Where the 799D sits in the range

MK Diamond describes the MK-799D as a general purpose, high speed blade for concrete and masonry materials. It is the premium grade in MK's high speed lineup, positioned below the supreme grade MK-404D on diamond concentration and above the economy grades. For contractors making a lot of routine cuts in concrete, block and brick, the premium grade is the usual value choice; the supreme grade earns its price on high-volume or abrasive work.

Fits

MK specifies this blade by diameter, width and arbor rather than by saw model. A 20-inch blade requires a saw rated for that diameter, and the 1-inch arbor must match your spindle. Confirm both your saw's maximum blade capacity and its maximum rated blade speed against the machine's plate before ordering; a blade larger than the saw's rating is a safety problem, not just a fit problem.
