CMT 288.300.48T Scoring Blade 300 x 50mm T48 by CMT is a heavy-duty industrial conical scoring blade engineered for chip-free cutting on melamine panels, double-sided laminates, and veneered sheet goods. With a 300mm (12 in.) diameter and 48 precision-ground teeth, this blade is built for high-throughput panel sizing operations where surface quality on coated materials is non-negotiable. The CO+FTG tooth geometry - combining conical grind with flat top geometry - produces clean, splinter-free scores ahead of the main saw blade, preserving the integrity of even the most delicate laminate surfaces.

Key Features

• 300mm (12 in.) Diameter with 48 Teeth - large-format scoring capacity means this blade handles full-size industrial panels without sacrificing tooth engagement or cut quality.
• CO+FTG Tooth Geometry (Conical + Flat Top) - the combined conical and flat-top grind shears laminate and melamine coatings cleanly from both faces, preventing chipping and tear-out on the panel surface.
• Kerf Range 4.3 to 5.5mm (0.169 in. - 0.217 in.) - adjustable scoring kerf width accommodates different main blade kerf sizes, allowing the scoring blade to be precisely matched to the primary cutting blade in use.
• 50mm Bore with Pin Hole 3/15/80 - the standard industrial bore size with pin hole configuration ensures secure, concentric mounting on compatible panel sizing machines, reducing runout for consistent scoring depth.
• HW (Tungsten Carbide) Tooth Material - carbide-tipped teeth retain a sharp cutting edge longer than standard steel, reducing re-sharpening frequency and downtime during production runs.
• 10 deg. Hook Angle - a positive 10 deg. cutting angle provides controlled, aggressive scoring on dense laminated and coated board materials without grabbing or vibration.
• Plate Thickness 0.126 in. (3.2mm) - a rigid, precision-ground plate minimizes blade flex at operating speed, contributing to a consistent and repeatable score depth across the full panel length.

Why This Product

• Built for machines with vertical scoring blade regulation - the 300mm diameter and industrial pin hole configuration (3/15/80) are specifically suited to panel sizing machines that adjust scoring blade height vertically, making it a direct-fit solution for that machine class.
• Eliminates chipping on coated panels - the CO+FTG geometry pre-cuts the laminate or melamine coating before the main blade passes through, which is the critical step that prevents edge chipping on double-sided laminated and veneered workpieces.
• Pairs with thick-kerf or panel sizing main blades - the 4.3 to 5.5mm adjustable kerf range is designed to complement thick-kerf main blades, giving operators the flexibility to dial in an exact match and avoid over- or under-cutting the score line.
• Carbide teeth designed for re-sharpening - the CO+FTG sharpening method (noted in the blade specifications) indicates these teeth are intended for professional resharpening, extending the service life of the blade and reducing total cost over time.

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. The 50mm bore with pin hole 3/15/80 and 300mm diameter are sized for industrial panel processing equipment that uses that configuration.

What does the CO+FTG tooth grind mean and why does it matter?

CO+FTG stands for Conical grind plus Flat Top Grind. The conical tooth profile slices through the laminate or melamine coating at an angle from both sides of the kerf, while the flat top geometry cleans the center of the score. Together, these grind profiles prevent chipping or tear-out on coated panel surfaces, which is essential when cutting melamine or double-sided laminated boards.

How do I match this scoring blade to my main saw blade?

The scoring blade has an adjustable kerf range of 4.3 to 5.5mm (0.169 in. - 0.217 in.), which allows you to widen or narrow the scoring cut to precisely match the kerf of your primary cutting blade. CMT suggests using this scoring blade with a thick-kerf or panel sizing main blade for best results.

Can this blade be resharpened?

Yes. The blade uses HW (tungsten carbide) teeth with a CO+FTG tooth geometry, which is a sharpenable grind type. Professional resharpening of the carbide teeth extends the usable service life of the blade, making it a cost-effective choice for high-volume panel processing operations.
