The MK Diamond MK-404D 9" Supreme Grade High Speed Blade is a general-purpose blade for contractors cutting concrete and masonry materials on the same job site, rather than one blade dedicated to a single material.
Built for mixed concrete and masonry work
Not every job is pure brick, pure block, or pure concrete - remodeling, demolition, and general masonry crews often need one blade that performs across all of it. The MK-404D's laser-welded, 10mm segments are built for exactly that mixed-material, high-speed cutting. Typical uses include:
- General demolition and remodeling cuts through concrete and masonry
- Block, brick, and mixed masonry cutting on the same job
- Production cutting for masonry contractors who need one blade for multiple materials
- Field cut-off saw work where swapping blades between materials isn't practical

Frequently asked questions
What materials does the MK-404D cut?
Concrete and masonry materials generally - it is MK Diamond's general-purpose high speed blade line, not a blade built for one specific material like brick or asphalt.
Is the MK-404D wet or dry cutting?
It's built as a general-purpose masonry blade and is commonly run dry with cut-off saws and grinders in the field; check your saw's manufacturer guidance if you plan to add water for dust control on a given job.
What size saws fit the 9-inch MK-404D?
Standard 9 inch cut-off saws and masonry saws sized for a 9 inch blade with the blade's arbor.
How is this different from MK's brick-specific blades like the MK-414D?
The MK-404D is a general-purpose concrete and masonry blade, while lines like the MK-414D are built and marketed specifically for hard brick. If most of your cutting is one material, a material-specific blade can outperform a general-purpose one; the MK-404D is the better choice when your cutting mixes concrete, block, and masonry on the same job.
What does 'Supreme Grade' mean on this blade?
Supreme is MK Diamond's top grade designation within a blade family, generally meaning a longer-lasting segment bond and cutting life than the base grade in that same line.
