Sawsmith� 10-inch Carbide-Tipped Thin-Kerf Blades Slice Smoothly Through the Hardest Woods with Less Frequent Sharpening than Steel Blades. \n \nThin Kerfs Make the Difference \nSawsmith� carbide-tipped blades deliver a narrower 3/32" kerf, unlike many blades that cut a kerf of 1/8" or more. As a result, Shopsmith blades cut quickly and efficiently and require less horsepower than many competitive blades. \n \nExpansion Slots Reduce Noise and Vibration For a Cleaner Cut \nSawsmith� blades feature expansion slots to minimize vibration giving you a cleaner cut. They'll also reduce noise the blade produces.
