The CMT Xtreme Demolition Saw Blade - 7-1/4" x 5/8" 24T is a high-performance circular saw blade built for the most demanding demolition and rough-cutting environments. Featuring a patented low mass plate design, an Alternate Top Bevel tooth grind, and CMT's trademarked Orange Shield coating, this 7-1/4 in. blade is engineered to deliver more cuts per charge on cordless saws while maintaining the durability needed to handle wood with embedded nails, pressure-treated lumber, OSB, laminated beams, and other demolition materials. Whether you are ripping through salvage lumber or making crosscuts in mixed debris, this blade is designed to keep cutting where other blades stop.

Key Features

• Low Mass Plate Design (Patented) - reduces blade mass and minimizes heat buildup, which translates directly into increased cutting efficiency on both cordless and corded circular saws, delivering more cuts per battery charge and less downtime on the job.
• Alternate Top Bevel (ATB) Tooth Grind at 5 deg. - the alternating bevel geometry distributes cutting forces evenly across each tooth, producing cleaner entry cuts through demolition materials and reducing blade deflection under load.
• Loose Nail Application Testing - CMT tested this blade in a loose nail application where nails are free to move slightly during cutting, a more demanding standard than the fully embedded nail tests used by many competitors, meaning real-world durability is built into the design from the start.
• Orange Shield Coating - CMT's exceptional trademarked protective coating guards the blade body against corrosion and wear, extending tool life under the harsh, repetitive conditions of demolition work.
• Thin Plate at 0.049 in. with 0.090 in. Kerf - the slim plate reduces material resistance during cutting while the kerf width maintains enough tooth mass for durability, resulting in efficient stock removal with less motor strain on your saw.
• Knockout Pin Hole (5/8 in. Bore) - the 15.88mm bore with a knockout arbor hole fits the widest range of 7-1/4 in. corded and cordless circular saws, making this blade a versatile drop-in replacement for demolition applications.
• 8,300 RPM Maximum Speed - rated for high-speed operation, this blade keeps pace with fast-moving professional workflows without compromising safety margins on corded or cordless saws.
• HW (Hard Metal / Carbide) Tooth Material - carbide teeth withstand the shock of cutting through nail-embedded wood and rough demolition materials, holding an edge far longer than standard steel-tipped blades.

Why This Product

• If you regularly cut through wood with embedded or partially loose nails, this blade was specifically tested under those exact conditions - not the easier, fully embedded nail test used by many competing products - giving you a blade that reflects real demolition site performance.
• The patented low mass plate design directly addresses one of the biggest pain points with cordless circular saws: battery life. By reducing blade mass and heat, the blade draws less energy per cut, stretching runtime and reducing recharging interruptions on the job.
• At 24 teeth with an ATB grind and a 5 deg. hook angle, this blade balances fast ripping speed with enough tooth geometry to handle crosscuts in demolition lumber, OSB, laminated beams, and pressure-treated material - reducing the need to swap blades mid-job.
• The Orange Shield protective coating and HW carbide construction are engineered for the longest possible tool life under demanding demolition conditions, lowering the cost-per-cut compared to blades that dull or corrode more quickly in rough environments.

Frequently Asked Questions

What makes the CMT Xtreme Demolition blade different from standard demo blades?

CMT tested this blade in a loose nail application, meaning nails were free to move slightly during cutting. This is a more demanding condition than the fully embedded nail tests that many competitors use, where nails are held solidly in place by surrounding wood. The result is a blade designed to perform under real demolition site conditions rather than controlled lab scenarios.

Is this blade compatible with cordless circular saws?

Yes. The patented low mass plate design was specifically developed to reduce blade mass and minimize heat generation, both of which increase cutting efficiency and extend battery runtime on cordless circular saws. It is equally compatible with corded 7-1/4 in. circular saws.

What does the ATB 5 tooth grind mean for cutting performance?

ATB stands for Alternate Top Bevel. In this configuration, each successive tooth is beveled in the opposite direction at a 5 deg. angle. This geometry distributes cutting forces across alternating tooth faces, which helps reduce tear-out and maintains consistent cutting action through demolition materials including nail-embedded wood, OSB, and pressure-treated lumber.

What is the maximum RPM rating for this blade?

This blade is rated for a maximum of 8,300 RPM. Always verify that your saw's no-load RPM does not exceed this limit before use, and follow all safety guidelines provided by both the saw manufacturer and CMT.
