Product Description
Milwaukee 8 in. 42-Tooth Dry Cut Cermet-Tipped Saw Blade
Model Number: 48-40-4515
The Milwaukee 48-40-4515 is an 8 in. 42-tooth Dry Cut Cermet-Tipped Saw Blade for cutting ferrous metals, stainless steel, mild steel, and a variety of metal profiles with Milwaukee and compatible 8 in. dry-cut chop saws and miter saws without sparks, heat buildup, or abrasive wheel consumption. Cermet is a composite material combining ceramic and metallic components — the cermet tip specification provides exceptional hardness and wear resistance in metal cutting applications, maintaining cutting edge sharpness through significantly more cuts than carbide-tipped blades in some ferrous metal cutting conditions, and performing particularly well on stainless steel and hardened steel where cermet's material properties provide advantages over conventional carbide in terms of cut quality and tip life. Dry-cut metal saw blades cut metal by shearing material along defined cut lines rather than grinding it away as abrasive cutoff wheels do, producing cut ends that require minimal deburring, generating chips rather than sparks, and maintaining workpiece temperature near ambient rather than generating the heat that can affect workpiece metallurgy.
The 42-tooth count is the standard specification for the 8 in. blade diameter in ferrous metal cutting — providing the tooth density needed for clean, accurate cuts in steel and stainless steel profiles including tube, angle, channel, flat bar, and solid rod at the range of material thicknesses the 8 in. blade is used for. Milwaukee manufactures dry-cut blades to professional quality standards with cermet tips precision-brazed to the blade's alloy steel plate body at the correct tip geometry for efficient metal shearing across the blade's rated cutting range. This blade is not designed for cutting aluminum, non-ferrous metals, wood, or masonry — the cermet tip specification is matched to ferrous and stainless steel cutting applications.
See Milwaukee's dry-cut and specialty saw blade lineup for all available diameters, tooth counts, and tip material specifications for ferrous, non-ferrous, and specialty metal cutting applications.
