Milwaukee Circular Diamond Saw Blade, 4" Blade, 7/8in 20mm 5/8in

4 in. Diamond Premium Turbo Saw Blade — a small-format premium diamond blade for 4 in. and 4-1/2 in. angle grinders for cutting concrete, masonry, brick, tile, and stone in the compact grinder format. The premium turbo segment profile combines continuous-rim smooth cutting characteristics with turbo face wave geometry — the turbo profile increases the diamond cutting contact area per revolution for faster cutting speed than a flat segment profile while the continuous-rim format provides cleaner cut edges with less chipping at the cut perimeter compared to segmented blades in brittle tile and fine masonry materials. The premium diamond specification uses higher-quality diamonds in an optimized bond that maintains consistent cutting speed across the full blade service life in hard commercial concrete and dense masonry where standard blades glaze progressively.

The 4 in. compact diameter enables cutting in the tightest access positions, along walls and in corners, and in the confined work spaces of renovation and maintenance work where the larger 4-1/2 in. blade contacts surrounding surfaces. The premium turbo blade is practical for demanding masonry cutting applications where cut quality, cutting speed, and blade life are all important — tile and stone cutting where chipping at cut edges is unacceptable, hard aggregate concrete where standard blades slow too quickly, and the production cutting tasks where the premium blade's consistent performance throughout its service life provides better operational economics than standard-grade blades. Wet cutting extends blade life and suppresses silica dust in demanding cutting applications.
