The Diablo DMATP0450 4-1/2 Inch Diamond Tuck Point Blade for Masonry is a diamond tuck point blade made for mortar joint removal in masonry work. This is a tuck point blade designed for fast mortar removal with an angle grinder. Model Number: DMATP0450. If you are doing brick repair, repointing, or concrete and mortar cleanup, this blade is built to remove material quickly without stepping up to a larger grinder setup.

The big selling point here is Diablo's integrated dual blade design. Instead of acting like a basic cut-off wheel, this setup is meant to open up mortar joints at high speed so you can clean out old material efficiently. For masons and remodelers, that means faster joint prep before repointing and less time making repeated passes to get the width you need.

Diablo also backs the blade up with a hardened disc body that helps absorb vibration and increase impact resistance. That matters when you are working on older masonry, inconsistent joints, or tougher hardened material where a lighter-duty accessory can chatter, wear unevenly, or slow you down. A steadier blade helps you stay more controlled when following the joint line.

The diamond rim and optimized diamond segment distribution are there for a reason. Diablo calls out constant diamond exposure for maximum performance in high-speed cutting applications, which is the kind of detail pros care about because it affects how consistently the blade keeps cutting instead of glazing over and forcing extra pressure. In plain terms, it is built to stay productive when you are doing repeated mortar removal passes.

Fitment is straightforward for common grinder setups. The blade is designed for angle grinders and supports 7/8 inch, 20 mm, and 5/8 inch arbor sizes. Diablo also includes 20 mm and 5/8 inch bushings, which gives you more flexibility when matching the blade to the grinder you already own. That is useful on mixed crews or in shops where more than one grinder platform is in use.

At 4-1/2 inches in diameter with a maximum speed rating of 13,280 RPM, this masonry blade is sized for compact grinder work where control and access matter. It is intended for concrete and mortar applications, especially mortar joints in masonry. If your work is mostly repointing brick, touching up masonry repairs, or removing old joint material before fresh mortar goes in, this is the right kind of accessory. If you need a blade for general-purpose cutting across a wider range of materials, this is more specialized than that, and that is exactly why it works well for the job it was made to do.
