CMT Industrial Panel Sizing Saw Blade - 420 x 80mm, 72-Tooth TCG is a heavy-duty circular saw blade engineered by CMT for industrial panel sizing machines handling single sheets and multiple panel stacks. With a Triple Chip Grind (TCG) tooth geometry, 72 teeth, and a 420mm diameter, this blade is purpose-built for the clean, precise sizing cuts demanded in high-volume panel processing operations. Whether you are cutting large chipboard sheets, MDF panels, or laminated boards, the TCG grind delivers smooth edges and chip-free results that keep production lines running efficiently.

Key Features

• Triple Chip Grind (TCG) Tooth Geometry - alternating flat and chamfered teeth produce clean, splinter-free cuts in panel materials, reducing secondary finishing work and improving throughput on panel sizing lines.
• 72 Teeth at 420mm Diameter - a high tooth count relative to blade size means more cutting edges engage the material per revolution, resulting in smoother cut surfaces and finer edge quality on single sheets and stacked panels.
• 15 deg. Cutting Angle - the positive hook angle provides efficient chip clearing and forward feed action, keeping the blade running smoothly under the continuous feed conditions typical of industrial panel sizing machines.
• 4.4mm Kerf with 3.2mm Plate - the 4.4mm tooth thickness over a 3.2mm plate provides adequate clearance to prevent blade binding during cuts through dense composite panels while minimizing material waste.
• 80mm Bore Diameter with Multi-Pattern Pin Hole Configuration (4/9/100 + 2/9/110 + 2/14/110) - the large-format metric bore and multi-position pin hole pattern are compatible with a wide range of industrial panel sizing machine arbors, simplifying fitment across different machine platforms.
• Hard Metal (HW) Carbide Tipped Construction - tungsten carbide tips withstand the abrasive demands of repeated sizing cuts through engineered wood products, extending blade service life compared to standard steel-tooth designs.

Why This Product

• Designed specifically for panel sizing machines, this 420mm TCG blade addresses the core requirement of industrial flat-panel production - clean, repeatable cuts through single sheets and multiple panels in a single pass, reducing scrap and rework.
• The 72-tooth TCG geometry is matched to the demands of abrasive composite materials commonly processed on panel sizing lines, where standard ATB grinds wear prematurely and leave torn edges.
• The multi-pattern pin hole layout (4/9/100 + 2/9/110 + 2/14/110) paired with an 80mm bore provides broad machine compatibility, making this a versatile replacement blade across different industrial panel sizing machine configurations.
• Hard metal (HW) carbide construction supports the extended run times and high feed rates of continuous production environments, helping shops maintain consistent cut quality over long blade life cycles.

Frequently Asked Questions

What type of machines is this blade designed for?

This blade is designed for panel sizing machines. The 420mm diameter, 80mm bore, and multi-pattern pin hole configuration (4/9/100 + 2/9/110 + 2/14/110) are all sized to suit the arbor specifications common to industrial panel sizing equipment.

What does the TCG tooth grind do, and why is it used for panel sizing?

TCG stands for Triple Chip Grind, a tooth geometry that alternates between flat-top teeth and chamfered teeth. This pattern is specifically effective for sizing engineered wood panels because it produces clean, chip-free edges on both faces of the cut material, which is critical when working with laminated or composite panels where surface quality matters.

What do the pin hole specifications mean for machine compatibility?

The pin hole designation 4/9/100 + 2/9/110 + 2/14/110 describes the quantity, diameter, and bolt-circle diameter of the locating pins on the blade flange. This multi-pattern configuration allows the blade to fit multiple industrial panel sizing machine arbor configurations, giving it broad compatibility across different machine makes without requiring adapters.

What is the difference between the kerf thickness and the plate thickness on this blade?

The kerf thickness (4.4mm) is the total width of the cut made by the carbide teeth, while the plate thickness (3.2mm) is the thickness of the steel body of the blade. The difference between these two measurements - 1.2mm per side - provides the clearance that prevents the body of the blade from rubbing against the cut walls, which is important for smooth, binding-free operation in dense panel materials.
