Diablo DMATP0500 5-Inch Dual-Blade Diamond Tuck Point Wheel
The Diablo DMATP0500 5-Inch Dual-Blade Diamond Tuck Point Wheel is an industrial mortar joint removal disc engineered to rake out deteriorated mortar between brick, block, and stone surfaces. Rated for dry cutting operations at rotational speeds up to 12,200 RPM with a 0.240-inch (6.1mm) kerf on a 7/8-inch arbor (includes 20mm and 5/8-inch bushings), this 5-inch hardened steel wheel utilizes a dual-blade sandwiched matrix with industrial diamond grit. Delivering accelerated joint clearance compared to single-blade grinding wheels, this masonry tuckpointing disc solves slow joint raking, core chatter, and blade binding challenges across historic building restoration and brick repointing jobs.
Best Used For:
- Brick & Block Mortar Joint Raking: Removing soft or weathered lime and Portland mortar joints prior to fresh tuckpointing and repointing.
- Concrete Slab Crack Chasing: Routing out irregular cracks in concrete floor slabs to create clean, uniform channels for epoxy sealant application.
- Stone & Masonry Restoration Prep: Clearing joint beds along stone facades, chimney stacks, and retaining walls without damaging adjacent brick edges.
Key Performance & Safety Features
- Dual-Blade Sandwiched Construction: Twin diamond rim profile clears wider mortar beds rapidly in a single pass without needing multiple grinding runs.
- 0.240-Inch (6.1mm) Heavy Kerf: Wide joint-cleaning width prepares standard mortar seams instantly for tuckpointing compound injection.
- 12,200 RPM Maximum Speed Rating: High-speed reinforced core safety-engineered for 5-inch small angle grinders and dedicated tuckpointing saws.
- Industrial-Grade Diamond Matrix: Formulated with concentrated synthetic diamond grit to maintain aggressive removal rates across dry abrasive masonry.
- Vibration-Dampening Hardened Steel Plate: Rigid steel core absorbs lateral impact and maintains true tracking inside deep wall joints.
- Multi-Arbor Mounting Versatility: Mates natively with 7/8-inch grinder spindles or adapts to 20mm and 5/8-inch arbors via included reduction bushings.
