CMT 225.728.18 Non-Ferrous Metal and Melamine Saw Blade is an industrial-grade 18 in. circular saw blade engineered for heavy-duty cutting of aluminum, brass, copper, PVC, and non-ferrous metals. Featuring 128 Triple Chip Grind (TCG) teeth and a -6 deg. negative hook angle, this large-diameter blade delivers smooth, controlled cuts on thick-walled extrusions, thin-walled extrusions, and melamine panels - making it a dependable choice for high-volume production and shop environments that demand consistent results from radial arm saws, miter saws, table saws, and special saws.

Key Features

• 128-Tooth TCG Tooth Grind - the Triple Chip Grind configuration is specifically designed for non-ferrous metals and melamine, producing clean, chip-free cuts that reduce finishing time and material waste.
• -6 deg. Negative Hook Angle - the negative cutting angle controls material feed rate and reduces grabbing during cuts through aluminum, copper, brass, and PVC, improving operator safety and cut quality.
• 18 in. (457mm) Blade Diameter - the large cutting diameter allows for deep crosscuts through thick-walled extrusions and wide non-ferrous stock, supporting heavy-duty industrial applications.
• 0.150 in. Kerf Thickness - engineered for rigid, stable cuts that minimize blade deflection through dense non-ferrous materials, helping maintain dimensional accuracy in production settings.
• 0.126 in. Plate Thickness - the thick plate body provides rigidity and vibration damping during high-load cuts through aluminum and copper profiles, contributing to longer blade service life.
• 25.4mm Bore Diameter - the precision-machined 1 in. bore fits standard arbors on radial arm saws, miter saws, table saws, and special saws, enabling straightforward installation without adapters.
• 4,200 Maximum RPM Rating - rated for 4,200 RPM, this blade is matched to the power output of industrial stationary and special saws used in non-ferrous metal fabrication shops.
• HW Carbide Tooth Material - hardmetal (HW) carbide tips deliver extended edge retention when cutting abrasive non-ferrous materials including aluminum, brass, copper, and PVC extrusions, reducing sharpening frequency.
• Heavy-Duty Industrial Classification (SBFKXT) - classified as an Industrial Xtreme non-ferrous metal, PVC, and melamine circular saw blade, this blade is built to perform in continuous production environments, not just occasional-use applications.

Why This Product

• Optimized for thick-walled non-ferrous extrusions - the combination of 128 TCG teeth, a -6 deg. negative hook angle, and an 18 in. diameter makes this blade excellent for cutting thick-walled aluminum, copper, and brass extrusions where standard blades struggle to maintain cut quality.
• Handles a broad range of non-ferrous and plastic materials - rated for aluminum, brass, copper, PVC, and other non-ferrous metals, this single blade covers multiple material types common in fabrication and manufacturing environments, reducing the need to swap blades between jobs.
• Compatible with multiple industrial machine types - designed for use on radial arm saws, miter saws, table saws, and special saws, this blade integrates into a variety of shop setups without requiring dedicated single-machine configurations.
• High tooth count for refined surface finish - with 128 teeth on an 18 in. blade, the cutting action produces finer surface quality on melamine panels and non-ferrous metals, reducing secondary processing steps after cutting.

Frequently Asked Questions

What materials can this CMT 18 in. saw blade cut?

This blade is designed to cut aluminum, brass, copper, PVC, and non-ferrous metals. It is also suitable for melamine panels. It is listed as excellent for heavy-duty cutting and thick-walled extrusions, and good on thin-walled extrusions.

What type of tooth grind does this blade use and why does it matter for non-ferrous cutting?

This blade uses a Triple Chip Grind (TCG) tooth profile. TCG is specifically suited for non-ferrous metals and hard plastics because the alternating tooth geometry helps clear chips efficiently and reduces heat build-up, supporting clean cuts through materials like aluminum, copper, and PVC.

What machines is the CMT 225.728.18 compatible with?

This blade is designed for use on radial arm saws, miter saws, table saws, and special saws. The 25.4mm (1 in.) bore and 18 in. diameter are suited to industrial machines capable of accommodating a large-format non-ferrous cutting blade.

What is the maximum RPM rating for this blade?

The CMT 225.728.18 is rated for a maximum of 4,200 RPM. Always verify that your machine's operating speed does not exceed this rating before mounting and using the blade, to ensure safe and proper operation.
