MIBRO's 12 in. 80 Tooth Circular Miter Saw Blade provides cleaner cuts and cutting efficiencies to improve your productivity. An ATB tooth pattern and thin kerf design minimize tearout in the cut material and provide a smoother finish. All teeth are C2 micrograin carbide that are welded and sharpened using precision computer-controlled equipment. C2 micrograin carbide teeth provide the perfect balance between performance and affordability. Heat expansion slots dissipate heat and allow blade to run cooler, increasing its service life. In combination with the anti-kickback feature, this minimizes wobble and warp to ensure safe and smooth operation.
