DLC Coated Lifters

DLC coatings are slippery as kitty **** on a linoleum floor. The cost has become very affordable. You need to find a milling cutter regrinder that will coat them as they have a coating service for the endmills and other tools they sharpen. They suck way,way,way less horsepower on a machine tool and cut way better at increased speeds and feeds and stay sharp an incredible long time. I can see why they are using this coating on lifters and other engine components. I have been using these coated cutting tools for at least 15 years. This will give you an edge over your competition.
