Learn more about Klarna
Description
The OSG Threading Tap - Metric Spiral Point HSS-E with TiN coating for Through-Hole M8 x 1.25 is a precision tool designed for professionals who need fast, accurate internal threads in through-hole components. Made from HSS-E cobalt with a Titanium Nitride coating, it delivers durable performance and extended tool life.
- Material: HSS‑E (high‑speed steel with cobalt) for enhanced strength and wear resistance
- Coating: Titanium Nitride (TIN) coating to reduce friction and extend tool life
- Threading design: Metric spiral point geometry for efficient chip evacuation and smooth threading in through-holes
- Size and pitch: M8 x 1.25 thread size with through‑hole capability
- Application: Optimized for internal threading in through-hole components, offering reliable performance in metalworking projects
- Precision engineering: OSG’s meticulous manufacturing delivers accurate thread form and repeatable results
This tap helps you achieve clean, accurate threads with minimal rework, thanks to the spiral point that pushes chips forward and reduces clogging. The hardened HSS‑E cobalt core maintains sharpness longer, while the TiN coating lowers friction and wear across extended use, enabling more jobs to be completed with a single tool. It’s well suited for workshops and maintenance tasks requiring reliable internal threads in through-holes, whether in a CNC setup or hand tapping. For best results, use proper cutting fluid, stable workholding, and steady, even feeding to maximize tool life and reduce the risk of breakage.
