Description
The OSG RC threading tap for BSPT in A-Spiral Flute design is built for professionals who demand dependable, precise BSPT threads in blind-hole applications. With a TiCN coating and powder metal construction, this tap is engineered for durability and consistent performance in challenging materials.
- Threading Type: RC (BSPT) with right-hand threads designed for British Standard Pipe Taper applications.
- Flute Design: A-Spiral flute enhances chip evacuation in both blind-hole and through-hole tapping, reducing clogging and improving finish.
- Material: Powder metal construction delivers excellent wear resistance, toughness, and long tool life in demanding jobs.
- Coating: TiCN coating increases heat resistance and lowers friction for faster cutting speeds and extended tool life.
- Hole Type: Optimized for blind holes, providing reliable entry and stable threading even with restricted access.
- Size: 3/8 x 19, suitable for common BSPT specifications and DIN5156 standards.
- Finish and Precision: High-precision geometry paired with durable coating ensures consistent thread form and dimensional accuracy.
This tap is designed to deliver reliable, precise results in production or shop-floor environments where BSPT threads must meet tight tolerances in blind-hole contexts. The combination of powder metal toughness, TiCN wear resistance, and an efficient spiral flute supports higher throughput, reduces tool changes, and minimizes scrap while maintaining accurate BSPT thread engagement.
