Choosing a configuration
Compatibility and use
How do I order a replacement MDJN -3° holder?
Use the exact material number and complete catalog designation. For example, 2953464 identifies MDJNR124B. 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.
