The MK-485D is MK Diamond's Supreme Grade dry-cutting blade for asphalt overlay and green concrete. Part number 152647 is the 18-inch size with a .375-inch core and a 1-inch arbor, so it mounts on an 18-inch saw with a standard 1-inch shaft. It is a laser-welded segmented blade with a 12mm segment height, built for contractors who cut fresh pavement and early-age slabs without a water supply on the saw.
Use cases
- Asphalt overlay and patching. Straight cuts through asphalt surfaces for utility trenches, patch repairs and edge trimming.
- Green concrete saw cutting. Joint cutting in new slabs soon after the pour, the work MK lists this blade family for.
- Dry-cut job sites. Work where running water is impractical, so you can set up the saw and start the cut.
- Replacing a worn blade. A like-for-like swap when a 18-inch .375-inch-core blade has reached the end of its segments.

Fit check
Confirm three things before you order: your saw takes a 18-inch blade, the shaft or flange accepts a 1-inch arbor, and the .375-inch core width suits your blade guard and cut depth. If you are unsure, check the blade size on your saw's data plate.
