Ask an engineerTool selection depends primarily on the type of hole you are tapping:
Tap breakage is usually caused by inadequate chip evacuation, improper hole sizing, or misalignment. To optimize process reliability, ensure that:
For stainless steel (such as 304/316) and other gummy materials, standard HSS taps wear out rapidly. JIAYI SEIKO recommends high-vanadium high-speed steel (HSSE-V3) or powder metallurgy cobalt HSS substrate, paired with TiAlN or CrN coatings. These advanced coatings offer exceptional heat resistance and low friction coefficients, effectively preventing built-up edge (BUE) and significantly extending tool life.
Yes. We offer comprehensive OEM/ODM engineering services for non-standard threading applications. Whether you need custom thread profiles (e.g., specific pitch combinations, acme threads, multi-start threads), special tolerance classes (such as oversized/undersized GH limits), or extended shank lengths for hard-to-reach areas, our technical team can design and deliver the exact blueprint you need.
