OSG Threading Tap NPT A-Spiral Flute - Powder Metal Right Hand -TiCN Coated - Blind Holes DIN5156 - 1/16 x 27

The OSG Threading Tap NPT A-Spiral Flute is a high-performance tapping tool designed to cut National Pipe Taper (NPT) threads in blind-hole applications. It’s built for machinists and fabricators who need durable, precise threads in tight spaces, delivering reliable results with every cut.

• Thread Type: National Pipe Taper (NPT) threads for blind-hole tapping and leak-free seals.
• A-Spiral Flute Design: Special spiral flutes promote efficient chip evacuation, reducing clogging in blind holes and improving thread quality.
• Material: Powder metal construction offers enhanced durability, wear resistance, and toughness in demanding materials.
• Coating: TiCN coating provides superior heat resistance and reduced friction for faster cutting speeds and longer tool life.
• Size: 1/16" nominal diameter with 27 threads per inch (1/16-27 NPT).
• Orientation: Right-hand threading compatible with standard NPT fittings and DIN 5156 blind-hole applications.
• Application: Ideal for precision threading in metal workpieces where a blind hole must be tapped to accept NPT fittings.

These features combine to deliver accurate thread profiles, reduced tool wear, and longer service life in tough materials. The spiral flute design minimizes chip buildup in confined blind-hole environments, while the TiCN coating helps maintain cutting efficiency across multiple uses. For technicians working with hydraulics, pneumatics, and fluid connections, this tap supports quick, repeatable results and clean, seal-tight threads, even in restricted spaces.
