The MK-525 is MK Diamond's Supreme Grade laser-welded blade for cured concrete, and this is the 14-inch size, part number 151713. Concrete cutting contractors use it for slab, curb, footing and wall cuts on saws in the 12 to 25 horsepower range.

Frequently asked questions
What is the MK-525 designed to cut?
MK lists it as a Supreme Grade laser-welded blade for cured concrete.
What horsepower saw does it need?
The MK-525 line is listed for 12 to 25 horsepower.
What does the 15mm segment height give me?
Taller segments carry more diamond-bearing material, which means more usable life before the blade wears down.
Do I need to cut wet?
Follow the operating notes on the blade and your saw. Cutting wet, where the saw allows it, reduces heat and dust.
How do I control silica dust when cutting concrete or masonry?
Cutting concrete and masonry releases respirable crystalline silica. NIOSH recommends water suppression or a shrouded tool connected to a HEPA vacuum, plus respiratory protection. Plan your dust control before the blade goes on the saw.
