Threading tools FAQ
Answers to common questions about threading inserts, thread whirling tools, holders and custom carbide tooling.
What is the difference between threading inserts and thread whirling inserts?
Threading inserts are usually used for single-point internal or external thread turning. Thread whirling inserts work in a whirling head and are often used for long, deep or special thread profiles such as worm shafts, bone screws and lead screws.
Can ONMY make custom threading tools from drawings?
Yes. ONMY can review part drawings, thread profiles, current insert samples, machine information and tooling problems to provide custom carbide threading tools or inserts.
Which page should I visit for standard thread inserts?
For standard thread turning inserts, visit the Precision Carbide Threading Inserts page. It includes ISO, UN, ACME, TR, Buttress, API, NPT, BSPT and other insert series.
Which page should I visit for worm shafts or medical bone screws?
For worm shafts, bone screws, lead screws and other special profiles, start with the Thread Whirling Inserts range or select the relevant application above.
