Bosch 12-inch and 14-inch premium segmented rim diamond blades deliver fast, efficient cutting in concrete and other hard materials thanks to a tensioned blade core and a high-quality diamond formulation. The tensioned steel core is engineered with an innovative process that ensures each blade delivers smooth cuts with low vibration to reduce blade wobble. These general purpose segmented-rim blades offer a Bosch-exclusive diamond formulation that cuts most masonry and concrete materials. The 10 mm-segment height provides up to three times the life versus standard diamond blades. Each segment is laser-welded to the steel core. This is a premium connection method that offers the blade high mechanical strength and rigidity, ensuring greater stability during the cut. Bosch 12-inch and 14-inch reduction rings are 1 inch to 20 mm, which allows the blade to be used on application-specific concrete-cutting saws. The drive pin ensures the blade can be used on a walk-behind saw. These blades provide long life and smooth, fast cuts in concrete and masonry.
