OSG Metric Spiral Flute Threading Tap is built for precision metalworking in blind-hole applications. Crafted for professionals who need reliable, repeatable metric threads, it combines durability with efficient chip evacuation for consistent results.

• Size & Thread: M12 x 1.75 metric threading for standard fastener compatibility and accurate pitch control.
• Material: HSS-E (high-speed steel with cobalt) for enhanced hot hardness and wear resistance during demanding threading tasks.
• Coating: Steam oxide coating to reduce friction, improve heat resistance, and extend tool life in challenging cuts.
• Flute Design: Spiral flute geometry tailored for efficient chip removal in blind-hole work, helping prevent chip buildup and heat buildup.
• Application: Specifically optimized for threading inside blind holes, delivering clean, consistent threads across a range of metals.
• Durability: Robust construction designed for repeated use in precision machining without rapid wear.

With the OSG Threading Tap, you gain predictable, high-quality threads and improved longevity on critical projects. The HSS-E composition paired with the steam oxide finish reduces wear and thermal stress, while the spiral-flute geometry keeps chips moving away from the cutting edge for smoother operation. This combination supports steadier performance, fewer tool changes, and better overall productivity in professional machining environments.
