Description
The OSG Metric A-OIL-Spiral Flute threading tap is built for precision in blind-hole threading, ideal for demanding production environments that require reliable, long-lasting tooling. This right-hand tap features a TiCN-coated, powder-metal body and a DIN 376 specification for M20 x 2.5 threads.
- Threading Type: Metric A-OIL-Spiral Flute design optimized for efficient chip evacuation in blind holes; right-hand cutting direction.
- Size & Standard: M20 x 2.5 threads, conforming to DIN 376 for consistent compatibility with related taps.
- Material: Powder metal body delivering robust strength and fatigue resistance in challenging drilling and threading tasks.
- Coating: TiCN coating enhances hardness and wear resistance while reducing friction to extend tool life.
- Flute Design: A-OIL spiral flutes promote smooth chip flow, minimizing clogging in deep or blind-hole applications.
- Application: Specifically suited for blind-hole threading in high-performance settings where precision and durability matter.
This combination of material, coating, and flute geometry translates to cleaner threads, less tool wear, and fewer tool changes in production runs. Operators benefit from stable performance, consistent thread quality, and longer intervals between re-sharpening or replacements, making it a dependable choice for precision assemblies and high-throughput manufacturing.
