Thread Whirling Inserts
Custom carbide thread whirling inserts for worm shafts, medical bone screws, lead screws, rotors and special thread profiles. ONMY supports profile design, carbide grade selection, coating, edge preparation and insert manufacturing from drawings or samples.
Thread whirling inserts for difficult thread profiles
Thread whirling is often selected when the part has a long thread, deep profile, slender workpiece, difficult material or special thread form that is not efficient with ordinary single-point turning.
Profile accuracy
Ground 硬質合金刀片 are designed around the thread form so the final thread profile can be controlled more consistently.
High productivity
The whirling process is suitable for efficient machining of long threads and special profiles on Swiss-type and CNC machines.
Custom geometry
Insert width, flank angle, rake face, clearance, chip control and helix compensation can be customized for the workpiece.
Material matching
Carbide grade, polished edge, PVD coating and edge preparation are selected according to titanium, stainless steel, alloy steel or other materials.

The most valuable inquiry for this page is not a standard insert inquiry. It is a customer sending a thread drawing, current insert sample, whirling head information or machining problem.
Best files to send
Thread profile drawing, workpiece drawing, material, machine model, whirling head, insert pocket size, current insert photo and the problem you want to solve.
Send files to ONMYThread geometry
Profile type, pitch or lead, starts, left-hand or right-hand direction, major diameter, minor diameter and thread depth.
Part and material
Workpiece material, hardness, heat treatment, required surface finish, burr control and batch size.
Machine information
Swiss-type lathe or CNC machine model, whirling head brand, insert pocket, toolholder and coolant condition.
Insert solution
ONMY reviews carbide grade, edge preparation, rake and clearance angles, coating and inspection requirements.
Thread whirling vs thread turning
This comparison helps buyers understand when to choose whirling inserts instead of ordinary single-point threading inserts.
| Requirement | Thread whirling inserts | Thread turning inserts |
|---|---|---|
| Long and slender parts | Often better because cutting can happen near the guide bush and reduce deflection risk. | May create radial force and deflection on slender parts. |
| Deep or special profiles | Custom profile inserts can reproduce complex thread forms efficiently. | May require multiple passes and careful toolpath control. |
| Medical bone screws | Suitable for titanium screws, implants and asymmetrical profiles when insert geometry is designed correctly. | Useful for simpler threads or low-volume trials, but may struggle with deep medical profiles. |
| Worm shafts and lead screws | Good option for long threads, multi-start threads and special profiles. | Still useful for small batches, repair work or less demanding profiles. |

Can ONMY make custom thread whirling inserts from a drawing?
Yes. Send the thread profile drawing, workpiece drawing, material, pitch or lead, starts, hand direction, machine model and whirling head information. A current insert sample or photo is also helpful.
What parts are suitable for thread whirling inserts?
Typical parts include worm shafts, medical bone screws, implant screws, lead screws, feed screws, rotors, micro screws and other parts with long or special thread profiles.
How is a whirling insert different from a standard threading insert?
A standard threading insert is usually used for single-point turning. A whirling insert works in a rotating whirling head and often needs custom profile geometry, helix compensation and material-specific edge preparation.
Which information affects tool life?
Workpiece material, hardness, cutting speed, coolant, coating, edge preparation, machine rigidity and the accuracy of the insert profile all affect tool life and finished thread quality.
Need custom thread whirling inserts?
Send your part drawing, thread profile, machine model and current tooling issue. ONMY can review the insert geometry, carbide grade, coating and edge preparation.
