The MK Diamond MK-485D 20-inch Supreme Grade blade is a laser welded segmented blade for cutting asphalt and green concrete. It is built for paving, utility, and concrete contractors who saw joints and trenches in fresh or existing pavement and want longer blade life on abrasive material. A tall 12mm rim height gives extra usable diamond, and the laser welded segments hold up to the heat and stress of dry cutting.
Use cases
- Cutting asphalt and asphalt-over-concrete for patching and pavement repair
- Sawing control joints in green, freshly poured concrete
- Opening trenches for utility, drainage, and irrigation lines through paved surfaces
- Road, parking lot, and driveway crews that want a Supreme Grade blade with a deeper rim
Choosing the right one
Match the diameter to your saw and its maximum cutting depth, then confirm the arbor size and rated RPM before you order. The MK-485D is MK Diamond Supreme Grade line for asphalt and green concrete. If your work is mostly asphalt and you want a lower-cost contractor option, look at the MK-465D Premium Grade. Our team can help compare the two for your saw and job.
Tips for best results
- Check that the blade diameter, arbor, and maximum RPM rating match your saw before you mount it, and never run a blade above its rated speed.
- Let the diamonds do the work. Steady, moderate pressure gives a straighter cut and longer blade life than forcing the blade through the material.
- Inspect the blade before each use for cracks, missing segments, or a warped core, and replace it if you see damage.
- Cutting masonry, concrete, and asphalt creates fine dust that can contain silica. Wear eye protection and a suitable respirator, and use dust control methods that fit your job site.
- Store blades flat or hanging in a dry place so the core stays true and the segments stay protected.

The diamond segments are laser welded to the steel core. This bond is designed to stand up to the heat of dry cutting and to keep segments from coming loose.
Can I use it wet or dry?
MK Diamond lists this style of segmented blade for dry cutting. Follow the saw and blade guidelines, and use water where dust control is required on your job.
