The CMT 225.060.08 Non-Ferrous Metal and Melamine Saw Blade is a heavy-duty 8-1/2 in. x 5/8 in. circular saw blade engineered for precision cutting in aluminum, brass, copper, PVC, and other non-ferrous metals. Featuring a 60-tooth Triple Chip Grind (TCG) geometry and a -7 deg. negative hook angle, this blade is purpose-built to prevent material grabbing and deliver clean, burr-free results in both thick-walled and thin-walled extrusions. Whether you are cross-cutting aluminum profiles on a miter saw or ripping brass stock on a table saw, this CMT blade offers the tooth configuration and cutting geometry that non-ferrous metalworking demands.

Key Features

• 60-Tooth Triple Chip Grind (TCG) Geometry - the alternating flat and chamfered tooth pattern shears cleanly through non-ferrous metals and PVC without chipping, producing smooth, professional-quality cut edges that require minimal finishing.
• -7 deg. Negative Hook Angle - pulls away from the workpiece rather than aggressively biting into it, reducing the risk of kickback and material grabbing when cutting aluminum, copper, or brass profiles.
• 8-1/2 in. Diameter with 60 Teeth - a high tooth count on a compact-diameter blade means more teeth in contact per inch of cut, resulting in finer, cleaner cuts through both thick-walled and thin-walled extrusions.
• HW (Hard Metal / Tungsten Carbide) Tooth Material - carbide-tipped teeth maintain a sharp cutting edge through extended use in abrasive non-ferrous metals, extending blade service life compared to standard steel teeth.
• 0.122 in. Kerf with 0.100 in. Plate - the kerf-to-plate ratio provides adequate side clearance to prevent binding in the cut while minimizing material waste during each pass.
• 9,000 Maximum RPM Rating - rated for high-speed operation on radial arm saws, miter saws, table saws, and special saws, giving you flexibility across multiple machine types in a professional shop environment.
• 5/8 in. Bore (15.88 mm) - standard arbor size fits directly onto most miter saws, table saws, and radial arm saws without requiring adapters, simplifying blade changes and setup time.

Why This Product

• Designed specifically for heavy-duty cutting of thick-walled aluminum, copper, brass, and PVC extrusions - the TCG tooth geometry and negative hook angle work together to handle demanding non-ferrous applications where standard woodcutting blades would grab, chatter, or produce ragged edges.
• Rated to 9,000 RPM and compatible with radial arm saws, miter saws, table saws, and special saws - this single blade transitions easily between machine types, making it a practical choice for shops that need one reliable non-ferrous blade across multiple setups.
• The 60-tooth count in an 8-1/2 in. diameter delivers a high teeth-per-inch ratio that is well suited for both thick-walled and thin-walled extrusions, giving fabricators a versatile cutting solution without switching blades between material thicknesses.
• Carbide (HW) tipped teeth resist wear in abrasive non-ferrous metals - translating to fewer blade changes, lower long-term tooling costs, and consistent cut quality across production runs in aluminum, brass, copper, and PVC cutting applications.

Frequently Asked Questions

What materials can this saw blade cut?

This blade is designed to cut aluminum, brass, copper, PVC, and non-ferrous metals. It performs excellently on thick-walled extrusions and is also suitable for thin-walled extrusions. It is not intended for use on ferrous metals such as steel or iron.

Which machines is this blade compatible with?

This 8-1/2 in. blade with a 5/8 in. bore is compatible with radial arm saws, miter saws, table saws, and special saws. Always confirm your saw accepts an 8-1/2 in. blade diameter and a 5/8 in. arbor before installation.

Why does this blade use a negative hook angle instead of a positive one?

The -7 deg. negative hook angle causes the tooth to pull away from the workpiece during the cut rather than aggressively feeding into it. This is critical for non-ferrous metals because a positive hook angle can cause the blade to grab the material, creating dangerous kickback or rough, torn edges. The negative geometry produces a controlled, stable cut in aluminum, copper, brass, and PVC.

What does TCG (Triple Chip Grind) tooth geometry mean, and why does it matter for non-ferrous cutting?

TCG stands for Triple Chip Grind, a tooth pattern that alternates between a flat-top tooth and a chamfered (angled) tooth. This configuration allows the chamfered tooth to score the material first and the flat tooth to clear the chip cleanly, producing smooth, burr-free edges in hard or brittle non-ferrous materials like aluminum and brass. It also helps prevent tooth chipping when cutting harder non-ferrous alloys.
