Technical guidance & FAQs

Applications and materials

WIDIA A-PWLN 95° Boring Bars for internal turning and boring. Select the exact holder material number and its manufacturer-listed insert configuration as a matched system.

Choosing a configuration

For A32SPWLNR08 (article 3883454), check Tool length L1 (mm): 250; F dimension (mm): 22. Compare the selected configuration’s shank, working dimensions and overall length with your machine setup. Use the exact material number when requesting a replacement.

Compatibility and use

Manufacturer-listed insert designations in this selected system include WNMG080404UM, WNMG080408UM, WNMG080412UM. Use the exact insert-to-holder match for the selected material number. A family designation alone does not confirm the seat, clamping components or cutting hand.

How do I order a replacement A-PWLN 95° holder?

Use the exact material number and complete catalog designation. For example, 3883454 identifies A32SPWLNR08. Confirm the selected shank and length against the existing setup before choosing an alternative.

Are inserts and service parts interchangeable across this family?

Use the manufacturer-listed pairing for the exact holder article. Confirm the insert seat and replacement screw, clamp, shim or key individually; a similar-looking component or matching insert shape does not establish compatibility.
