Product Description
Milwaukee 16 in. Asphalt and Green Concrete Segmented Diamond Blade
Model Number: 49-93-7245
The Milwaukee 49-93-7245 16 in. Asphalt and Green Concrete Segmented Diamond Blade is a professional-grade diamond cutting blade engineered for full-depth cuts in asphalt, green concrete, and cured concrete on roadwork, utility cuts, sidewalk and driveway replacement, parking lot maintenance, expansion joint cutting, and any masonry application where the operator needs aggressive cutting speed combined with the longevity to make it through a high-production cutting day. The 16 in. blade size matches the cutting capacity of cut-off saws, brick saws, walk-behind masonry saws, and self-propelled masonry saws used across the construction and concrete trades, fitting directly onto the spindle of any saw that accepts a 16 in. blade with a 1 in. or 20 mm arbor.
The defining engineering feature on this blade is the laser-welded drop segment design. Conventional diamond blades wear from the side as well as the top during cuts in abrasive materials, and once the segments wear narrower than the steel core, the blade begins binding in its own kerf, slowing the cut and burning out the diamond matrix. The drop segments on the 49-93-7245 sit slightly proud of the core on both sides, sacrificing themselves first and protecting the core from undercut wear, which is the primary failure mode for diamond blades cutting asphalt and green concrete. The result is up to 3 times the cutting life of a comparable conventional diamond blade in concrete applications, while still delivering full cutting depth across the blade's service life. Wide gullets between the segments quickly evacuate slurry, abrasive dust, and material debris from the cut, which keeps fresh diamond exposed at the cutting edge and prevents the glazing and loading that slows down lesser blades.
The blade is rated for both wet and dry cutting, giving the operator the flexibility to use water-fed saws for cleaner cuts and reduced dust on green concrete applications, or to run dry on asphalt cuts where water introduction is undesirable. Maximum operating speed is 5,460 RPM, which covers the speed range of all common gas, electric, and cordless cut-off saws and walk-behind masonry saws. Always operate the blade within the saw manufacturer's specified RPM limits, use the correct guard configuration for the saw and application, and follow proper safety protocols for asphalt and concrete cutting including PPE for silica dust exposure. For best blade life, allow the blade to do the cutting without forcing the saw forward, dress the blade if it begins to glaze on hard cured concrete, and use water cooling when the application allows.
