It is hard on the carbide tip when it gets to the slot and back onto the rotor. Sometimes the carbide tip breaks or skips on the rotor. Many places will not turn your rotor because of this. Carbide tips are not cheap. Allen Here's a novel idea, let's not throw a bunch of parts at the car hoping it will fix the problem and instead spend a little time diagnosing it first. Life was a little easier when I was just a wrench.

Seems to me the slots/ holes in a vented rotor would be deadly to tools, unless you have a grinder, and few shops do. Grinding them would take a LONG time. (What do they cost to replace?)

Slow the feed down and the carbide tips will run no risk of damage. I'd skip the local brake and muffler shops and check out a shop that services racers. As some local roundy-round boys where they'd go to get rotors turned.

The shop had not issues with them but I have noticed a "whirring" kind of frequency now when I apply the brakes Most likely the carbide bit went bad during the cut. Or the feed was too fast. If I decide to cut rotors with holes in them (friends only) I will chamfer the holes before the cut, but If I have to cut the rotors with my own bits (meaning my own money) I would not likely do it. Bits do cost money and cutting rotors with holes does wear out the bit faster. Plus no guarantes on finnish quality.
