Description
The OSG UNC A-Spiral Flute threading tap is built for high-precision tapping in blind holes, delivering reliable performance in production and repair environments. With a powder metal body and TiCN coating, it combines durability with smooth cutting for UNC A threads (9/16" diameter, 12 TPI).
- Size & Thread: 9/16" nominal diameter, UNC A (12 TPI), right-hand thread
- Material: Powder metal construction for enhanced toughness and wear resistance
- Coating: TiCN coating increases hardness, reduces friction, and extends tool life
- Flute Design: A-sp spiral flute aids efficient chip removal in blind-hole applications
- Application: Specifically designed for tapping UNC threads in blind holes; DIN2184-1 compliant
This tap is optimized for fast, clean cuts with minimal chatter, allowing for consistent thread quality in challenging blind-hole geometries. The combination of powder metal durability and TiCN coating means fewer tool changes and reduced downtime in demanding machining schedules.
