Superior Rigidity: Straight flute structure resists high cutting forces, high-precision threads, no secondary processing

Efficient Chip Evacuation: Short chips discharged smoothly, preventing clogging and tap breakage

High-Speed Machining: Higher cutting parameters than standard taps, improving productivity

Versatile Application: Suitable for through holes & blind holes, ideal for mold, aerospace, automotive and heavy industry

Applications

Mold Manufacturing：Thread machining for hardened steel mold components, ensuring assembly precision and structural integrity

Aerospace：High-strength steel components for aircraft structures, engines and landing gear, with high-reliability precision threads

Automotive Engineering：Hardened steel parts for engines, transmissions and suspensions, stable and durable

Heavy Machinery Equipment：Threaded connections for high-hardness steel components in heavy machinery, long life and high stability

Hot Q&A

Can it be used for materials other than high-hardness steel?

Answer: Optimized for HRC60+ high-hardness steel; compatible with other metals of similar hardness. For best performance and tool life, use material-specific taps.

How to prevent taps from breaking?

Answer: Match cutting speed and feed rate to steel hardness and tap specifications; use appropriate cutting fluid; regularly clean chips from flutes; inspect for wear before each use.

What is the difference between straight-slot taps and helical-slot taps in the processing of high-hardness steel?

Answer: Straight flute taps offer higher rigidity, ideal for through holes and materials producing short chips. Spiral flute taps excel at evacuating long chips, preferred for soft materials or blind holes (not for high-hardness steel).
