Asphalt and green concrete give a blade the same problem from two directions: both are soft and abrasive enough to strip a section built for hard cured aggregate. The MK Diamond MK-465D is the premium grade dry blade built for that pair, and this is the 14" size, part number 150618Z, at .125" wide on a 20mm arbor. Premium sits in the middle of MK Diamond's three blade grades, pairing contractor-grade cutting speed with the longer wear life crews want on production work. Being a dry blade is what makes it a practical site tool - no water tank, no slurry to manage, and it goes on the handheld or walk-behind saw the crew already has in the truck.
Built for
- Cut asphalt paving on parking lots, drives and roadways
- Saw control joints and openings in green concrete
- Open utility, trench and patch cuts without a water feed
- Run dry on handheld and walk-behind high speed saws
- Cover both asphalt and fresh concrete with one blade
Use cases
The first job is asphalt cutting where water is a nuisance. Utility cuts, patch perimeters and parking lot repairs often happen where there is no water supply, or where slurry running across a finished surface creates more cleanup than the cut itself. A dry blade removes that whole problem, and an asphalt-rated section is what keeps it from loading up in soft material.
The second is green concrete. Fresh slabs need their control joints cut before random cracking starts - the joint is a planned crack that steers shrinkage movement where you want it. The practical test is the same one concrete crews always use: run a short test cut and look at the edge, and cut as soon as the saw stops raveling. Too early tears aggregate out of the surface; too late and the slab has already cracked on its own.
If you are choosing between MK's two blades for this application, the difference is grade. MK lists the MK-465D as the premium grade blade for asphalt and green concrete and the MK-485D as the supreme grade blade for the same materials, with supreme carrying the higher diamond concentration. Premium is the sensible pick on mixed or intermittent work; step up to supreme for sustained production cutting on a higher-powered saw.

Frequently asked questions
Is the MK-465D wet or dry?
It is a dry cutting blade, so it runs on handheld and walk-behind high speed saws without a water feed.
What is the difference between the MK-465D and the MK-485D?
Grade. MK lists the MK-465D as the premium grade blade for asphalt and green concrete and the MK-485D as the supreme grade blade for the same materials. Supreme carries the higher diamond concentration and suits sustained production cutting on a higher-powered saw.
Can it cut both asphalt and fresh concrete?
Yes, that is the application MK specifies for this family - asphalt and green concrete. Both are soft, abrasive materials that need a different section from cured concrete.
When should green concrete be cut?
Cut as soon as the saw stops raveling the edge. Make a short test cut and inspect it: if the cut pulls aggregate out of the surface the slab needs more time, and waiting too long risks the slab cracking outside the joint.
What does a Z at the end of the part number mean?
It is the 20mm arbor version of the same blade. Diameter and width are unchanged, so order by the spindle on your saw.
