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.
