CMT Ultra Finish Sliding Compound Saw Blade 10" x 5/8" - 80 Tooth is a professional-grade circular saw blade from CMT, engineered for fine finish crosscutting on radial arm saws and sliding compound miter saws. Featuring an 80-tooth configuration with a 4 Hi-ATB 30 deg. plus 1 TCG tooth grind and a -5 deg. negative hook angle, this blade is purpose-built to deliver splinter-free, ultra-smooth cuts through hardwood, softwood, plywood, and double-sided laminate. The Orange Shield non-stick PTFE coating protects the plate from resin buildup, corrosion, and heat, extending blade life during intensive daily milling and finish carpentry work.

Key Features

• 80-Tooth Hi-ATB + TCG Grind (4 Hi-ATB 30 deg. + 1 TCG) - the alternating top bevel teeth score material fibers cleanly on entry and exit, while the triple chip grind tooth clears the gullet efficiently, resulting in ultra-smooth crosscut surfaces with minimal tearout on finished panels and laminates.
• -5 deg. Negative Hook Angle - limits the blade from "climbing" into the workpiece and dramatically reduces splintering, giving the operator greater control and a cleaner cut edge on double-sided laminate and delicate hardwood surfaces.
• Orange Shield Non-Stick PTFE Coating - shields the plate against rust, corrosion, and sticky resin deposits, reducing blade drag through the cut and helping the blade run cooler for longer cutting life between sharpenings.
• HW (Hard Metal / Carbide) Tooth Material - industrial-grade carbide tips hold a sharp edge longer under repeated crosscutting demands, reducing downtime and sharpening frequency in high-production shop environments.
• 0.122" Kerf / 0.100" Plate - the thin kerf-to-plate ratio removes less material per pass, reducing waste and motor load on radial arm saws and sliding compound miter saws while maintaining a stable, vibration-resistant cut.
• 7,600 Maximum RPM Rating - rated for the high-speed demands of sliding compound miter saws and radial arm saws, ensuring safe, consistent performance at the machine speeds these tools typically operate.
• 10" Diameter with 5/8" Bore (15.88mm) - the standard 10" diameter and 5/8" arbor bore ensure direct compatibility with the most common sliding compound miter saws and radial arm saws without requiring adapters.

Why This Product

• When fine finish crosscutting is the priority - such as cutting crown molding, cabinet panels, or double-sided laminate - the 80-tooth Hi-ATB configuration and -5 deg. negative hook angle work together to minimize splintering and climbing, delivering results that require little or no sanding.
• The PTFE-coated plate resists resin and heat buildup during repeated cuts, which means the blade stays cleaner and performs more consistently across a full workday without requiring frequent cleaning stops.
• With carbide (HW) tooth material and precision mirror-finish sharpening on every tooth, this blade is built for professional and industrial applications where cut quality and tool longevity are both non-negotiable requirements.
• The 7,600 RPM rating combined with a thin 0.100" plate makes this blade well suited for the high-cycle demands of sliding compound miter saws, where speed and precision must coexist during production crosscutting of hardwood and engineered wood products.

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. Its 10" diameter and 5/8" bore fit the standard arbor size found on most of these machine types without requiring an adapter.

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

The -5 deg. negative hook angle is specifically chosen for crosscutting applications on sliding and radial arm saws. It limits the blade from "climbing" aggressively into the workpiece, which reduces splintering and gives the operator more controlled, cleaner cuts - especially important when cutting double-sided laminate or finished hardwood panels.

What materials can this blade cut?

This blade is rated for cutting softwood, hardwood, plywood, and double-sided laminate. The 4 Hi-ATB 30 deg. plus 1 TCG tooth pattern is optimized for fine finish crosscutting across all of these material types.

What is the maximum safe operating speed for this blade?

The blade is rated for a maximum of 7,600 RPM. Always confirm your saw's operating speed does not exceed this rating before use to ensure safe operation.
