Diablo Diamond Segmented Masonry Cut-Off Blade
Diablo's segmented blade cuts concrete, concrete with rebar, brick and cinder block. Taller diamond segments sit on an ultra-durable bond, which Diablo rates for up to 2X longer life than its standard diamond cut-off discs. The diamond layout keeps fresh diamond exposed at speed, and a hardened disc body absorbs vibration.
Four sizes. The 4 in., 4-1/2 in. and 5 in. blades fit 7/8 in., 20 mm and 5/8 in. arbors and include 20 mm and 5/8 in. bushings. The 7 in. fits DM 7/8 in. and 5/8 in. arbors and includes a 5/8 in. bushing. Diablo lists the smaller sizes for angle grinders and the 7 in. for angle grinders and circular saws. Every size cuts wet or dry.
Not the tile blade. Diablo rates its continuous rim disc for tile, porcelain and stone. Use this segmented blade for concrete, brick, block and pipe, and see the continuous rim disc for tile.
