The OSG Metric Spiral Point Threading Tap in M39 x 4 is a precision tapping tool designed for through-hole work in metalworking applications. Crafted from HSS-E with cobalt and finished with a steam oxide coating, it delivers durability, heat resistance, and reliable threading performance in demanding environments.

• Thread size: M39 x 4 metric spiral point threading tap designed for through-hole applications
• Material: HSS-E (high-speed steel with cobalt) for extended cutting life and better performance at elevated temperatures
• Coating: Steam oxide coating to reduce friction and provide corrosion resistance
• Design: Spiral point enables efficient chip evacuation and clean, straight threads in through-holes
• Application: Specifically optimized for through-hole tapping, promoting consistent thread quality and longer tool life in tough materials

This combination of cobalt-enhanced HSS-E, a steam oxide finish, and a spiral point geometry helps maintain sharpness, lowers heat buildup, and minimizes chip clogging. It’s an ideal choice for high-precision M39 x 4 threads in through-hole components, delivering dependable performance and reducing downtime in your machining workflow.
