Description
The OSG Metric A-LT-Spiral Flute Threading Tap is a high-performance tool designed for precise metric threading in blind holes. Built for machinists and fabrication shops, it combines durable powder-metal construction with a TiCN coating to deliver reliable, long-lasting performance.
- Series: A-LT-Spiral Flute
- Material: Powder metal construction for high strength and durability
- Coating: TiCN coating for increased hardness and wear resistance
- Flute configuration: LT (Long-Taper) Spiral Flute to facilitate superior chip evacuation in deep blind holes
- Thread direction: Right-hand threading
- Size: Metric M8 x 1.25
- Application: Specifically designed for threading in blind holes
Designed to tackle demanding blind-hole threading tasks, this tap helps maintain clean, accurate threads even in deep cavities. The LT spiral flute minimizes chip buildup and cutting forces, reducing the risk of tap fatigue and breakage. TiCN coating enhances surface hardness and dramatically lowers friction, extending tool life and supporting efficient high-speed machining. Expect consistent thread quality, better surface finishes, and reduced downtime in production environments.
