WIDIA ISO turning inserts and matched tooling
Compare WIDIA CCMT-MU, CNMG-UM, DCMT-MU, DNMG-MU and WNMG-UM turning insert groups with external toolholders, boring bars and replacement parts. Use the exact material-number row to compare grade, corner radius and dimensions, then follow its verified component references.
Match the insert to its seat and clamping system
Start with the exact WIDIA insert article and its listed holder relationships. Verify insert size, thickness, corner radius and cutting hand against the chosen toolholder. A similar designation or nominal size does not establish the same seat or clamping arrangement.
Check the machine interface and working dimensions
For external holders, compare shank height, width and working dimensions with the machine setup. For boring bars, review shank diameter, minimum bore and dimensions supplied for the selected article. Keep native inch and metric configurations separate.
Identify the replacement component
Use the holder’s component references for replacement screws, clamps, pins, seats and keys. Include the exact service article and parent holder in your quote request. Review the relevant original technical reference where linked on the product page; appearance alone does not establish fit.
Frequently asked questions
Can I request an insert, holder and replacement parts together?
Yes. Choose each exact configuration and quantity, add the components to Quote, and send one request to Tech Tool.
What information helps identify a replacement?
Include the full catalog designation, material number and quantity. Add the existing holder or insert article and workpiece material when you need selection assistance.
