The Bosch 7 In. Premium Segmented Rim Diamond Blade provides upgraded and efficient cutting, thanks to Bosch's exclusive technology to optimize the cutting diamonds. Bosch embeds the highest quality diamonds in an enhanced 3-D pattern on the various dimensions of the blade to systematically ensure that the diamonds are more effectively engaged in cutting the concrete. This results in a better, faster cut. The blade's segment design reduces friction between segment and concrete, due to the regular segment length and spacing between segments. Each of the cutting segments on this blade is laser welded to the steel core, ensuring an extra strong and sturdy connection. It makes the blade durable and its cutting action stable. This is for use with a large angle grinder and can be used with some circular/worm drive saws.
