OSG Threading Tap NPSF A-Spiral Flute - FORME Powder Metal Right Hand -TiCN Coated - Blind Holes DIN5156 - 1/2 x 14

The OSG NPSF A-Spiral Flute threading tap is a high-precision tool designed for blind-hole applications, delivering dependable National Pipe Straight Fuel threads with clean, consistent results.

• Thread Type: NPSF (National Pipe Straight Fuel) threads tailored for precise engagement in blind holes.
• Flute Design: A-Spiral Flute aids rapid chip evacuation and minimizes clogging for smoother cutting in restricted workspaces.
• Substrate: FORME powder metal construction for exceptional wear resistance and durability in demanding cutting conditions.
• Coating: TiCN coating enhances heat resistance and reduces friction, extending tool life and enabling stable cutting speeds.
• Thread Direction: Right-hand threading for standard assembly and reliable nut-into-thread performance.
• Hole Type: Optimized for blind holes, ensuring accurate depth control and clean thread formation.
• Size / Pitch: 1/2 x 14, suitable for a common NPSF specification used in many hydraulic and pneumatic components.
• DIN Standard: Designed to DIN 5156 specifications, supporting compatibility with compatible tooling and assemblies.

This tap delivers practical, repeatable results in metal components where space is limited and clean, leak-tight NPSF threads are essential. The A-Spiral flute design helps manage chip flow in blind-hole environments, reducing the risk of extraction damage and improving surface finish on threaded sections. The combination of FORME powder metal and TiCN coating provides a robust tool life that stands up to higher-speed machining and tougher materials, making it a reliable choice for professional machinists, automotive technicians, and hydraulic engineers seeking precise, durable threading performance.
