The CMT Dado Pro Set 8" FLAT+ATB is a professional-grade stacked dado set engineered for woodworkers who demand clean, flat-bottomed cuts across a wide range of materials. With a cutting width range of 1/4 in. to 13/16 in. and a -12 deg. hook angle, this set delivers virtually splinter-free dadoes, rabbets, grooves, and tongue-and-groove joints in solid wood, laminates, melamine, and veneered plywood. The combined ATB 20 deg. + FLAT tooth geometry of the outer blades and chippers works together to produce smooth sidewalls and perfectly flat groove bottoms - making it a trusted choice for cabinet making, shelving projects, and box joint work.

Key Features

• -12 deg. negative hook angle - reduces grab and chatter during cutting, resulting in a controlled, smooth feed through dense hardwoods and composite materials
• ATB 20 deg. + FLAT tooth configuration - the alternating top bevel outer blades shear the wood fibers cleanly at the groove walls while the flat chippers evacuate material efficiently for flat-bottomed results
• 1/4 in. to 13/16 in. adjustable cutting width - a single set handles the full range of standard dado, groove, and rabbet widths, eliminating the need for multiple dedicated cutters
• 8 in. blade diameter with 12+12 teeth - provides ample cutting depth capacity on stationary table saws and radial arm saws while maintaining tooth count for fine surface quality
• ORANGE SHIELD COATING - protects the carbide-tipped HW blades from heat build-up, gumming, and corrosion, extending blade life and maintaining cutting performance over time
• 5/8 in. bore diameter - fits the standard arbor found on most stationary table saws and radial arm saws, including SawStop cabinet saws, for broad machine compatibility
• Rated to 6000 RPM - suited for the operating speeds of common stationary woodworking machinery, supporting safe and reliable use in shop environments
• HW (carbide) material construction - tungsten carbide tipping stays sharp longer through abrasive materials like melamine and veneered plywood compared to high-speed steel alternatives

Why This Product

• The -12 deg. negative hook angle is specifically chosen for dado cutting - it prevents the set from self-feeding aggressively, giving the operator greater control when routing wide grooves in shelving and cabinet carcass work.
• Compatibility with SawStop table saws alongside most radial arm saws and stationary table saws means this dado set integrates into a wide variety of professional and shop setups without adapter hardware.
• The ORANGE SHIELD COATING addresses one of the most common maintenance frustrations with dado sets - resin and pitch build-up from cutting laminates and melamine - by actively protecting against gumming and corrosion.
• The combined ATB + FLAT tooth geometry handles both the scoring and clearing functions in a single pass, making it well-suited for demanding materials like veneered plywood where tear-out at groove edges is a concern.
