CMT Industrial Adjustable Scoring Blade - 100 x 22mm, 10+10 Teeth is a precision conical scoring blade engineered for industrial panel processing. Designed to produce a clean, chip-free score line ahead of the main saw blade, this adjustable scoring blade is the right tool when working with melamine-coated boards, double-sided laminates, and veneered panels on machines with vertical regulation of the scoring blade. The kerf width adjusts from 2.8mm to 3.6mm, allowing operators to match the score line precisely to any thick-kerf or panel sizing blade in use. With a carbide-tipped flat top tooth geometry and a 12 deg. cutting angle, this blade delivers the consistent, flat-bottomed scoring cuts that demanding production environments require.

Key Features

• Adjustable conical two-half design (10+10 teeth): The blade separates into two adjustable halves, allowing the kerf to be dialed in anywhere from 2.8mm to 3.6mm - so the score width can be matched precisely to a thick-kerf or panel sizing main blade, eliminating edge tearout on melamine and laminates.
• Flat top tooth geometry (FLAT sharpening): Produces a flat-bottomed scoring groove, which means the score line meets the main blade cut cleanly and leaves no uncut fibers along the bottom edge - critical for achieving professional finish quality on laminated panels.
• 12 deg. cutting angle: This hook angle is optimized for scoring dense laminated surfaces, providing controlled aggression that initiates a clean cut without lifting or chipping the decorative face.
• HW (tungsten carbide) tooth material: Carbide tipped teeth maintain cutting sharpness through extended production runs on abrasive laminate and chipboard materials, reducing the frequency of blade changes on high-volume panel lines.
• 100mm diameter with 22mm bore: Compact scoring blade diameter paired with a standard 22mm bore fits the scoring arbor of machines designed with vertical scoring blade regulation, ensuring straightforward installation on compatible panel saws.
• Pin hole dimension 2/3.1 - 3.8/32: The integrated pin hole configuration provides positive rotational registration during adjustment, keeping both halves aligned during setup and throughout the cutting cycle.
• Suggested for use with thick-kerf or panel sizing blades: Purpose-matched to production-grade main blades, this scoring blade is intended to work as part of a complete two-blade cutting system for clean, industrial-quality panel sizing results.

Why This Product

• The adjustable kerf range of 2.8mm to 3.6mm means a single scoring blade can be tuned to match a variety of main blades without purchasing a separate fixed-kerf scorer for each setup - reducing tooling inventory on multi-blade machines.
• Specifically designed for machines with vertical regulation of the scoring blade, this blade integrates cleanly into the adjustment mechanism of compatible panel sizing saws and sliding table saws, avoiding the fitment issues that arise from using non-rated scoring blades.
• For shops processing melamine, double-faced laminates, and veneered sheet goods, a properly matched scoring blade is the primary defense against face chipping - and the flat top grind on this blade is the geometry that delivers the flat-bottomed groove needed for that clean result.
• With 10+10 carbide teeth and a compact 100mm diameter, this scoring blade is built for the sustained duty cycles of industrial panel processing, where tooth durability and consistent geometry directly affect finished panel quality and throughput.

Frequently Asked Questions

What type of machine is this scoring blade designed for?

This blade is suggested for machines with vertical regulation of the scoring blade, such as panel sizing saws equipped with a dedicated scoring arbor that adjusts vertically to set scoring depth independently of the main blade.

How does the adjustable kerf work on this blade?

The blade is a conical two-half design with 10 teeth on each half. The two halves are separated or brought closer together along the scoring arbor to vary the total kerf width anywhere in the range of 0.110 in. to 0.141 in. (2.8mm to 3.6mm), allowing the operator to match the score groove width to the kerf of the main blade being used.

What materials is this scoring blade rated to cut?

This blade is designed for melamine and laminates - including double-sided laminate panels, veneered sheet goods, and similar faced panel products where a chip-free scored edge is required on the underface before the main blade completes the cut.

What is the significance of the flat top tooth grind for scoring?

The flat top (FLAT) sharpening geometry creates a flat-bottomed score groove. This is important because a flat groove bottom aligns cleanly with the main saw blade's cutting plane, ensuring the two cuts meet without leaving uncut material along the bottom of the kerf, which is what prevents chipping and tearout on the decorative face of laminated or melamine panels.
