Compatibility and use
How do I order a replacement A-MDUN 93° holder?
Use the exact material number and complete catalog designation. For example, 1098102 identifies A25RMDUNR15. 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.
