FAQ for carbide threading inserts
Add these questions to the collection page to capture long-tail search traffic and guide buyers toward inquiry.
What is the difference between full-profile and partial-profile threading inserts?
Full-profile inserts are designed for a specific pitch and can finish the crest and thread form in one operation. Partial-profile inserts cover a pitch range but usually require additional control of the thread crest diameter.
When should I choose thread whirling inserts instead of thread turning inserts?
Thread whirling is often preferred for long, slender or deep-profile threads such as worm shafts, medical bone screws, implants and lead screws, especially when productivity and profile accuracy are critical.
Can ONMY make custom threading inserts from a drawing or sample?
Yes. Provide the thread profile drawing, pitch or lead, start number, hand direction, workpiece material, machine model and current tooling problem. ONMY can review the geometry and recommend a custom carbide insert solution.
Which coating should I use for threading inserts?
Coating depends on workpiece material, cutting speed, coolant condition and tool life target. PVD coatings are commonly used for sharp edges and precision profiles, while CVD coatings may be selected for higher wear resistance in heavier cutting.
Need a special thread profile or whirling insert?
Send your drawing, sample photo, machine model and machining problem. ONMY can help review the insert geometry, carbide grade, coating and cutting edge preparation.
