PCD 450 x 4.2/3.5 x 30 x 120T Circular Saw Blade for Beam Saws — catalogue designation PCD450*4.2/3.5*30*120T. Dimensions are outer diameter 450 mm with a 4.2 mm kerf and 3.5 mm plate, 30 mm bore and 120T cutting edges in TP (trapezoidal-flat) geometry.
PCD circular saw blade 450 x 4.2/3.5 x 30 mm, 120 teeth. A large-diameter production blade for beam saws cutting stacked panels, where tip life decides how often the line stops.
Applications
Cutting: Large-diameter panel sizing on horizontal beam saws, cutting stacked melamine and MDF panels.
Why this specification
The combination of 450 mm diameter and 120T teeth sets the chip load per tooth at a given feed rate. The 4.2 mm kerf and 3.5 mm plate are chosen together: a thinner plate saves material but reduces how much tension the body can carry, so the plate thickness on this size is set as the practical minimum for stable running at production speed.
The tips are PCD (polycrystalline diamond). Diamond tips hold an edge through abrasive panel materials far longer than carbide, which is what makes a blade at this price point economic on a machine that runs all week.

Ordering notes
Bore size and pin holes must match the machine arbor, and the maximum speed marked on the blade must not be exceeded. If you are replacing an existing blade, the simplest order reference is the marking stamped on the old blade plus the machine make and model.
Diameter and tooth count set the cut; kerf and plate decide how much material and spindle power it costs.

Frequently asked questions
Will a 450 mm blade with a 30 mm bore fit my saw?
The arbor of a 450 mm blade has to match in two places: the 30 mm bore and the pin-hole pattern. Check both against the machine before ordering — the bore is easy to measure, and the pin holes are where machines of the same brand often differ. If your arbor is different, this tooth geometry is built in other bores and pin configurations to order, so the specification is moved to your machine rather than the other way round.
120T on a 450 mm blade — what does that limit?
Tooth count sets the chip load per tooth at a given feed rate. 120T on a 450 mm blade is a fine-finish count for trimming and cross-cutting, where surface quality matters more than feed rate. A higher count leaves a cleaner edge and a slower practical feed; a lower one cuts faster and leaves a rougher edge. The geometry on this blade is TP (trapezoidal-flat).
Can the bore, kerf or tooth count be changed?
Yes. Diameter, kerf, plate thickness, bore, pin holes and tooth count are all made to the machine and to the material being cut. When replacing a worn blade, the fastest route is a photograph of the marking stamped on the old blade plus the machine make and model — the quotation is then built on that specification rather than on the nearest stock size.
Why PCD rather than carbide here?
PCD holds its edge through abrasive material far longer than carbide, which is why it is specified for large-diameter panel sizing on horizontal beam saws, cutting stacked melamine and MDF panels. It costs more per blade and is the cheaper option per cut wherever the material is abrasive enough to wear a carbide edge out quickly. On clean softwood or short runs, carbide stays the more economical choice.
What should I quote when I inquire?
PCD450*4.2/3.5*30*120T, plus the quantity and the machine make and model. Those three are enough to confirm the specification, the minimum quantity for the size and the production lead time in the quotation.
