Engineered for precision internal threading in blind-hole work, the OSG Metric Spiral Flute Threading Tap (M3 x 0.5) delivers reliable, long-lasting performance for metalworking projects where clean, accurate threads are essential.

• Material: HSS-E (high-speed steel with cobalt) for superior hardness and heat resistance
• Finish: Steam Oxide Coated Plus to reduce friction, resist wear, and extend tool life
• Flute design: Metric spiral flute optimized for effective chip evacuation in blind holes
• Thread size: M3 x 0.5 pitch for standard metric internal threading
• Application: Specifically designed for blind-hole tapping; suitable for hand or machine tapping with proper lubrication
• Durability: Robust construction and coating withstand demanding machining conditions while maintaining thread quality

This tapping solution helps you achieve precise, burr-free internal threads with consistent results across production runs. The spiral flute promotes efficient chip removal in confined blind-hole environments, reducing the risk of clogging and tool breakage. The cobalt-infused HSS-E base combined with the Steam Oxide Coated Plus finish minimizes heat buildup and wear, delivering extended tool life and dependable performance from start to finish. Ideal for small-diameter applications in steel, aluminum, and other common metals, it supports reliable threaded joints in automotive, electronics, and general fabrication work.
