CMT Industrial Panel Sizing Saw Blade - 430mm Diameter, 72-Tooth TCG, 80mm Bore, COMBI5 Pin Hole is an industrial-grade circular saw blade engineered for high-production panel sizing operations. Featuring a Triple Chip Grind (TCG) tooth geometry and a 72-tooth configuration, this blade is purpose-built for sizing single sheets and multiple panels on large panel sizing machines, delivering clean, chip-free results in melamine, double-sided laminate, chipboard, and MDF. The 4.4mm kerf and 3.2mm plate provide the structural rigidity needed for consistent, accurate cuts in demanding industrial environments.

Key Features

• Triple Chip Grind (TCG) Tooth Geometry - each tooth alternates between a flat top and a chamfered corner, producing clean, chip-free edges in brittle or laminated panel materials where tear-out must be eliminated.
• 72-Tooth Configuration - the high tooth count distributes cutting load across more contact points, resulting in smoother surface finishes on melamine and double-sided laminate panels with minimal post-processing required.
• 430mm Blade Diameter - sized to match the cutting depth requirements of industrial panel sizing machines, enabling full-depth cuts through thick composite panels in a single pass.
• 80mm Bore with COMBI5 Pin Hole Pattern - the COMBI5 arbor configuration ensures precise, secure seating on compatible panel sizing machine spindles, reducing runout and maintaining cut accuracy at production speeds.
• 4.4mm Kerf Thickness - the wide kerf provides blade stability during heavy-duty panel sizing cuts, reducing deflection and maintaining straight, square cut lines across large sheet dimensions.
• 3.2mm Plate Thickness - a rigid steel plate minimizes vibration and lateral flex during cutting, contributing to dimensional accuracy and longer blade service life under continuous industrial use.
• 16 deg. Cutting Angle - the positive hook angle promotes efficient chip evacuation and smooth feed through stacked or single sheet panels, reducing strain on the drive motor.
• Tungsten Carbide (HW) Tip Material - hard metal carbide tips maintain sharp cutting edges through extended production runs, resisting the abrasive wear associated with MDF, chipboard, and laminated materials.

Why This Product

• Engineered for industrial panel sizing machines - the COMBI5 pin hole pattern and 80mm bore diameter are specific to the arbor configurations found on dedicated panel sizing equipment, so the blade mounts securely and runs true without adaptation hardware.
• TCG geometry targets the most demanding laminated panels - materials like melamine and double-sided laminate are notoriously prone to chipping along cut edges. The Triple Chip Grind tooth form is specifically designed to shear these surfaces cleanly, reducing reject rates in high-volume panel production.
• 72 teeth across a 430mm diameter means fine pitch spacing - more teeth per unit of circumference means each tooth removes a smaller chip, which directly translates to smoother cut surfaces on finished panels without requiring secondary edge treatment.
• Tungsten carbide tips stand up to abrasive sheet materials - MDF and chipboard contain resins and mineral particles that quickly dull standard steel teeth. The HW (hard metal) carbide tips resist this abrasion, supporting longer intervals between sharpenings in continuous production environments.

Frequently Asked Questions

What type of machines is this blade compatible with?

This blade is designed for panel sizing machines. The 80mm bore diameter and COMBI5 pin hole pattern correspond to the spindle and arbor configurations found on dedicated industrial panel sizing equipment.

Why is a Triple Chip Grind (TCG) the right tooth geometry for panel sizing applications?

TCG geometry alternates between a chamfered corner tooth and a flat-top tooth. This combination is particularly effective on brittle or laminated surfaces such as melamine and double-sided laminate, shearing the material cleanly to prevent edge chipping and surface tear-out that would be unacceptable in finished panel production.

Can this blade cut both single sheets and multiple panels at once?

Yes. According to the product specifications, this blade is suitable for sizing single sheets as well as multiple panels simultaneously, making it well-suited for high-throughput industrial panel sizing operations.

What does the COMBI5 pin hole designation mean for this blade?

COMBI5 refers to a specific combination bore and pin hole configuration used on industrial panel sizing machines. It indicates the blade has both the 80mm center bore and a matched set of pin holes that align with the machine's arbor pins, ensuring the blade is locked securely in position during operation to prevent any rotational slippage.
