The MK-7503 is MK Diamond's Professional Grade diamond blade for cured concrete with soft aggregate and abrasive sand, made for concrete cutting crews working in abrasive, sandy mixes. Part number 154094 is the 18-inch (457mm) size with a .155-inch blade width and a 1-inch arbor, so it mounts on the high horsepower flat saws that professional cutting crews already run. It carries 13mm segments for a working life that suits daily production cutting.

Fit and compatibility
Confirm that your flat saw takes a 18-inch blade, that the shaft accepts a 1-inch arbor, and that the .155-inch blade width suits your blade guard and cut depth. MK Diamond designs the MK-Pro Series for high horsepower flat saws, and additional diameters, widths and special arbors are available on request. Check the saw maker's rated speed against the blade before mounting.
Why choose this blade
Flat saw crews buy blades by the job, not by the box, so the right bond and segment matter more than the sticker price. The MK-7503 is part of MK Diamond's MK-Pro Series, which the manufacturer designs and engineers for high horsepower flat saws. Matching the blade to the material, here cured concrete with soft aggregate and abrasive sand, keeps cutting speed up and keeps the saw from glazing the segments or wearing them out early. Because MK Diamond also offers other diameters, widths and special arbors on request, you can stay with one blade family as your jobs change.
Choosing the right size
Pick the diameter that gives the cut depth you need with the guard and saw you have, then match the blade width to the kerf your job requires. A .155-inch width is the width listed for this 18-inch size, so check it against your cutting specification and guard clearance before you order. If you are replacing a worn blade, compare the diameter, width and arbor with the one coming off the saw.
Getting the most from the blade
Run the blade with a steady water supply as MK Diamond directs, keep the blade guard in place, and let the segments do the cutting instead of forcing the saw through the material. Even feed pressure and a straight line keep the cut clean and help the blade wear evenly. Wear eye, hearing and respiratory protection and follow the saw maker and MK Diamond safety guidance.
