The MK Diamond MK-304CR 4-inch blade (part 156090Y) is a premium grade, thin-rim blade for dry cutting hard and vitreous ceramic tile. MK Diamond designed the MK-304CR to ensure chip-free cutting of tile and other hard materials with minimal heat build-up, which matters when the face of the tile is the finished surface.
This 4-inch (102 mm) size has a .060-inch rim width, a 7mm rim height and a 7/8-inch-5/8-inch arbor, so it suits tile setters who want a small blade for notches, trims and detail cuts.
Use cases

- Tile installation. Handle trims, notches and small cuts on the job without a water feed.

Fit and compatibility
Choose by arbor: part 156090 has a 20mm-5/8-inch arbor and part 156090Y has a 7/8-inch-5/8-inch arbor. Confirm that your tool takes a 4-inch blade and matches the arbor before ordering, and check the tool maker's maximum blade speed.
Getting the most from the blade
Let the thin rim do the cutting instead of forcing it, keep the guard in place, and support the tile so it does not flex at the cut. Wear eye, hearing and respiratory protection, since dry cutting tile creates fine dust.
