Tackling stone, tile, or marble work? These 100mm (4 inch) diamond saw blades are built for the job. They have a special multi-hole widened design that does two great things: it helps dissipate heat quickly (so the blade doesn't overheat and warp), and it makes the blade more stable and durable during cutting. The diamond segments are brazed on (not just welded), which means they're really secure and won't fall off. The 1.0mm thin base makes them super flexible for smooth grinding and chamfering edges. They fit most standard 4\ angle grinders with a 20mm arbor hole. Perfect for pros or serious DIYers working with tiles, ceramic, marble slabs, or natural stone. Use them for cutting, shaping, or creating clean beveled edges. A set of 3 means you always have a sharp one ready.
