CMT Industrial Panel Sizing Saw Blade - 450mm Diameter, 72-Tooth TCG is a heavy-duty circular saw blade engineered for industrial panel sizing machines. Designed to size single sheets and multiple panels in demanding production environments, this 450mm blade features a Triple Chip Grind (TCG) tooth geometry and a 60mm bore with COMBI7 pin hole pattern, making it a precision fit for industrial panel processing equipment. The 72-tooth configuration and 16 deg. cutting angle deliver clean, controlled cuts through panel materials at up to 4,200 RPM.

Key Features

• Triple Chip Grind (TCG) Tooth Geometry - the alternating flat and chamfered tooth profile reduces chipping at cut edges, producing cleaner results when sizing laminate panels and composite sheet goods.
• 72-Tooth Count on a 450mm Blade - a high tooth count relative to blade diameter means more cutting edges in contact with the material per revolution, supporting smooth surface finish on panel faces.
• 16 deg. Cutting Angle - a positive hook angle promotes efficient chip evacuation and forward cutting action, helping maintain consistent feed rates on industrial sizing machines.
• 4,200 Maximum RPM Rating - matched to the spindle speeds of industrial panel sizing equipment, ensuring the blade operates safely within the design parameters of the machine.
• 60mm Bore with COMBI7 Pin Hole Pattern - the COMBI7 arbor configuration aligns precisely with standard industrial panel sizing machine spindles, eliminating runout caused by adapter rings or mismatched bore fittings.
• 4.8mm Kerf / 3.5mm Plate - the kerf-to-plate ratio provides lateral stability during the cut while minimizing material waste per pass on high-value panel stock.
• Tungsten Carbide (HW) Tips - hard metal carbide tooth tips retain a sharp cutting edge longer than standard steel, reducing the frequency of blade changes in continuous production runs.

Why This Product

• Configured specifically for industrial panel sizing machines with a 60mm bore and COMBI7 pin hole, this blade mounts without modification or adapters on compatible equipment - saving setup time and eliminating concentricity issues.
• The TCG tooth grind is the preferred geometry for sizing panels where edge quality on both the top and bottom face matters, making this blade appropriate for applications involving single sheets and stacked multiple panels.
• At 450mm in diameter with 72 teeth, this blade occupies a working range suited to large-format panel sizing cuts that require both depth capacity and finish quality in the same pass.
• Tungsten carbide (HW) tooth material means the cutting edges hold up in the abrasive conditions of repetitive industrial panel processing, reducing downtime compared to blades with softer tooth materials.

Frequently Asked Questions

What type of machine is this blade designed for?

This blade is designed for industrial panel sizing machines. The 60mm bore and COMBI7 pin hole pattern are standard mounting specifications for that class of industrial equipment.

Why is a Triple Chip Grind (TCG) used on a panel sizing blade?

The TCG geometry alternates between a flat raker tooth and a chamfered chip tooth. This sequence pre-scores and clears material progressively, which reduces edge breakout on panel surfaces - a key quality consideration when sizing laminated or composite sheet goods.

What does the COMBI7 pin hole designation mean?

COMBI7 refers to a specific pin hole pattern on the blade's bore face that corresponds to a standard arbor configuration used on industrial panel sizing machines. It allows the blade to be positively located on the spindle for accurate, repeatable positioning without relying solely on bore friction.

What is the maximum safe operating speed for this blade?

The maximum rated speed is 4,200 RPM. Always verify that the panel sizing machine's spindle speed does not exceed this value before mounting and operating the blade.
