The OSG Threading Tap NPSF A-Spiral Flute is a right-hand tap engineered for National Pipe Straight Fuel (NPSF) threads in blind-hole applications. Built on FORME powder metal with a TiCN coating, it delivers durable performance and reliable, clean thread formation.

• Tap Type: Right-hand threading tap for NPSF threads in blind holes
• A-Spiral Flute: Spiral flute design enhances chip evacuation and reduces risk of clogging in blind-pocket work
• Material: FORME powder metal for superior wear resistance and long tool life
• Coating: TiCN coating increases hardness, lowers friction, and improves heat resistance
• Thread Standards: DIN5156 compliant NPSF threads designed for precise blind-hole applications
• Size: 1/16" diameter x 27 TPI for compact, accurate threading

The combination of FORME powder metal and TiCN coating translates to sustained performance even in tougher materials, with smoother cutting action and less tool chatter. The A-Spiral flute aids chip control, enabling consistent thread quality and reducing maintenance downtime from plug-ups in restrictive blind-hole environments.
