Masons and bricklayers running high-speed cutoff saws need a blade that keeps up with production cutting without shredding segments or slowing the crew down. The MK Diamond MK-404D 8" Supreme Grade blade is built for exactly that: fast, clean cuts through brick, block, and masonry on high-speed gas and electric cutoff saws, whether you're trimming courses on a wall, cutting hardscape units to fit, or knocking out repair and punch-list work on site.
Use Cases
- Cutting brick and CMU block to length and angle on high-speed gas or electric cutoff saws during wall and veneer construction
- Trimming hardscape units (pavers, wall block, natural stone) to fit on patio and retaining wall installs
- Fast dry-cutting for demo, punch-list, and repair work where setting up a wet saw isn't practical
- General-purpose production cutting on concrete and masonry where crews need to keep moving between cuts
