Product Description
CMT Industrial Panel Sizing Saw Blade - 430mm x 75mm Bore, 72-Tooth TCG is a professional-grade circular saw blade engineered specifically for industrial panel sizing machines. Featuring a Triple Chip Grind (TCG) tooth geometry and a 72-tooth configuration, this blade delivers clean, chip-free results when sizing single sheets and multiple panels of melamine, double-sided laminate, chipboard, and MDF. Designed around a 75mm bore with a COMBI pin hole pattern (4/15/105), it integrates directly with standard industrial panel sizing machine arbor configurations for reliable, repeatable performance in demanding production environments.
Key Features
- Triple Chip Grind (TCG) Tooth Geometry - alternating flat and chamfered teeth are optimized for hard, abrasive materials like melamine and laminate, reducing chipping and splintering on both faces of the panel during sizing cuts.
- 72-Tooth Configuration - a high tooth count distributed around the 430mm diameter delivers finer, smoother cuts with less material tearout, making it well-suited for finished panel production where surface quality matters.
- 16 deg. Cutting Angle - a positive hook angle promotes efficient chip evacuation and controlled feed rate, helping maintain consistent cut quality across single sheets and stacked multiple panels.
- 430mm Blade Diameter with 75mm Bore - sized to fit industrial panel sizing machines with 75mm arbor configurations, providing the cutting reach needed for full-width panel sizing operations.
- 4/15/105 COMBI Pin Hole Pattern - the standard industrial COMBI pin hole layout ensures precise blade seating and positive blade location, reducing runout and improving cut accuracy on sizing equipment.
- 4.4mm Kerf Thickness / 3.2mm Plate Thickness - a controlled kerf-to-plate ratio balances cutting stability with material removal efficiency, minimizing waste while maintaining a rigid blade body during heavy panel sizing cycles.
- Tungsten Carbide (HW) Tip Material - hardmetal-tipped teeth resist heat and wear generated during continuous industrial sizing operations, extending edge life between sharpenings.
Why This Product
- Purpose-built for industrial panel sizing - this blade is specifically designed for panel sizing machines, not adapted from a general-purpose design. The 75mm bore, COMBI pin hole pattern, and 430mm diameter address the exact arbor and cutting geometry requirements of industrial sizing equipment.
- TCG geometry handles the most demanding panel materials - sizing double-sided melamine and laminate chipboard demands a tooth form that will not fracture coatings on entry or exit. The Triple Chip Grind geometry is the established solution for these abrasive, brittle-faced materials.
- High tooth count supports production-quality surface finish - with 72 teeth across a 430mm diameter, this blade is configured for a fine finish suitable for panels that go directly to assembly or finished product without additional edge processing.
- Tungsten carbide tips support extended production runs - hardmetal (HW) tipping is the standard for industrial panel sizing applications where blade changes interrupt production. Longer edge retention between resharpening intervals helps maintain throughput.

Frequently Asked Questions
What type of machines is this blade compatible with?
This blade is designed for industrial panel sizing machines with a 75mm arbor bore. The 4/15/105 COMBI pin hole pattern ensures proper blade seating and positive location on equipment that uses the standard COMBI arbor configuration common in industrial panel sizing operations.
Why is TCG (Triple Chip Grind) the right tooth form for panel sizing?
TCG geometry alternates between a flat raker tooth and a chamfered leading tooth. This combination scores and clears material in a controlled sequence, which is particularly effective on hard, brittle-surfaced materials like melamine and double-sided laminate where conventional tooth forms can cause edge chipping or delamination on the panel face.
Can this blade be resharpened?
Yes. The blade is tipped with hardmetal (HW / tungsten carbide), which is a resharpening-capable material. Industrial TCG blades of this class are typically serviced by professional saw sharpening operations that can regrind the carbide tips to restore cutting edge geometry.
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 blade, determined by the set of the carbide tips. The plate thickness (3.2mm) is the thickness of the steel body of the blade itself. The difference between these two dimensions - approximately 1.2mm per side - provides the necessary blade body clearance to prevent binding in the cut during panel sizing operations.
