The CMT 250.024.08 Framing and Ripping Saw Blade is a professional-grade 8 to 8-1/4 in. circular saw blade engineered for demanding framing, decking, and ripping applications. Designed for use with corded and cordless circular saws, this 24-tooth blade cuts cleanly and efficiently through hardwood, softwood, OSB, pressure-treated lumber, and laminated beams. The Alternate Top Bevel tooth geometry and Tri-Metal Brazing construction deliver consistent performance on the jobsite, making it a reliable choice for contractors and tradespeople who need a blade that handles both structural wood and engineered lumber without compromise.

Key Features

• 24-Tooth ATB 15 deg. Grind - the Alternate Top Bevel geometry at 15 deg. sharpening angle produces clean, efficient cuts across hardwood, softwood, OSB, and laminated beams, reducing tear-out and splintering during framing and ripping operations.
• 20 deg. Hook Angle - an aggressive hook angle drives the blade through material with less resistance, improving feed rate and reducing operator fatigue during long ripping cuts.
• Tri-Metal Silver-Copper-Silver Brazing - the special silver-copper-silver Tri-Metal Brazing method bonds teeth to the plate with exceptional strength, allowing them to handle high stress and impact especially when cutting harder woods and composite materials, extending tooth retention and overall blade longevity.
• Precision Blade Body Flatness via Special Straightening Processes - blade body flatness is obtained via special straightening processes that guarantee exceptionally reduced tolerances, resulting in a stable, accurate cut with minimal deflection during use.
• Balancing Performed on All Saw Blades - balancing performed on all saw blades guarantees maximum stability, which translates to smoother operation, reduced vibration, and improved cut quality in both corded and cordless circular saw applications.
• Thin Kerf Design (0.082 in. kerf / 0.048 in. plate) - a thin kerf removes less material per pass, reducing waste and putting less strain on cordless tool batteries, making this blade well-suited for extended jobsite use.
• Knockout Pin Hole for 5/8 in. Bore Compatibility - the knockout arbor adapter allows the blade to fit a range of circular saws with different bore configurations, maximizing tool compatibility on the jobsite.
• HW (Tungsten Carbide) Tooth Material - carbide tips deliver superior hardness and edge retention compared to standard steel teeth, maintaining sharpness through extended cutting sessions in dense and engineered wood products.
• 9,000 Maximum RPM Rating - a high maximum RPM rating ensures safe, compatible operation with both corded circular saws and high-speed cordless models used in professional framing work.

Why This Product

• Built for framing and ripping in a single blade - the 24-tooth ATB configuration with a 20 deg. hook angle is optimized for both cross-grain framing cuts and long-grain ripping, eliminating the need to switch blades between tasks on the jobsite.
• Compatible with a wide range of circular saw platforms - the 8 to 8-1/4 in. dual-diameter design with a 5/8 in. knockout bore fits both corded circular saws and cordless circular saws, giving crews flexibility across different tools without buying separate blades.
• Engineered tooth attachment for impact-prone cutting - Tri-Metal Silver-Copper-Silver Brazing is specifically designed to handle the high stress and impact of cutting harder woods and composite materials like OSB, pressure-treated lumber, and laminated beams, reducing the risk of tooth loss mid-cut.
• Precision manufacturing reduces setup time and rework - blade body flatness obtained via special straightening processes and full balancing on every blade means it runs true right out of the package, minimizing the need for adjustment and producing repeatable, accurate cuts from the first pass.

Frequently Asked Questions

What machines is this blade compatible with?

This blade is designed for use with corded circular saws and cordless circular saws. The 8 to 8-1/4 in. dual-diameter sizing and 5/8 in. knockout bore make it compatible with a wide range of circular saw platforms used in professional framing applications.

What is Tri-Metal Brazing and why does it matter for jobsite use?

Tri-Metal Brazing refers to a special Silver-Copper-Silver layered brazing process used to bond the carbide teeth to the blade plate. This method allows the teeth to handle high stress and impact especially when cutting harder woods and composite materials, reducing the likelihood of tooth loss under demanding cutting conditions.

What is the difference between the kerf thickness and the plate thickness on this blade?

The kerf thickness is 0.082 in., which is the width of material removed by the cutting teeth during a pass. The plate thickness is 0.048 in., which is the thickness of the steel body of the blade itself. The difference between these two measurements creates blade clearance that prevents the plate from binding in the cut.

Why does blade balancing matter for circular saw performance?

Balancing performed on all saw blades guarantees maximum stability during operation. A properly balanced blade runs with reduced vibration, which improves cut quality, extends the life of both the blade and the saw, and makes the tool more comfortable to control - particularly important when using cordless circular saws for extended framing sessions.
