The MK Diamond MK-925D 4-1/2-inch Supreme Grade General Purpose Blade is a continuous rim diamond blade for dry cutting masonry. It suits masons, remodelers, paver installers, and maintenance crews who need a clean, dependable cut in brick and block with any tool that takes a 4-1/2-inch blade. The 10mm rim height gives you a solid working depth of diamond, so the blade keeps cutting through a full day of trim work instead of wearing out early.
Use cases
- Cutting brick, block, and pavers on remodeling and repair jobs
- Trimming masonry where a full-size saw will not fit
- Cutting notches and openings for pipes, conduit, and anchors
- Keeping one dependable general purpose masonry blade on the truck for facility and maintenance crews
Choosing the right one
Pick the blade diameter that matches your tool first, then confirm the arbor. This 4-1/2-inch MK-925D uses a 20mm-5/8 inch arbor and a .080 inch blade width, which keeps the kerf narrow and the cut controlled. If you cut mostly hard brick with a larger saw, MK Diamond also offers dedicated brick blades in its MK-414D family, and our team can help you compare.
Tips for best results
- Check that the blade diameter, arbor, and maximum RPM rating match your saw before you mount it, and never run a blade above its rated speed.
- Let the diamonds do the work. Steady, moderate pressure gives a straighter cut and longer blade life than forcing the blade through the material.
- Inspect the blade before each use for cracks, missing segments, or a warped core, and replace it if you see damage.
- Cutting masonry, concrete, and asphalt creates fine dust that can contain silica. Wear eye protection and a suitable respirator, and use dust control methods that fit your job site.
- Store blades flat or hanging in a dry place so the core stays true and the segments stay protected.
