Precision threading tap built for through-hole applications, the OSG Metric Spiral Point Threading Tap delivers reliable, high-quality threads with efficient chip evacuation. Designed for machinists who value accuracy, durability, and productivity in metalworking.

• Material and coating: High-Speed Steel with cobalt (HSS-E) for superior hardness and heat resistance, finished with a steam oxide coating to reduce wear and corrosion.
• Threading geometry: Spiral point design facilitates fast, continuous cutting and effective chip evacuation for clean, accurate M11 x 1.5 threads in through-hole workpieces.
• Size and application: Metric thread size M11 x 1.5, optimized for through-hole tapping in a range of metals, delivering consistent thread depth and fit.
• Durability: Cobalt-enhanced HSS-E combined with steam oxide chemistry extends tool life in demanding tapping operations and high-temperature environments.

The combination of HSS-E with cobalt content and a steam oxide finish provides a robust tapping solution that maintains edge sharpness and resists heat buildup. The spiral point geometry helps push chips ahead of the cutting edge, reducing clogging and enabling smoother, more reliable threading cycles. Through-hole compatibility ensures consistent thread depth and engagement, making this tap ideal for production runs, aerospace and automotive fixtures, and precision jigs where repeatable M11 x 1.5 threads are required. For machinists seeking durable tooling that minimizes rework and downtime, this OSG tap offers dependable performance and long tool life in everyday metalworking tasks.
