The OSG Metric Spiral Flute Threading Tap is built for precise, reliable M3 x 0.5 internal threads in blind holes. Designed for machinists and engineers who demand consistent quality, this tap combines durability with efficient cutting in confined spaces.
- Size & pitch: M3 x 0.5 metric threading for small-diameter blind-hole applications
- Material: HSS-E (high-speed steel with cobalt) for enhanced heat resistance and wear durability
- Coating: Titanium Nitride (TiN) coating to extend tool life and reduce friction
- Flute design: Spiral flute geometry optimized for effective chip evacuation in deep blind holes
- Application: Specifically suited for internal threading in tight or hard-to-reach cavities
- Brand: OSG threading tap, a trusted choice for precision metalworking
This tap delivers clean, accurate threads with steady performance, even under demanding tapping tasks. The TiN coating reduces wear and heat buildup, helping maintain thread quality across multiple holes. The spiral flute design minimizes chip packing, lowering the risk of binding and ensuring smoother operation in blind-hole scenarios. Ideal for production environments and meticulous prototypes alike, it supports reliable fastener fit and long tool life.
