The CMT Heavy Duty Solid Surface Blade - 12" x 1" Bore, 84-Tooth MTCG is a professional-grade circular saw blade engineered for demanding cutting applications in solid surface panels, thick plastics, laminates, and panel materials. Featuring a Modified Triple Chip Grind (MTCG) tooth geometry and a 0 deg. cutting angle, this blade is purpose-built to deliver swirl-free, burn-free, and chip-free results on the dense, unforgiving materials that challenge standard saw blades. Whether you are fabricating countertops, machining plexiglass, or ripping vinyl sheet goods, this 84-tooth blade provides the smooth, precise finish quality that professional fabricators demand.

Key Features

• Modified Triple Chip Grind (MTCG) Tooth Geometry - the specialized MTCG grind alternates flat-top and chamfered teeth to shear cleanly through solid surface, thick plastic, and laminate without cracking or chipping, producing a finish-ready edge on every pass.
• 84 Carbide Teeth - the high tooth count slows chip load per tooth, which translates directly into smoother cut surfaces and reduced tearout on fragile or brittle panel materials, minimizing the need for secondary sanding or edge treatment.
• 0 deg. Cutting Angle (Hook Angle) - a zero-degree hook angle controls material feed rate and reduces the risk of grabbing or self-feeding, giving the operator better control and a safer cut on dense solid surface and thick plastic.
• 0.126" Kerf / 0.098" Plate Thickness - the precise kerf-to-plate ratio provides enough blade rigidity to resist deflection while removing only the material necessary, helping reduce waste on premium solid surface panels.
• 25.4mm (1") Bore Diameter - the standard 1-inch arbor bore fits directly onto radial arm saws, table saws, and special saws without requiring adapter bushings, saving setup time.
• 6,400 RPM Maximum Speed - rated for up to 6,400 RPM, this blade maintains structural integrity at the high spindle speeds common on table saws and radial arm saws used in solid surface fabrication shops.
• HW (Hard Metal / Carbide) Cutting Material - carbide-tipped teeth stay sharp significantly longer than high-speed steel alternatives when cutting abrasive materials such as solid surface, plexiglass, and plastic laminates, reducing frequency of blade changes.
• Orange Chrome Finish - the orange chrome coating on the blade plate helps resist material buildup and heat, keeping the plate clean during extended production runs.

Why This Product

• Solid surface panels and thick plastics are notoriously prone to cracking and chipping during sawing - the MTCG tooth form on this blade is specifically engineered to eliminate those failure modes, making it the right choice when a clean, swirl-free edge is required the first time.
• With 84 teeth and a 0 deg. hook angle working together, this blade produces the kind of finish-quality cuts on laminates and panel materials that reduce or eliminate the post-cut polishing and edge work that eats into shop productivity.
• A maximum speed rating of 6,400 RPM and a 12" diameter make this blade well matched to the radial arm saws, table saws, and special production saws used in commercial solid surface and plastic fabrication environments.
• The 1-inch bore fits standard arbors on professional stationary saws without adapters, and the blade is compatible with a broad range of cut materials - solid surface, wood panel material, laminate, plastic, plexiglass, and vinyl - making it a versatile production tool across multiple material types.

Frequently Asked Questions

What type of tooth grind does this blade use, and why does it matter for solid surface cutting?

This blade uses a Modified Triple Chip Grind (MTCG), which alternates between flat-top and chamfered teeth. This geometry is specifically designed to shear through dense solid surface panels, thick plastics, and laminates without cracking or chipping the material. The result is a clean, swirl-free, and burn-free cut edge that requires minimal finishing work.

Can this blade be used on a miter saw?

No. According to CMT, this blade is not recommended for use on miter saws. It is designed for use on radial arm saws, table saws, and special saws. Using it on an incompatible machine type could present a safety hazard.

What is the maximum RPM rating for this blade, and which machines is it compatible with?

This blade is rated for a maximum of 6,400 RPM. It is compatible with radial arm saws, table saws, and special saws equipped with a standard 1-inch (25.4mm) arbor. Always verify that your machine's RPM does not exceed the blade's maximum rated speed before use.

What materials can this blade cut beyond solid surface?

In addition to solid surface panels, this blade is designed to cut laminate, solid wood, panel material, plastic, thick plastic, plexiglass, and vinyl. The 84-tooth MTCG carbide-tipped blade handles a broad range of hard and abrasive materials common in countertop fabrication and millwork environments.
