CMT 288.100.20H Industrial Scoring Conical Blade by CMT is a 100mm conical scoring blade engineered for industrial panel processing applications. Designed specifically for use on machines with vertical regulation of the scoring blade, this hardmetal-tipped blade delivers a precisely adjustable kerf from 3.1 to 4.0mm - giving operators the flexibility needed to match the scoring kerf to the kerf of thick main saw blades. The combined CO+ATB tooth geometry (conical profile with 5-degree alternate top bevel) pre-scores the bottom face of melamine, laminate, and coated panel materials before the main blade passes through, preventing chipping and tearout on finished surfaces.

Key Features

• Conical (CO) tooth profile with adjustable kerf from 3.1 to 4.0mm - moving the blade closer to or farther from the main blade shifts the kerf width, so one blade adapts to different panel cutting setups without requiring a blade swap.
• CO+ATB tooth geometry (conical grind combined with 5 deg. alternate top bevel) - the alternating top bevel slices cleanly through coated surfaces, reducing edge chipping on melamine and laminate faces.
• 20 hardmetal (HW) teeth at a 5 deg. cutting angle - tungsten carbide tipping handles repeated industrial-volume cuts through abrasive materials like melamine and laminated chipboard while retaining edge sharpness over extended production runs.
• 100mm blade diameter with 20mm bore - sized to fit the scoring arbors of panel sizing machines and sliding table saws that use vertical scoring adjustment, ensuring a direct fit without adapters.
• 2.5mm plate thickness - a robust steel body provides stability at operating speed, minimizing vibration and deflection for consistent, clean score lines.
• Suggested for use with thick kerf or panel sizing main blades - pairs correctly with the larger kerf of industrial panel sizing blades so the score line does not undercut or over-cut the main blade path.
• Vertical regulation compatibility - engineered for machines where the scoring blade height is adjusted vertically, giving precise depth control for optimal scoring performance on panels of varying thickness.

Why This Product

• The adjustable 3.1 to 4.0mm kerf range means this single scoring blade can be tuned to match the kerf of different thick-kerf main blades, reducing the need to stock multiple fixed-kerf scoring blades for different saw setups.
• Specifically recommended for melamine and laminates - two of the most chip-prone coated panel materials - so buyers processing double-sided melamine or laminate-faced board can expect clean, splinter-free bottom edges directly from the saw.
• The industrial HW (hardmetal/tungsten carbide) tipping is built for continuous production environments, not occasional use, making this blade appropriate for cabinet shops, furniture manufacturers, and industrial panel processing lines running high daily cut volumes.
• The CO+5ATB sharpening specification is designed to work cooperatively with panel sizing main blades rather than independently, meaning the score line is precisely coordinated with the main cut for consistent edge quality across the full panel thickness.

Frequently Asked Questions

What types of machines is this scoring blade designed for?

The CMT 288.100.20H is suggested for machines with vertical regulation of the scoring blade, such as panel sizing machines and sliding table saws that allow the height of the scoring unit to be adjusted vertically. This type of adjustment is necessary to set the correct scoring depth relative to the panel face.

How does the adjustable kerf work and what range does it cover?

The conical (CO) tooth profile creates an adjustable kerf by allowing the blade to be shifted laterally closer to or farther from the main blade. Moving the scoring blade inward narrows the effective kerf and moving it outward widens it. The kerf is adjustable from 3.1mm to 4.0mm, allowing the score width to be matched to the kerf of the main panel sizing blade in use.

What materials is this blade designed to score?

This blade is designed for scoring melamine and laminates - coated panel materials that are prone to surface chipping when cut without a properly matched scoring blade. The CO+ATB tooth geometry is specifically suited to slicing cleanly through these coated surfaces before the main blade completes the cut.

What main blade should I pair with this scoring blade?

CMT recommends pairing the 288.100.20H with a thick kerf or panel sizing main blade. The adjustable 3.1 to 4.0mm kerf range of this scoring blade is intended to accommodate the wider kerf produced by industrial panel sizing blades, ensuring the score line aligns correctly with the full width of the main blade cut.
