The MK Diamond MK-62M is a segmented wet-cutting diamond blade engineered for hard stone, with the M designating the marble bond. Segmented hard-stone blades are chosen for cutting speed and an aggressive cut, which is what stone fabricators and tile contractors want when they are sizing slab and tile rather than polishing an edge. This is the 10-inch Premium grade blade on a 5/8-inch arbor, the common size for bench-top and portable wet tile saws.

- Tile setters running a 10-inch portable wet saw on a stone job
- Travertine, limestone and other softer natural stone where an aggressive cut helps

Matching the bond to the stone
MK specifies the 62 series for hard stone and splits it by bond. The M is the marble version; the companion MK-62G is bonded for granite. That distinction is not marketing. A bond built for dense granite runs too hard in marble and stops cutting cleanly, while a marble bond worked against granite gives up its diamonds far too quickly. If your shop cuts both, two blades will outlast one blade used for everything.
A segmented rim cuts faster than a continuous rim because the gaps clear slurry and let water reach the diamond, at the cost of a slightly rougher edge. For sizing cuts that will be finished or hidden, that trade is worth taking. Where a polished, chip-free arris is the finished product, a continuous rim blade is the better tool.
Frequently asked questions
What is the difference between the MK-62M and the MK-62G?
The bond. The M is bonded for marble and comparable hard stone; the G is bonded for granite. Using either one on the wrong stone costs you cutting speed or blade life, so shops that cut both usually keep one of each.
Does part number 137471 fit a standard 10-inch wet tile saw?
It is a 10-inch blade on a 5/8-inch arbor, which is the common arrangement on bench-top and portable wet tile saws. Check your saw arbor before ordering, since some larger machines use a 1-inch arbor and take a different part number in this series.
Can the MK-62M be run dry?
No. It is a wet-cutting blade. Water cools the core, clears the kerf and controls the silica dust that cutting stone produces. Running it dry will overheat the core and ruin the blade.
Will a segmented blade chip the face of the tile?
A segmented rim cuts faster and rougher than a continuous rim, so on a polished visible edge it can leave more to clean up. Cutting face-up with steady feed and plenty of water helps. For finished exposed edges a continuous rim blade is the better choice.
How long should the blade last?
Segment height is 8mm when new, and the usable life is what is left above the core. Life depends heavily on the stone, water volume and feed rate, so track it against your own work rather than a published figure.
