CMT 225.672.10 Non-Ferrous Metal and Melamine Saw Blade is an industrial-grade circular saw blade engineered for heavy-duty cutting of aluminum, brass, copper, PVC, and other non-ferrous metals. Built around an 80-tooth Triple Chip Grind geometry with a -6 deg. negative hook angle, this 10-inch blade delivers smooth, burr-free results in thick-walled extrusions, melamine panels, and non-ferrous stock - making it a go-to choice for fabricators and woodworkers who demand clean edges and reliable performance in demanding production environments.

Key Features

• 80-Tooth Triple Chip Grind (TCG) geometry - the alternating flat and chamfered tooth pattern shears through non-ferrous metals and melamine cleanly, minimizing chipping and producing smooth, finished edges that require little to no secondary cleanup.
• -6 deg. negative hook angle - actively reduces material grab and kickback risk during cuts in aluminum, copper, brass, and PVC, giving the operator greater control and a safer cutting experience on both thin- and thick-walled extrusions.
• 0.126-inch kerf thickness with a 0.098-inch plate - the generous kerf-to-plate ratio provides blade stability and reduces deflection during heavy-duty cuts, resulting in straighter, more consistent cuts through thick non-ferrous stock.
• HW (tungsten carbide) tooth material - carbide-tipped teeth retain their cutting edge longer than standard steel under the abrasive conditions of aluminum and copper cutting, extending service life between sharpenings.
• 15.88mm (5/8-inch) bore diameter - fits standard arbors on table saws, miter saws, and radial arm saws without adapters, simplifying blade changes across common shop machines.
• 7,600 RPM maximum rated speed - rated for the high-speed demands of radial arm saws, miter saws, and table saws, ensuring the blade can keep pace with production-rate cutting schedules without safety concern.
• TCG sharpening profile - the triple chip grind is specifically optimized for non-ferrous metals and melamine, reducing heat buildup and preventing the smearing or tearing that can occur with standard ATB profiles on these materials.

Why This Product

• Designed specifically for heavy-duty cutting of thick-walled aluminum extrusions, brass, copper, and PVC - materials that can damage or prematurely dull blades not purpose-built for non-ferrous applications.
• The combination of 80 teeth, TCG geometry, and a -6 deg. negative hook angle makes this blade equally capable on melamine panels and non-ferrous metals, reducing the need to swap blades between material types in mixed-material shops.
• Rated to 7,600 RPM and compatible with radial arm saws, miter saws, table saws, and special saws - this blade transitions seamlessly between stationary and sliding machines without requiring a separate blade for each setup.
• The industrial-grade HW carbide tips and TCG profile are built for production environments where consistent, burr-free results in aluminum, copper, and PVC are required repeatedly across high-volume cutting cycles.

Frequently Asked Questions

Why does this blade use a negative hook angle for cutting aluminum and non-ferrous metals?

The -6 deg. negative hook angle is specifically designed to reduce material grab and prevent the blade from self-feeding aggressively into softer non-ferrous metals like aluminum, brass, and copper. This produces a safer, more controlled cut and is a standard design choice for blades intended for metals and melamine.

Can this blade cut both thick-walled and thin-walled aluminum extrusions?

Yes. According to the product data, this blade is excellent on thick-walled extrusions and also good on thin-walled extrusions, making it a versatile choice for fabricators working with a range of aluminum profiles and non-ferrous stock.

What is a Triple Chip Grind (TCG) and why is it preferred for non-ferrous metals and melamine?

TCG, or Triple Chip Grind, alternates between a flat-top tooth and a trapezoidal (chamfered) tooth. This pattern scores and clears material efficiently, reducing heat buildup and producing cleaner cuts with minimal burring - benefits that are especially important when cutting aluminum, copper, PVC, and melamine where surface finish quality matters.

Which machines is this blade compatible with?

This blade is designed for use on radial arm saws, miter saws, table saws, and special saws. It has a 15.88mm (5/8-inch) bore and is rated to a maximum of 7,600 RPM, so it should always be confirmed that the machine's arbor size and RPM rating are within these specifications before use.
