The MK-404D 4-1/2-inch is a general purpose Supreme Grade diamond blade for concrete and masonry, sized for the angle grinder most contractors already own. The thin .080 inch width keeps cuts quick and the cutting effort low, and the laser-welded construction is MK Diamond's standard for a segment that stays attached. If you need one blade for brick, block, pavers and concrete repairs, this is the size to stock.
Use Cases

- Concrete cuts. Light concrete cutting, scoring and notching with a 4-1/2 in grinder.
- General job-site use. A single general purpose blade for mixed masonry work.
