Diablo Concrete Demon Diamond Segmented Turbo Tuckpoint Blade
The Concrete Demon tuckpoint blade stacks two diamond blades on one arbor, separated by a precision washer, so a single pass removes a 6.1 mm wide strip of mortar. SPEED-Edge slots reduce vibration for up to 30% faster cuts than standard segmented diamond discs, and the laser-welded segments are rated for up to 2X longer life, by Diablo's figures.
Two sizes for angle grinders, 4-1/2 in. and 5 in. Both fit 7/8 in., 20 mm and 5/8 in. arbors and include 20 mm and 5/8 in. bushings. Diablo lists them for concrete, mortar, grout, brick and block.
Dry cutting only. Diablo does not rate the tuckpoint blade for wet use.
