01/11/2022 Q: What is the expected tip life for an on-car lathe?
A:
The geometry and composition of the Pro-Cut tips are designed for °single pass° cutting. When using the Pro-Cut the cutting depth should be set to take all material needed to get below rust grooves, eliminate all run-out and resurface the entire disc in a single pass. Cuts of 0.1016-0.381 mm (0.004-0.015 in) will provide the best surface finish and the optimal tip life. No °skim cut° or °finish cut° is needed. Failure to follow this procedure will shorten tip life. The Pro-cut tips will last between 7-12 cuts per corner. With three usable corners, a pair of tips is good for at least 21 cuts.
