Need one dependable blade for everyday cuts in block, brick and concrete? The MK Diamond MK-299D 7-inch Standard Grade Blade (178mm, part 156417) is built for contractors, masons and maintenance crews who want a general purpose diamond blade for a 7-inch angle grinder or cut-off saw without paying for a specialty product. It is a standard grade blade from MK Diamond, a US diamond tool maker known for masonry and concrete blades.
Built for
- Cutting concrete block, brick and pavers on residential and light commercial jobs.
- General concrete and masonry cutting where a standard grade blade is the right balance of cost and performance.
- Contractors who keep one general purpose blade on the truck for mixed materials.
- Maintenance and facility crews doing occasional masonry repairs.
Why this blade
The MK-299D is described by MK Diamond as a general purpose blade for concrete and masonry materials. The segments are laser welded to the steel core and stand 10mm high, which gives you usable cutting depth in the segment before the blade is worn down. Because it is a standard grade blade, it is a practical choice when you need dependable performance across several materials rather than the highest diamond content for one specialty cut.
Use cases
Typical jobs include trimming block to fit, cutting brick for repairs and patch work, scoring pavers and making straight cuts in cured concrete. Match the blade diameter and arbor to your tool, wear eye and respiratory protection, and let the blade do the cutting rather than forcing it. MK Diamond lists this blade with its dry cutting general purpose blades, so it is suited to the quick, portable cuts made with a hand-held grinder or saw.

Selection and care tips
Before ordering, check the diameter, arbor or thread and the material you will be cutting, and keep a spare on hand for jobs that cannot stop. Inspect the blade or bit for cracks, missing segments or damage before every use, store it dry and flat, and replace it once the segments are worn down. Concrete and masonry dust can contain silica, so use water or dust collection and approved respiratory protection.
