Tenryu MP-25580CB 10" 80t miter pro blade ATAFR (Alternative Top Alternate Face w/ Raker) Extra sharp cutting tips reduce load on saw. Face beveling diverts cutting load left and right instead of straight on. Creates a better shearing action - especially in cross-grain, natural wood. Fully-hardened, expertly-tensioned tool steel bodies for true and accurate cuts. High-grade, fine grain carbide tips for long life. Super-fine grit honing of carbide edge for clean, smooth cuts. Additional resin bond-filled expansion slots for even quieter cutting.
