Cut concrete, block and other masonry with one general purpose blade. The MK Diamond MK-404D 12-inch Supreme Grade High Speed Blade (part 153718) is made for contractors, masonry crews and rental yards that need a dependable blade for everyday cutting.
Built for
- General purpose cutting of concrete and masonry materials on job sites.
- Contractors and masons who want one blade that handles a mix of block, brick and concrete.
- Rental yards and facilities crews that stock a standard 12-inch blade.
Why this blade
MK Diamond sells the MK-404D as its general purpose, high speed segmented blade for concrete and masonry. The segments are laser welded to the steel core, and at 10mm the segment height gives you cutting life for regular use. The 12-inch diameter with a 1-inch arbor is a common configuration for walk-behind and handheld cut-off saws built for 12-inch blades.
Because it is a general purpose design rather than a specialty blade, it is a practical choice when your crew cuts different materials through the week and does not want to swap blades for every task. For very hard or very abrasive materials, MK Diamond offers other blade families, and our team can help you compare them.
Where it fits in your blade lineup
The MK-404D family covers a range of diameters, so crews that run several saws can standardize on one blade series and keep spares that match across machines. The 12-inch size is a frequent pick for walk-behind flat saws and large cut-off saws, while smaller diameters in the same family are used on handheld and tabletop equipment. If you are replacing a worn blade, compare the diameter, arbor and segment height printed on the old blade with the specifications below before you order.
Keep in mind that a diamond blade cuts best when it is run at the correct speed with steady, moderate pressure. Let the blade do the work, avoid twisting it in the cut, and replace it when the segments are worn down to the core.
