast, reliable through-hole threading matters. For best results, use proper lubrication and appropriate tapping speeds to maximize thread quality and tool longevity.
