The OSG Threading Tap is a precision instrument designed for professional metalworking, delivering reliable M11 x 1.5 threads in blind holes with a spiral flute for efficient chip evacuation.

• Substrate: HSS-E (high-speed steel with cobalt) for enhanced wear resistance and heat tolerance.
• Coating: Steam oxide coating to boost lubricity and corrosion resistance, helping extend tool life.
• Flute design: Spiral flute geometry that facilitates smooth cutting and efficient chip evacuation in blind-hole applications.
• Thread size: Metric M11 x 1.5 threading capability for common metalworking needs.
• Application: Specifically optimized for blind-hole tapping, delivering consistent, clean threads even in restricted depths.

The combination of HSS-E alloy, steam oxide surface, and spiral-flute geometry translates into longer tool life, better thermal performance, and dependable thread quality across multiple holes. It’s a practical choice for production runs, repair work, and any job where repeatable, accurate M11 x 1.5 threads in blind holes are required.
