CMT 284.720.12 Thin Non-Ferrous Metal and Plastics Saw Blade is a 12-inch, 108-tooth circular saw blade engineered for industrial cutting of thin-walled aluminum, brass, copper, PVC, and other non-ferrous metals. With a Triple Chip Grind (TCG) tooth geometry and a 6 deg. cutting angle, this blade delivers clean, controlled cuts on radial arm saws, miter saws, table saws, and special sawing machines - making it a reliable choice for fabrication shops and production environments that demand precision and repeatability in non-ferrous stock cutting.

Key Features

• Triple Chip Grind (TCG) Tooth Geometry - alternating flat and chamfered teeth shear through aluminum, brass, copper, and PVC cleanly, reducing burrs and chipping on non-ferrous metals and plastic profiles for production-ready results.
• 108 Teeth on a 12-inch Plate - the high tooth count creates an extremely fine cut pitch, which is essential for thin-walled extrusions where a coarser blade would cause tear-out or deformation.
• 6 deg. Cutting Angle - a low positive hook angle keeps the blade feeding at a controlled rate, preventing grabbing or climbing when cutting non-ferrous metals and rigid PVC, improving operator safety and cut quality.
• 0.126-inch Kerf with a 0.098-inch Plate - the thin kerf removes minimal material per pass, reducing waste on expensive non-ferrous stock while the rigid plate maintains tracking stability at speed.
• 25.4mm (1-inch) Bore Diameter - fits standard 1-inch arbors found on radial arm saws, miter saws, table saws, and special saws without requiring adapters in most setups.
• 6,400 RPM Maximum Rating - rated for high-speed operation so the blade can be used at full machine speed on compatible equipment without risk of over-spinning.
• Hardened Metal (HW) Carbide Teeth - tungsten carbide cutting edges maintain sharpness longer in abrasive non-ferrous metals, extending the interval between resharpenings in heavy-duty cutting applications.
• Designed for Heavy-Duty Cutting - built to handle demanding industrial production environments including thick-walled extrusions, not just light-duty or occasional use tasks.

Why This Product

• Optimized for thin-walled aluminum and non-ferrous extrusions - the 108-tooth TCG grind is specifically suited for thin-walled extrusions where other blades leave rough edges or cause workpiece distortion, making this the purpose-built choice for aluminum fabrication and PVC profile cutting.
• Versatile machine compatibility - fits radial arm saws, miter saws, table saws, and special saws with a standard 1-inch bore, so one blade works across multiple machines in a shop environment without switching arbors or adapters.
• Thin kerf saves material on costly stock - at 0.126-inch kerf, this blade removes less material per cut than standard-kerf blades, which translates directly to less waste when processing expensive aluminum, brass, or copper stock.
• Rated at 6,400 RPM for high-production use - the high RPM rating means this blade keeps pace with industrial equipment in production environments, maintaining cutting performance through extended operation in heavy-duty non-ferrous cutting tasks.

Frequently Asked Questions

What materials can this 12-inch saw blade cut?

This blade is designed to cut aluminum, brass, copper, PVC, and non-ferrous metals. It is specifically engineered for thin-walled extrusions in industrial settings, and also performs well on thick-walled extrusions.

What machines is this blade compatible with?

The CMT 284.720.12 is compatible with radial arm saws, miter saws, table saws, and special saws that accept a standard 1-inch (25.4mm) arbor bore.

What is the maximum RPM for this blade?

This blade is rated for a maximum of 6,400 RPM. Always verify that your machine's operating speed does not exceed this rating before use.

Why is Triple Chip Grind (TCG) the right tooth geometry for non-ferrous metals and plastics?

TCG geometry alternates between flat-top teeth and chamfered teeth. The chamfered teeth score the material first, and the flat teeth remove the remaining chip cleanly. This sequence reduces burrs and surface chipping on non-ferrous metals like aluminum and brass as well as PVC, producing a cleaner finish than standard alternate-top-bevel grinds on these materials.
