The MK Diamond MK-404D 16-inch Supreme Grade high speed blade is a general purpose, laser welded blade for concrete and masonry materials. With a 20mm arbor and a .125 inch blade width, it fits saws that take a 16-inch blade and is made for contractors who want one dependable blade for mixed concrete and masonry cutting. Ten millimeter segments give a generous working depth of diamond.
Use cases
- Cutting concrete and masonry on remodeling, repair, and renovation jobs
- Sawing block, brick, and pavers for hardscape and site work
- General purpose cutting on mixed materials when changing blades costs time
- Rental yards and contractors who stock a versatile 16-inch blade
Choosing the right one
The MK-404D comes in more than one arbor for the same 16-inch size, so match the arbor to your saw. Part number 151847Z has the 20mm arbor. Its sibling part 151847 is the same blade with the 1 inch arbor. For asphalt or green concrete, choose an MK-465D or MK-485D instead. Our team can confirm the right fit.
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.
