The MK Diamond MK-50 is a Supreme Grade segmented wet-cutting diamond blade made specifically for cutting block, carried here in the 24 inch size as part number 153165. MK describes it as a hard-matrix blade designed especially for cutting block, both precision and slump, providing good cutting speed and long blade life in abrasive materials. At 24 inches it is a masonry saw blade, bought by block and hardscape crews running a wet table saw or a large masonry saw.

Why a hard matrix
Block is abrasive, and an abrasive material wears the bond away faster than it wears the diamond. MK specifies a hard matrix on the MK-50 so the bond holds each diamond in place longer before releasing it, which is what produces the long blade life MK claims for this blade in block. The tradeoff is that a hard-bond blade is the wrong choice for hard, dense, non-abrasive material, where the bond will glaze instead of releasing fresh diamond.
Sizes
MK Diamond produces the MK-50 in 14 in, 18 in, 20 in and 24 in.
Operating speed
MK Diamond does not publish a per-blade RPM rating for this part. Its general speed guidelines for a 24 inch blade give 1,500 RPM as the recommended operating speed and 2,550 RPM as the never-exceed limit. Never run the blade above the saw manufacturer's stated maximum, and keep water on the blade throughout the cut.
Warranty
MK Diamond warrants its blades against manufacturing defects in normal service for one year from the date of purchase by the original consumer purchaser. On laser-welded blades, MK replaces the blade free of charge if the weld between segment and core fails in normal use; on brazed blades, if the brazed bond fails within the first .050 in of segment wear. Normal wear, misuse, abuse and unauthorized alteration are excluded, and MK does not pay freight.
Fits
MK Diamond does not publish a list of saws for the 24 inch MK-50. Confirm that your saw is rated for a 24 inch blade with a 1 inch arbor, and that its maximum spindle speed is within the guideline above, before ordering.

About the MK-50 block blade
The MK-50 is a Supreme Grade, hard-matrix segmented blade made for cutting concrete block, both precision and slump block. MK Diamond says the hard matrix provides good cutting speed and long blade life in abrasive materials, and the segments are laser welded to the core with a 10mm segment height.
Large-diameter blades like the 24-inch size are normally run on wet masonry saws and block saws. Match the arbor to your saw, keep water on the blade, never exceed the maximum RPM allowed by the blade or the saw, and wear eye, hearing and respiratory protection.
Why it works on the job
Matched to abrasive material. The hard matrix holds each diamond in place longer, which is how MK delivers long blade life in block.
Supreme Grade cutting speed. Laser-welded 10mm segments keep the blade cutting at a good pace on production work.
Right size for big saws. The 24-inch diameter and 1-inch arbor suit large masonry and block saws.
