CMT Ultra Finish Sliding Compound Saw Blade - 12" x 1", 90-Tooth is a professional-grade circular saw blade engineered for fine finish crosscuts on sliding compound miter saws and radial arm saws. Built with a premium harmonic steel plate, Orange Shield non-stick PTFE coating, and a precision-ground 4 Hi-ATB + 1 TCG tooth geometry, this 90-tooth blade delivers splinter-free results in softwood, hardwood, plywood, and double-sided laminate. The -5 deg. negative hook angle actively limits material climbing and tearout, making this an ideal solution for production woodworking environments and professional finish carpentry where cut quality cannot be compromised.

Key Features

• 90-Tooth Blade Configuration - a high tooth count spreads cutting load across more edges simultaneously, producing finer, cleaner crosscuts with minimal sanding or secondary finishing required.
• 4 Hi-ATB 30 deg. + 1 TCG Tooth Grind (Hi-ATB+TCG) - the combination of four high alternate top bevel teeth followed by one triple chip grind tooth slices fibers cleanly on both faces of the workpiece, making this pattern well-suited for plywood and double-sided laminate where both surfaces must remain chip-free.
• -5 deg. Negative Hook Angle - reduces the tendency of the blade to climb or grab the material during the cut stroke, giving the operator better control and limiting splintering on delicate or finished surfaces.
• Orange Shield Non-Stick PTFE Coating - protects the blade plate from corrosion, resin adhesion, and heat buildup, reducing drag through the cut and extending the usable life of the blade under heavy daily use.
• 0.122" Kerf with 0.100" Plate Thickness - a thin kerf relative to the plate provides adequate set for smooth cutting while minimizing material waste and reducing the load placed on the saw motor.
• 25.4mm (1") Bore Diameter - sized to fit the standard arbor used on sliding compound miter saws and radial arm saws without requiring additional adapters in most configurations.
• 6,400 Maximum RPM Rating - rated for the higher spindle speeds common on sliding compound miter saws, ensuring safe operation at the machine's design speed.
• Hardmetal (HW) Tooth Material - tungsten carbide-tipped teeth hold a sharp edge longer than standard steel, reducing the frequency of blade changes and sharpening intervals in high-volume shop environments.

Why This Product

• The -5 deg. negative hook angle directly addresses one of the most common problems with sliding compound miter saw cuts - blade climb and surface splintering - making this blade a dependable choice for finish-quality crosscuts in hardwood and softwood trim work.
• The Hi-ATB+TCG tooth pattern is specifically designed to produce clean cuts on both faces of double-sided laminate and plywood, eliminating the need to score or flip the panel before cutting.
• With a 6,400 RPM maximum rating, this blade is engineered to match the operating speeds of sliding compound miter saws and radial arm saws rather than being limited to slower-speed tools, making it a purpose-built rather than a generic crosscut option.
• The combination of the PTFE coating, thin kerf, and 90-tooth count reduces heat generation and cutting resistance, which translates to less resin buildup on the teeth and longer intervals between cleanings and sharpenings in daily production use.

Frequently Asked Questions

What machines is this blade compatible with?

This blade is designed for use on radial arm saws and sliding compound miter saws. The 1" bore diameter and 6,400 RPM rating are matched to the arbor and spindle speeds typical of these machines.

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

The -5 deg. negative hook angle is intentional for crosscutting applications. A negative hook angle limits the blade's tendency to climb into the workpiece during the cut stroke, which reduces splintering and gives the operator more controlled, predictable feed behavior - particularly important when using a sliding compound miter saw where the blade moves toward the operator.

What does the Hi-ATB+TCG tooth pattern mean in practical terms?

The pattern alternates four high alternate top bevel (Hi-ATB) teeth with one triple chip grind (TCG) tooth. The Hi-ATB teeth slice material fibers cleanly at the cut edges, while the TCG tooth clears chips from the kerf. Together, this geometry is well suited to materials like double-sided laminate and plywood where both the top and bottom face of the panel must remain free of tearout.

Can this blade be resharpened?

Yes. The blade uses hardmetal (tungsten carbide) tipped teeth with a specified grind of 4 Hi-ATB 30 deg. + 1 TCG, which is a standard professional sharpening pattern that qualified saw sharpening services can reproduce. The PTFE coating on the plate also helps preserve the body between sharpening cycles by resisting resin and corrosion buildup.
