CMT Industrial Scoring Conical Blade 125 x 20mm T24 CO+ATB is a precision-engineered scoring blade built for demanding panel processing environments. Designed with a conical tooth geometry and a CO+ATB (Conical plus 5 deg. Alternate Top Bevel) grind, this 24-tooth blade delivers chip-free scoring on melamine, double-sided laminates, and coated panel surfaces before the main ripping blade makes its pass. With an adjustable kerf range of 3.1 - 4.0mm and a 125mm diameter, it is suited for industrial panel sizing operations where surface quality and production consistency are critical.

Key Features

• Conical tooth geometry (CO+ATB) at 5 deg. cutting angle - the conical profile allows the kerf width to be adjusted by raising or lowering the blade, enabling a precise pre-score that prevents surface tear-out on melamine and laminate panels without changing blades.
• Adjustable kerf range of 3.1 - 4.0mm - matches the kerf of a wide variety of thick-kerf main ripping or panel sizing blades, giving operators flexibility to tune the score width to their specific setup.
• 24 hardmetal (HW) teeth - carbide-tipped teeth maintain sharpness through extended production runs on abrasive coated materials like melamine and high-pressure laminate.
• 125mm blade diameter with 20mm bore - compact scoring blade diameter keeps the scoring unit low-profile while the 20mm bore fits the arbors found on most industrial panel sizing machines.
• 2.5mm plate thickness - a rigid, precision-ground steel plate minimizes vibration and lateral deflection during high-feed-rate panel sizing, contributing to a clean, accurate score line.
• Suggested for machines with vertical regulation of the scoring blade - optimized for panel sizing machines that allow vertical height adjustment of the scoring unit, enabling fine-tuning of the conical kerf width at the machine.

Why This Product

• For shops and production facilities processing melamine or laminated panels, the conical tooth design solves the problem of chipping on both the top and bottom panel faces - a common issue when scoring with a conventional flat-ground blade.
• The 3.1 - 4.0mm adjustable kerf range makes this blade compatible with thick-kerf and panel sizing main blades, reducing the need for multiple scoring blades across different saw setups.
• With 24 hardmetal teeth and an industrial-grade CO+ATB grind, this blade is built for continuous production use on coated wood-based panels, including chipboard, MDF with laminate, and veneered surfaces.
• Designed specifically for panel sizing machines with vertical blade regulation, this blade takes full advantage of the machine's adjustment mechanism - giving operators direct control over score width without swapping tooling.

Frequently Asked Questions

What type of machine is this scoring blade designed for?

This blade is suggested for use on panel sizing machines with vertical regulation of the scoring blade. The vertical adjustment capability is what allows the operator to fine-tune the conical kerf width to match the main ripping blade.

What does the conical (CO) tooth geometry do, and why does it matter?

The conical grind means the sides of each tooth are angled, so raising or lowering the blade changes the effective kerf width. This allows the score kerf to be set between 3.1mm and 4.0mm to match the main blade's kerf without swapping tooling, which is essential for chip-free cuts on melamine and laminate panels.

What materials can this blade score cleanly?

This blade is designed for melamine-coated panels, double-sided laminates, veneered panels, chipboard, and MDF. The CO+ATB tooth geometry creates a clean pre-score on coated surfaces to prevent edge chipping when the main panel sizing blade completes the cut.

Should this blade be used with a specific type of main ripping blade?

Yes - it is suggested for use with a thick-kerf or panel sizing main blade. The 3.1 - 4.0mm adjustable kerf range is intended to align with the kerf of industrial-grade main blades commonly used in panel sizing operations.
