The OSG Metric Spiral Flute Threading Tap is a precision tool designed for machinists who need reliable, accurate threads in blind-hole applications. Built with cobalt-enhanced HSS-E and a steam oxide coating, it delivers durable performance and steady heat resistance for demanding tapping tasks.
- Thread type: Metric spiral flute threading tap designed specifically for blind holes
- Material: HSS‑E (high‑speed steel with cobalt) for superior hardness and wear resistance
- Coating: Steam oxide coating to reduce friction and extend tool life
- Size: M4 x 0.7 thread specification for standard metric fits
- Flute design: Spiral flutes optimize chip evacuation and help maintain cutting stability in limited-depth holes
- Application: Ideal for precision threading in metal parts where access is restricted to blind holes
With this tap, you can expect consistent thread form and clean finishes in tight spaces. The combination of HSS‑E material and steam oxide coating minimizes heat buildup and wear, promoting longer tool life and more reliable performance across multiple production runs. The spiral flute geometry enhances chip removal, reducing the risk of clogging and chatter, so you achieve precise, repeatable threads in your most critical machining tasks.
