The OSG Threading Tap NPT A-Spiral Flute is a purpose-built tool for creating National Pipe Taper (NPT) threads in blind holes. Designed for machinists and fabricators who demand precision and durability, this TiCN-coated, powder metal tap delivers reliable internal threads in challenging materials.
- Thread Type: NPT (National Pipe Taper) threads designed for leak-tight connections in blind-hole applications.
- Flute Design: A‑spiral flute for efficient chip evacuation and reduced risk of clogging during deeper or blind-hole tapping.
- Material: Powder metal construction provides strong wear resistance and toughness in demanding cutting conditions.
- Coating: TiCN coating reduces friction and improves heat resistance, enabling smoother cuts and longer tool life.
- Orientation: Right-hand cutting direction for standard internal threading operations.
- Size: 3/4 x 14 NPT, a common size for industrial piping and hydraulic fittings.
- DIN Standard: Compatible with DIN5156 blind-hole threading requirements for consistent, dependable results.
This tap supports precise, repeatable threading in a variety of materials, making it well-suited for hydraulic, pneumatic, and mechanical assemblies that require robust NPT connections in confined spaces. The combination of spiral flutes, powder metal durability, and TiCN coating helps maintain cutting efficiency, reduce tool wear, and extend service life even when tapping into tough substrates.
