Granite punishes a blade that was never meant for it. The MK Diamond MK-62G is built for stone shops and countertop fabricators who cut granite all day and need an edge that stays clean from the first slab to the last. This is the 7-inch size, part number 150392, running a thin .080-inch kerf on a 7/8-inch to 5/8-inch arbor. The segmented rim is cut to shed heat while it works, and MK builds the family on an 8mm rim height so there is real depth to wear through before the blade is finished. It is a wet-use blade, which is the whole point on granite: water carries the heat and the slurry away and keeps the stone from scorching at the cut line.
Built for
- Cut granite slabs and remnants on a wet tile or stone saw
- Trim countertop blanks to length before edge work
- Open sink and cooktop cutouts in granite tops
- Handle small-format granite tile and thresholds
- Serve fabrication shops needing a 5/8-inch or 7/8-inch arbor fit
Use cases
The first job is countertop fabrication. A 7-inch blade is the size shops reach for when the cut is short and control matters more than reach - squaring a blank, taking a slab down to a rough dimension, or working a cutout where a larger wheel simply will not fit the radius. The .080-inch kerf takes a narrow bite, so you remove less material and put less load on the saw, which shows up as a straighter line and less chipping along the top edge of the stone.
The second is repair and remnant work. Shops constantly recut offcuts into splashes, shelves and small vanity tops, and that work is hard on blades because every piece is a fresh entry cut. A segmented rim helps here - the gaps between segments let water into the cut and let heat and slurry back out, so the blade is not fighting its own friction on repeated short passes.
Because this is a wet-only blade, the practical requirement is a saw that delivers water to the blade continuously. Running it dry is the fastest way to cook the diamond matrix and glaze the segments. Match the arbor before ordering: this part is bushed for a 7/8-inch or 5/8-inch spindle, which covers most shop wet saws and stone-cutting circular saws.

Frequently asked questions
Can the MK-62G be run dry?
No. MK Diamond specifies the MK-62G for wet use only. It needs a continuous water feed to carry heat and slurry out of the cut; running it dry will glaze the segments and shorten blade life.
What materials is this blade meant for?
Granite and similar hard stone. It is a stone blade, not a general-purpose concrete or masonry blade, and it is not intended for asphalt or green concrete.
What arbor does part 150392 take?
A 7/8-inch to 5/8-inch arbor, so it fits shop wet saws and stone-cutting circular saws with either spindle size.
Why does a segmented rim matter on granite?
The gaps between segments let water reach the cutting edge and let heat and slurry escape. On a dense material like granite that cooling path is what keeps the blade from overheating during repeated cuts.
How thick is the cut this blade makes?
The blade is .080 inches wide, a thin kerf that removes less stone and reduces load on the saw compared with a heavier blade.
