CMT Industrial Adjustable Scoring Blade - 100 x 20mm, T10+10 Flat is a precision-engineered scoring saw blade designed for industrial panel sizing applications where chip-free cuts on laminated and veneered surfaces are essential. Built with a two-piece adjustable design and a flat top grind geometry, this CMT scoring blade delivers a clean, controlled pre-score on melamine, double-sided laminate, and veneered panels before the main blade passes through - eliminating tearout on even the most demanding finished surfaces. The 100mm diameter and 20mm bore make it a direct fit for panel sizing machines and sliding table saws used in cabinetmaking, furniture manufacturing, and high-volume panel processing.

Key Features

• Adjustable kerf width from 2.8 to 3.6mm - allows the scoring kerf to be precisely matched to the main blade, ensuring a seamless pre-score that prevents surface tearout regardless of the main blade's kerf dimension.
• Two-piece adjustable half design (10+10 teeth) - the blade consists of two independently adjustable halves, giving operators flexibility to fine-tune the cutting width for different main blades without changing the scoring unit.
• Flat top grind (FLAT) tooth geometry - produces flat-bottomed scoring cuts that create a clean, defined groove on the panel face, leaving a smooth, chip-free surface ready for the primary cut.
• 100mm blade diameter with 20mm bore - compact sizing is purpose-built for the scoring unit position on panel sizing machines and sliding table saws, fitting standard arbors in industrial woodworking setups.
• 12 deg. cutting angle - the hook angle is optimized for scoring cuts, providing efficient material engagement on coated and laminated panel surfaces without excessive force or chipping.
• Hardmetal (HW) tooth material - tungsten carbide-tipped teeth deliver extended cutting life on abrasive laminated surfaces, reducing downtime and resharpening frequency in high-production environments.
• Pin hole specification 2/3.1 - 3.8/32 - the blade includes pin hole configurations that ensure positive, precise positioning on the saw arbor for consistent, repeatable scoring results.

Why This Product

• Eliminates tearout on laminated panels - the flat top grind combined with the adjustable kerf is specifically engineered to pre-score coated surfaces like melamine and double-sided laminate before the main blade cuts through, making it the correct tool for chip-free panel sizing work.
• One scoring unit adapts to multiple main blades - the 2.8 to 3.6mm adjustable kerf range means a single scoring blade can be matched to different main blade kerfs, reducing the need to stock multiple fixed-width scoring blades.
• Hardmetal tips extend service life on abrasive materials - HW (tungsten carbide) teeth resist the wear caused by high-pressure laminate, melamine, and chipboard coatings, making this blade a practical choice for continuous production use.
• Industry-standard geometry for panel sizing machines - the 100mm diameter, 20mm bore, and T10+10 configuration align with the standard requirements of sliding table saws and industrial panel sizing machines, enabling straightforward installation without adapter hardware.

Frequently Asked Questions

What is the kerf adjustment range on this scoring blade?

The blade adjusts from 2.8mm to 3.6mm kerf width. This is achieved by spreading or closing the two adjustable halves of the blade apart on the arbor, allowing the scoring kerf to be matched precisely to the main saw blade being used.

What tooth grind does this scoring blade use, and why does it matter?

This blade uses a flat top grind (FLAT). This geometry creates a flat-bottomed pre-score groove in the panel surface, which is the correct profile for chip-free cutting on laminated, melamine, and veneered panels prior to the main blade completing the cut.

What machines is this 100mm scoring blade compatible with?

This blade is designed for use on panel sizing machines and sliding table saws that accept a 100mm diameter scoring blade with a 20mm bore. It is intended for the scoring unit position - not the main blade position - on these machines.

What tooth material is used on this scoring blade, and what surfaces can it handle?

The teeth are made from HW material (hardmetal / tungsten carbide). This makes the blade suitable for scoring abrasive coated panel materials including melamine, double-sided laminate, veneered panels, chipboard, and MDF.
