The OSG UNC A-Spiral Flute Threading Tap is a high-performance tool engineered for tapping UNC threads in blind holes with reliability and precision. Made from a durable powder metal core and TiCN-coated for extended life, it delivers consistent results in demanding machining environments.

• Thread Type: UNC A (Unified National Coarse) threads for versatile compatibility with standard fasteners and common materials.
• Flute Design: A-Spiral flute promotes efficient chip evacuation in blind holes, helping maintain smooth cutting and reduce stoppages.
• Material: Powder metal construction provides exceptional strength, toughness, and wear resistance under challenging tapping conditions.
• Coating: TiCN coating increases hardness, lowers friction, and improves cutting performance at higher speeds for longer tool life.
• Working Direction: Right-hand threading aligns with conventional fastener systems and typical machining setups.
• Size and Standard: 5/8-11 UNC size, DIN2184-1 compliant for reliable blind-hole tapping in standardized assemblies.
• Application: Specifically designed for blind holes, enabling clean thread formation even where chip clearance is limited.

The combination of a robust powder-metal core, TiCN coating, and an optimized A-spiral flute translates into durable performance, cleaner threads, and fewer tool changes during production. This tap is ideal for shops that regularly work with standard UNC fasteners in steels and alloys, delivering dependable results in demanding blind-hole applications without compromising precision.
