Use Guide
Confirm the fit
Check diameter, bore and segment dimensions against the table above and against your machine.
Set the parameters
Start at the machine builder's figures for your material, then adjust feed until the cut runs quiet and the surface stays clean.
Keep it free-cutting
If the tool stops cutting and the face goes shiny, it has glazed. Dress it, then tell us — that means the bond should change.
