The CMT 289.120.24T Industrial Adjustable Scoring Blade is a precision-engineered 120mm conical scoring blade designed for industrial panel sizing operations. Built by CMT for demanding production environments, this blade features a 12+12 tooth configuration across two independently adjustable halves, allowing operators to dial in the exact kerf width needed for chip-free cuts on melamine, laminates, and veneered panel materials. The 50mm bore diameter and flat tooth geometry make it a reliable companion to thick-kerf panel sizing blades, delivering clean, tear-free scores on both faces of laminated sheet goods before the main blade passes through.

Key Features

• Adjustable kerf width from 2.8mm to 3.6mm - lets operators match the scoring kerf precisely to the main blade kerf, eliminating chipping on both sides of the cut without swapping blades
• 12+12 tooth two-half adjustable design - the dual-half construction allows independent lateral adjustment of each half, giving machinists fine control over kerf width in a single setup
• 120mm blade diameter with 50mm bore - sized specifically for industrial panel sizing machines with wide arbor configurations, ensuring secure, concentric mounting during high-speed production runs
• Flat tooth geometry (FLAT sharpening) - produces a clean, consistent score line across melamine and laminate surfaces, reducing delamination and surface tear-out
• 12 deg. cutting angle - optimized hook geometry for smooth entry into laminated panels, reducing feed resistance and extending tooth life in continuous production use
• Hardmetal (HW) carbide tipped construction - industrial-grade carbide maintains sharp cutting edges through extended production runs on abrasive laminate and melamine surfaces
• Suggested for machines with vertical regulation of the scoring blade - compatible with the adjustment systems found on purpose-built panel sizing equipment, simplifying height and depth setup

Why This Product

• Adjustable kerf eliminates the need for multiple fixed-width scoring blades - one blade covers a 2.8mm to 3.6mm range, making it practical for shops running different main blade kerfs on the same machine
• Specifically engineered for melamine and laminate panel sizing - the flat tooth grind and 12+12 tooth count work together to prevent surface chipping on the most demanding decorative panel materials
• Designed to pair with thick-kerf or panel sizing main blades - coordinating the scoring blade to the main blade is essential for double-sided chip-free cuts, and this blade is purpose-built for that role
• Industrial-class carbide (HW) construction supports high-volume production use - shops processing large quantities of laminated panels need a scoring blade that holds its edge through continuous cycling, which hardmetal carbide is designed to deliver

Frequently Asked Questions

How is the kerf width adjusted on this scoring blade?

The blade is built as two independent halves that can be shifted laterally relative to each other. By spreading or closing the two halves, the effective cutting width is changed anywhere within the 0.110 in. to 0.141 in. (2.8mm to 3.6mm) range. This lets operators match the scoring kerf to the kerf of the main panel sizing blade being used, ensuring a clean, chip-free cut on both faces of the panel.

What type of machine is this scoring blade designed for?

This blade is suggested for panel sizing machines that feature vertical regulation of the scoring blade. The 50mm bore diameter and the 4/6.2 - 10/62 pin hole configuration are intended for the wide arbor setups common on industrial panel sizing equipment.

What materials can this blade cut?

The CMT 289.120.24T is designed for cutting melamine-faced boards and laminate panels. The flat tooth geometry (FLAT sharpening) and 12 + 12 tooth count work together to score the surface cleanly before the main blade passes through, preventing delamination and chipping on both sides of decorative laminated sheet goods.

Should this scoring blade be used alone or with a main saw blade?

This blade is designed to be used in combination with a thick-kerf or panel sizing main blade. The scoring blade pre-cuts a shallow groove on the underside of the panel, so that when the main blade completes the cut from above, both surfaces remain chip-free and clean. It is not intended for use as a standalone ripping or crosscutting blade.
