Description
The OSG Metric A-OIL-Spiral Flute Tap is a high-performance threading tool designed for precision work in blind holes. Built for professionals demanding reliability in demanding production environments, it delivers consistent, high-quality threads from tough materials.
- Material: Powder metal construction delivers robust strength and durability for repeated tapping in hard metals and deep blind holes.
- Coating: TiCN coating increases hardness and wear resistance while reducing friction to extend tool life.
- Flute Design: A-OIL spiral flute optimizes chip evacuation, promoting smoother cutting and reducing the risk of clogging in deep or blind holes.
- Thread Type: Metric size M52 x 5, designed to DIN 376 specifications for accurate, repeatable threads in blind-hole applications.
- Orientation: Right-hand threading aligns with common machining setups to produce standard external threads reliably.
- Application: Specifically engineered for blind-hole threading in demanding production environments where precision and longevity matter.
This combination of powder metal toughness, TiCN wear resistance, and efficient chip evacuation means cleaner threads, fewer tool changes, and longer tool life. The tap maintains cutting performance under high feed rates and extended cycles, helping you achieve consistent hole quality and reduced downtime in automotive, aerospace, and general manufacturing contexts.
