Why this specification
The combination of 305 mm diameter and 140T teeth sets the chip load per tooth at a given feed rate. The 2.8 mm kerf and 2.2 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 TCT (tungsten carbide tipped). Carbide is the right grade where the panel is not aggressively abrasive: it takes and holds a fine edge, and it can be resharpened several times before the tooth geometry is used up. For continuous cutting of highly abrasive board or cement-based sheet, the same blade geometry is built with PCD tips, which hold an edge several times longer in that duty.
Specification
Outer diameter 305 mm | Kerf 2.8 mm | Plate thickness 2.2 mm | Bore 25.4 mm | Teeth 140T | Tooth geometry ATB fine tooth for cross-cutting and trim | Tip material TCT (tungsten carbide tipped).
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 305 mm blade with a 25.4 mm bore fit my saw?
The arbor of a 305 mm blade has to match in two places: the 25.4 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.
140T on a 305 mm blade — what does that limit?
Tooth count sets the chip load per tooth at a given feed rate. 140T on a 305 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 ATB fine tooth for cross-cutting and trim.
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.
What should I quote when I inquire?
TCT305*2.8/2.2*25.4*140T, 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.
