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 Circular Saw Blade engineered for professional metal cutting on the Milwaukee 6370-20 Dry Cut Saw and compatible 8 in. dry-cut chop saws, miter saws, and metal cutting circular saws. The blade cuts a wide range of ferrous and non-ferrous materials 3/32 in. and thicker, including mild steel, stainless steel, aluminum, pipe, angle iron, bar stock, conduit, steel studs, and structural or shape steel profiles. Where abrasive cutoff wheels grind material away in a shower of sparks, generate significant workpiece heat, and are consumed rapidly as the wheel wears down, the 48-40-4515 shears metal along defined cut lines using precision-brazed cermet-tipped teeth, producing chips instead of sparks, keeping the workpiece cool enough to touch immediately after the cut, and delivering burr-free cut ends that require minimal deburring before the next fabrication step. Milwaukee engineers the cermet tips with cobalt-infused tungsten carbide construction, brazed to a hand-tensioned hardened alloy steel body, delivering both the tip life and blade stability that professional metal cutting contractors demand.
The 42-tooth count is Milwaukee's specification for the 8 in. blade diameter, providing the tooth density needed for clean, accurate cuts across the blade's rated material range. Teeth are configured in an Alternate Top Bevel plus Raker (ATB+R) grind pattern, which combines the shearing action of alternating top bevel teeth (excellent for crosscutting metal profiles cleanly) with periodic raker teeth (which clear chips efficiently and reduce cutting force), giving the blade balanced performance in tube, angle, channel, flat bar, and solid rod applications. The 0.0 degree hook angle keeps the tooth entry aggression neutral, which is the correct choice for metal cutting where too much positive hook angle causes tooth grabbing and blade catch. Laser-cut vibration dampening slots in the steel body significantly reduce blade vibration during the cut, which delivers three simultaneous benefits: reduced heat generation at the cutting surface (keeping workpiece metallurgy unaffected), reduced cutting noise and operator ear fatigue, and reduced spark generation for a cleaner, safer working environment.
The 48-40-4515 is designed to run at a maximum 5,000 RPM with a 5/8 in. arbor hole that fits standard 8 in. metal cutting chop saw spindles, and delivers up to 2-3/4 in. of cutting depth. The 0.073 in. plate thickness and matching 0.073 in. kerf balance rigidity for straight cutting against material removal rate for efficient cutting. Milwaukee designed the blade specifically to pair with the Milwaukee 6370-20 Dry Cut Saw, which is the corded 8 in. metal cutting circular saw platform in Milwaukee's dry-cut lineup, though the blade is also compatible with third-party 8 in. dry-cut chop saws, miter saws, and metal cutting circular saws that meet the 5/8 in. arbor and 5,000 RPM maximum speed specifications. The blade is optimized for dry cutting without water or coolant. See Milwaukee's complete dry-cut and specialty metal cutting blade lineup for additional diameter, tooth count, and tip material configurations across ferrous, non-ferrous, and specialty metal cutting applications.
