Description
The OSG Threading Tap NPSF A-Spiral Flute is a precision tool built for professionals who need accurate NPSF threads in blind-hole applications. Crafted with FORME powder metal and a TiCN coating, it offers lasting durability and efficient cutting performance for demanding materials.
- Size: 3/4" diameter with 14 TPI, designed for NPSF threads in blind holes
- Thread Type: NPSF (National Pipe Straight Fuel) threads following DIN5156 standards
- Flute Design: A-Spiral flute aids in continuous chip evacuation for smoother operation
- Material: FORME powder metal substrate delivers enhanced wear resistance
- Coating: TiCN coating reduces friction and improves heat resistance for longer tool life
- Application: Right-hand threading specifically suited for blind-hole installations with reliable results
This combination of robust substrate, efficient chip management, and a hard-wearing coating translates to consistent, high-quality thread formation. The tool is ideal for meticulous threading tasks in assemblies where NPSF connections must be secure and leak-tight, and where blind holes are required by design. The right-hand orientation ensures compatibility with standard installation practices, while the DIN5156 specification supports precise, repeatable results across compatible components.
