CMT Industrial Scoring Conical Blade 160 x 4.3-5.5 x 55mm T36 CO+FLAT by CMT is a professional-grade conical scoring saw blade engineered for chip-free, clean-edged cuts through melamine, double-sided laminate, and veneered panel materials. Designed specifically for panel sizing machines with vertical regulation of the scoring blade, this 160mm diameter blade pairs a conical tooth geometry with a CO+FLAT sharpening profile to produce a perfectly flat-bottomed score line - eliminating tearout before the main blade passes through. With 36 carbide teeth and a wide 55mm bore, it is the right match for industrial wide-arbor panel sizing setups that demand repeatable, production-quality results.

Key Features

• 160mm Diameter with 36 Carbide Teeth (HW): The combination of blade diameter and tooth count delivers smooth, consistent scoring passes at production speed - reducing the risk of chipping on finished panel faces.
• CO+FLAT Tooth Geometry: The conical plus flat-top sharpening profile creates a flat-bottomed kerf that matches the main cutting blade's path - producing clean, chip-free edges on melamine and laminate without secondary finishing.
• Adjustable Kerf Width - 4.3 to 5.5mm: The conical blade design allows operators to dial in the exact kerf thickness to match thick-kerf or panel sizing main blades - ensuring precise alignment and eliminating edge defects.
• 55mm Bore with Pin Holes 3/7/66 + 3/6/84: The wide-bore configuration with dual pin hole patterns allows the blade to mount securely on a wide range of industrial panel saw arbors - improving stability and reducing vibration during the scoring pass.
• 3.2mm Plate Thickness: A rigid body plate minimizes blade deflection at scoring depth - maintaining a straight, consistent cut line across the full panel width.
• 10 deg. Cutting Angle: The hook angle is optimized for scoring applications - promoting clean shearing action through laminated surfaces rather than aggressive ripping that can crack or chip brittle face materials.
• Suggested for Machines with Vertical Regulation of Scoring Blade: Purpose-built for machines where scoring height is adjusted vertically - allowing precise depth control that prevents over-scoring while fully protecting the panel's decorative face.

Why This Product

• Purpose-matched for laminate and melamine panel sizing: Conical scoring blades are specifically designed to pre-score laminated panels ahead of the main saw blade, and the CO+FLAT geometry on this blade is tailored precisely for that task - making it a direct fit for shops cutting double-sided laminate and melamine board daily.
• Kerf adjustability eliminates guesswork when pairing blades: The 4.3 to 5.5mm adjustable kerf range means this scoring blade can be tuned to match the kerf of a thick-kerf panel sizing main blade - removing the trial-and-error that often leads to stepped or misaligned score lines.
• Dual pin hole pattern supports a wide range of industrial panel saws: With pin holes at 3/7/66 and 3/6/84, this blade accommodates multiple arbor configurations, reducing the need to source different hardware for different machines in a multi-saw facility.
• HW carbide construction for demanding production environments: Hard metal (HW) carbide tips withstand the abrasive demands of cutting melamine and laminate repeatedly - holding a sharp edge longer and reducing downtime spent resharpening or replacing worn tooling.

Frequently Asked Questions

What type of machine is this scoring blade designed for?

This blade is suggested for panel sizing machines with vertical regulation of the scoring blade. That style of machine allows the operator to set scoring depth by adjusting the blade height vertically, giving precise control over how deeply the conical blade pre-scores the panel surface before the main cutting blade passes through.

What is the difference between the CO+FLAT sharpening and a standard conical grind?

CO+FLAT combines a conical tooth profile with a flat-top component. The conical geometry allows the kerf width to be adjusted by raising or lowering the blade, while the flat-top portion of the grind ensures the bottom of the score line is flat - creating a clean, level groove that matches the main blade's cut path and eliminates chipping on laminated or melamine-faced surfaces.

How does the kerf range of 4.3 to 5.5mm work on a conical blade?

On a conical scoring blade, the tooth sides are angled rather than parallel. This means the effective kerf width changes depending on how deep the blade is set. Raising the blade increases the kerf width toward 5.5mm, while lowering it narrows the kerf toward 4.3mm. This adjustment allows the scoring kerf to be matched precisely to the kerf of the main panel sizing blade being used alongside it.

Is this blade compatible with arbors that use different pin hole configurations?

Yes. This blade includes both 3/7/66 and 3/6/84 pin hole patterns, which accommodates a wider range of industrial panel saw arbor configurations. Always verify your machine's specific arbor dimensions, bore size requirements, and pin hole pattern against the blade's specifications before mounting.
