Bosch Edge Circular Saw Blades for wet lumber start sharp, stay sharp and resist impact damage for long life. They are designed for tough construction jobs, because they are engineered with Brute Carbide, an upgraded C3/C4 micrograin carbide formulation that increases impact resistance. They have face-ground teeth for clean cuts and excellent finish. The SpeedCoat finish means less friction for fast effortless cuts without gum-up in wet lumber. To avoid warping, these blades have been built with expansion slots. These blades also feature control cut shoulders to reduce kickback, and they have body slots for excessive heat.
