The MK Diamond MK-62G is an 8-inch wet-cutting segmented rim diamond blade from MK Premium grade stone blade line, formulated specifically for granite. Granite is dense and abrasive, and a bond matched to it holds its edge longer and cuts more predictably than a general purpose stone blade. The thin 0.080 inch kerf removes less material per pass, which matters when you are working expensive slab.

Fits
No source reviewed lists specific saw models for the 8-inch MK-62G. Verify your saw accepts an 8-inch blade on a 5/8 inch arbor and is set up for wet cutting. Confirm fitment against your saw model number before ordering.

Use cases
- Granite countertop fabrication. Sizing and trimming slab where a thin kerf saves material.
- Granite and limestone tile. MK rates the MK-62G best on granite tile and limestone tile.
- Slate, blue stone and hard quartz tile. Rated better rather than best, but within the blade's range.
- Stone sill, tread and hearth work. Cutting dimensional stone to length on a wet saw.
- Shop and jobsite wet saw work. Any wet-fed saw taking an 8-inch blade on a 5/8-inch arbor.
Getting a clean cut
Stone work rewards patience more than pressure. Let the blade set its own feed rate rather than leaning into the cut, keep water moving through the kerf so the slurry clears and the rim stays cool, and set blade depth just past the thickness of the material instead of running at full depth. A new blade also benefits from a few break-in cuts in offcuts before the first finish cut, which opens the rim and brings the diamond to the surface.
Frequently asked questions
Can the MK-62G be run dry?
No. It is a wet-cutting blade. Running a wet blade dry overheats the core, glazes the diamond and can warp the blade. Confirm water is reaching the blade before the cut starts.
Is it suitable for marble?
MK does not recommend the MK-62G for marble tile. It rates granite and limestone tile best, and slate, blue stone and hard quartz tile better. For marble, use a blade bonded for it.
Why does granite need its own blade?
Granite is hard and abrasive. A bond matched to it wears back at the right rate to keep exposing fresh diamond, so it holds its edge longer and cuts more predictably than a general purpose stone blade.
Why does the thin kerf matter?
A 0.080 inch kerf removes less material per pass than a standard blade. On slab that is priced by the square foot, less waste per cut adds up across a job.
How do I stop the edge chipping?
Slow the feed and let the blade cut rather than pushing it, keep water flowing through the kerf, and set blade depth just past the material thickness rather than running at full depth. A new blade also benefits from a few break-in cuts in offcuts.
