- Size and standard: M56 x 5.5 metric tap designed for blind-hole threading, DIN 376 compliant.
- Material: Powder metal body for high strength and durability under heavy machining conditions.
- Coating: TiCN coating enhances hardness and wear resistance, reducing tool wear and extending life.
- Flute design: A-OIL spiral flute optimized for chip evacuation in deep or blind-hole applications, promoting smoother cuts.
- Direction: Right-hand threading to align with standard machining practices.
- Application: Specifically engineered to deliver clean, accurate threads in blind holes for dependable assemblies.
Designed to tackle challenging blind-hole threading with confidence, this tap combines robust powder-metal construction, a hard-wearing TiCN coating, and an efficient A-OIL spiral flute. The result is improved chip evacuation, reduced binding, and longer tool life—benefits that translate into higher throughput and more consistent thread quality across production runs. Ideal for metalworking shops and precision manufacturers where durable tooling and reliable performance matter most.
