Description
Milwaukee 48-40-1048 10-1/4" 28T Thick Kerf Framing Circular Saw Blade
Conquer heavy timber cutting and demanding framing jobs with the Milwaukee 48-40-1048 10-1/4" 28T Thick Kerf Framing Circular Saw Blade. Purpose-built for 10-1/4" beam-cutting circular saws, this blade uses a high-performance 0.102" thick kerf steel body that eliminates blade wander, flexing, and wobble when cutting through dense construction materials.
Every tooth is tipped with durable cobalt-infused tungsten carbide to resist dulling and withstand abrasive materials such as treated lumber, wet studs, and engineered beams (LVL, PSL, LSL). Integrated diamond cooling vents speed up chip ejection and reduce thermal buildup to prevent gumming, warping, and binding under heavy loads.
Key Features:
- High-Performance Thick Kerf (0.102"): Built thick to resist deflection and provide unmatched blade stiffness for razor-straight rip cuts.
- Cobalt-Infused Carbide Teeth: Formulated to stay sharper significantly longer than standard framing teeth, even in treated or wet wood.
- Diamond Heat Vents: Specialized laser-cut venting pattern expels chips rapidly and keeps the blade running cool during high-friction continuous cuts.
- Universal 5/8" Diamond Knock-Out Arbor: Fits all standard 10-1/4" circular saws and worm drive / hypoid-style framing saws.
- Broad Engineered Lumber Compatibility: Cuts clean through structural LVL, PSL, OSB, subflooring, heavy timbers, and hardwoods without bogging down.

Frequently Asked Questions
Why choose a thick kerf blade over a thin kerf blade for framing?
A thick kerf blade (0.102") provides greater structural rigidity and resistance to heat deflection. While thin kerf blades cut faster with less power, thick kerf blades prevent blade flex, wobble, and wander when making deep, straight rip cuts through dense timbers, LVL headers, and treated wood.
What circular saws will this blade fit?
The Milwaukee 48-40-1048 is engineered for all 10-1/4" circular saws. It features a standard 5/8" round arbor with an integrated 13/16" diamond knock-out to accommodate standard sidewinder and worm drive / hypoid-style saws.
Can this blade cut wet or pressure-treated lumber?
Yes. The cobalt-infused carbide teeth and diamond-shaped cooling vents allow the blade to clear wet, pitchy saw dust and chips quickly, significantly reducing heat buildup and resin binding.
What engineered wood types is this blade suitable for?
It is optimized for demanding engineered lumber including Laminated Veneer Lumber (LVL), Parallel Strand Lumber (PSL), Oriented Strand Board (OSB), Laminated Strand Lumber (LSL), and heavy subflooring panels.
How does diamond venting improve cutting performance?
The laser-cut diamond venting pattern improves airflow across the blade body to dissipate friction heat, while dampening vibration to reduce operational noise and prolong tooth sharpness.
