The OSG Threading Tap NPT A-Spiral Flute in a powder metal body is a precision internal/threading tool designed for creating 1/4-18 NPT threads in blind holes. Built for professional use, it delivers reliable, clean taps in challenging applications.

• Flute Style: A-Spiral Flute design enables efficient chip evacuation in blind holes, helping prevent clogging and reducing tap stress.
• Material: Powder Metal body delivers high toughness, wear resistance, and durability for demanding materials and repeated use.
• Coating: TiCN coating provides excellent heat resistance and lower friction, supporting faster cutting speeds and longer tool life.
• Thread Type & Size: NPT (National Pipe Taper) threading at 1/4-18, designed for precise taper threads in pipe connections.
• Application: Optimized for blind-hole tapping and aligned with DIN5156 specifications for reliable, repeatable results.
• Hand: Right-hand tapping to produce standard internal threads.

These taps empower you to achieve accurate, leak-free NPT threads in hard-to-reach blind holes, improving assembly reliability and reducing retapping needs. The spiral flute minimizes chip buildup and binding, while the TiCN coating lowers friction and dissipates heat, enabling efficient machining and extended tool life across a range of materials and applications.
