Description
The OSG Threading Tap NPSF A-Spiral Flute is a precision right-hand tap designed to cut National Pipe Straight Fuel (NPSF) threads in blind-hole workpieces. Built on FORME powder metal and finished with TiCN coating, it blends durability with high cutting performance for demanding applications.
- Thread type: NPSF (National Pipe Straight Fuel) threads for blind-hole applications
- Flute design: A-Spiral flute promotes efficient chip evacuation to minimize clogging and stabilize cutting
- Material: FORME powder metal body delivers excellent wear resistance and long tool life
- Coating: TiCN coating reduces friction, improves heat resistance, and extends usable life
- Right-hand construction: Right-hand threading as standard for common NPSF tapping work
- Size: 1/8" diameter with 27 TPI (1/8 x 27)
- Standards: DIN5156 compliance ensures compatibility with standard NPSF engagements
- Applications: Suitable for threading in a variety of materials inside blind holes
This tap delivers precise, clean NPSF threads with reliable finishes, improved chip control, and longer tool life thanks to the combination of FORME powder metal durability and the low-friction TiCN coating. It’s an effective choice for production runs or service work where accurate blind-hole threads are essential.
