CMT Super Fine Finishing Sliding Compound Blade - 12" x 5/8" T90 is engineered for woodworkers and finish carpenters who demand ultra-smooth crosscuts on demanding materials. Designed for slide miter saws and radial arm saws, this 90-tooth carbide blade delivers the kind of clean, tearout-free results required when cutting hardwood, softwood, plywood, melamine, laminate, and molding. The advanced 4 ATB 20 deg. + 1 Flat tooth geometry combined with a -3 deg. negative hook angle controls the cut aggressively, reducing chip-out and producing glass-smooth surfaces that require little to no sanding.

Key Features

• 90-Tooth 4 ATB + 1 Flat Grind - the alternating top-bevel teeth shear fibers cleanly while the flat raker clears waste efficiently, resulting in ultra-fine surface quality on hardwood, softwood, plywood, melamine, laminate, and molding
• -3 deg. Negative Hook Angle - slows the blade's feed rate into the material, giving the teeth more control over each cut and dramatically reducing tearout on delicate finished surfaces
• 90 Teeth - a high tooth count means more cutting edges contact the material per revolution, producing exceptionally smooth cross-grain cuts with minimal splintering
• 0.118" Kerf with 0.098" Plate Thickness - the thin kerf removes less material per pass, reducing waste and strain on the saw motor while maintaining a stable, accurately guided cut
• Special Straightening and Balancing Processes - blade body flatness is obtained via special straightening processes that guarantee exceptionally reduced tolerances, and balancing performed on all saw blades guarantees maximum stability during operation
• Hardmetal (HW) Carbide Teeth - carbide construction resists heat and abrasion, extending edge life when cutting dense hardwoods, abrasive composites, melamine, and laminate
• 15.88 mm Bore (5/8") - standard bore diameter fits the arbors of most slide miter saws and radial arm saws without requiring an adapter
• 6,400 RPM Rating - matched to the high-speed requirements of sliding compound miter saws, ensuring safe, stable performance at full operational speed

Why This Product

• Finishing work on melamine, laminate, and pre-finished hardwood demands a blade that will not chip or splinter edges - the 90-tooth 4 ATB + 1 Flat configuration with a -3 deg. negative hook angle is purpose-built for exactly this application
• Slide miter saws operate at high blade speeds and require a blade rated and balanced for those conditions - the 6,400 RPM maximum rating and special balancing process mean this blade is matched to the machines it is designed for
• Thin-kerf geometry (0.118" kerf, 0.098" plate) reduces material waste on expensive hardwoods and finish panels, and puts less load on the saw, helping maintain accuracy throughout long workdays
• The special straightening processes that guarantee exceptionally reduced flatness tolerances translate directly to straighter, more repeatable cuts - critical when fitting molding, trim, or cabinetry where gaps are unacceptable

Frequently Asked Questions

What machines is this blade compatible with?

This blade is designed for use on slide miter saws and radial arm saws. The 15.88 mm (5/8") bore fits the standard arbors found on most of these machines, and the 6,400 RPM maximum rating matches the operational speeds of sliding compound miter saws.

Why does this blade use a negative hook angle?

The -3 deg. negative hook angle slows the rate at which the blade pulls itself into the material during a cut. This gives the operator more control and significantly reduces chip-out and tearout on sensitive finished surfaces such as melamine, laminate, and pre-finished hardwood - making it ideal for finish-quality crosscutting.

What does the 4 ATB + 1 Flat tooth grind mean in practice?

The grind pattern is 4 ATB 20 deg. + 1 Flat. Four alternating top-bevel teeth shear wood fibers cleanly on both sides of the cut, while the fifth flat-top raker tooth clears the kerf of debris. This combination produces an ultra-smooth cut surface while keeping the blade running efficiently - particularly valuable when cutting hardwood, plywood, molding, and laminate materials.

Is this blade suitable for cutting melamine and laminate without chipping?

Yes. The 90-tooth count, the -3 deg. negative hook angle, and the 4 ATB + 1 Flat carbide grind work together to minimize chip-out on both the top and bottom face of melamine and laminate panels. The high tooth count means more cutting edges engage the surface per revolution, distributing the cutting force and leaving a cleaner edge than lower-tooth-count blades.
