First post figured I’d try to add some insight. The Freud’s coatings aren’t paint, they’re aluminum based and drastically reduce the amount of heat created, which can destroy a blade via warping or dull it more quickly by overheating the carbide. This is more important in ripping. The coating also reduces pitch/gum build up, which as we all know is annoying and messy. When I first used the Diablo blades with this coating, I was amazed at how smoothly the blade went through the wood, with very little effort required on my part. Then again, I was used to run of the mill throwaway construction blades from DeWalt, Black & Decker, Makita, etc., so it could of course have been the general lack of quality of what I was used to.
It seems other brands are now coating some of their blades with what appears to be the same thing.
There’s obviously some differences among the coatings. Freud uses an aluminum alloy, CMT uses Teflon, Irwin’s coating is just a thin layer of silicone, and the other brands are anyone’s guess. I’m not sure which brand first started applying these coatings, but Diablos were the first I saw them on. Regardless, I’m thankful they’re becoming more prominent, and I hope all blade manufacturers begin using them on all their blades.
