φ125Xφ30XH43 PCD Pre Milling Cutter Double Keyway Diamond Milling Cutter

Replacing a pre-milling head on a KDT edgebander? The PMC303 fits on three numbers: φ125 mm outer diameter, φ30 mm bore, H43 mm height, on a double keyway drive. Tips are PCD diamond, so the edge stays square over far more board than carbide. One unit is a matched pair — 2 pcs, 4.1 kg net and 5 kg gross per pair. Measure the spindle, confirm the keyway, and the pair squares melamine, veneer, PVC or ABS edges before the glue pot.

An edgebanding line keeps hitting the same three things: a pre-milling head that tears instead of shears after a few hundred metres, a replacement pair ordered by machine label that arrives with the wrong bore or keyway, and a trim line that appears once the glue has cured. PMC303 is built to remove all three.

It is a PCD pre-milling cutter for edgebanding machines: a matched pair of diamond-tipped heads that squares the panel edge before the glue pot and pressure roller reach it. Size is φ125 * φ30 * H43 mm — 125 mm outer diameter, 30 mm bore, 43 mm cutting height — on a double keyway, so torque is split across two shoulders and the head cannot slip in a full-depth cut. One unit is 2 pcs, 4.1 kg net and 5 kg gross.

The pair suits KDT edgebanders and runs on melamine, veneer, PVC and ABS edges. The tips are polycrystalline diamond rather than carbide, so cutting geometry holds far longer, and the edge leaving the head is square and free of saw ripple — which is what lets the band sit flush without sanding the joint afterwards.

Fit is decided by three numbers, not by the label: 125 mm outer diameter, 30 mm bore, 43 mm height, plus the double keyway. Check them against the spindle and the pair goes on without shimming.

What separates this pair from a generic 125 mm pre-milling head:

• Double keyway drive — torque is shared across two keyways, so the head stays seated on the spindle through a full-depth cut instead of creeping.
• PCD diamond tips — polycrystalline diamond holds its cutting geometry far longer than carbide on abrasive melamine and PVC board.
• 125 mm cutting circle — φ125 mm outer diameter on a 30 mm bore, the pre-milling station size used on KDT edgebanders.
• 43 mm cutting height — 43 mm of cutting height covers board thickness up to 43 mm in one setting, with no second pass.
• Sold as a matched pair — 1 unit = 2 pcs, left and right, so both sides of the edge are cut by heads set to the same size.
• 4.1 kg per pair — 4.1 kg net and 5 kg gross per pair, one pair to a carton, so it can be carried to the head by hand.
• Four edge materials — melamine, veneer, PVC and ABS are all pre-milled by the same pair of cutters.
• Square edge before the glue — the head removes the ripple left by the panel saw, so the band seats flush instead of riding on high spots.
• Protective carton — each pair ships in its own carton box, so the diamond tips do not contact anything else in transit.

The usual choice is between sending a dull head out for regrinding and running it until the trim line shows on the finished panel. A spare pair on the shelf ends that choice.

• No shutdown while a head is away. A second pair in the tool crib turns a waiting week into a changeover of a few minutes.
• Order by three numbers, not by a label. 125 mm outer diameter, 30 mm bore, 43 mm height and double keyway is the whole fit check, with no model-year guessing.
• The keyway is what fails first on a cheap head. Two keyways carry the torque that one keyway would take alone, which is the difference between a head that lasts and one that spins on the spindle.
• Diamond holds the edge, so the band holds the line. A dulled head leaves a rounded edge, and a rounded edge reappears as a shadow line along every panel you ship.
• One SKU covers four edge materials. melamine, veneer, PVC and ABS run on the same pair, so stock is one part number instead of four.
• Weight you can plan around. 4.1 kg net and 5 kg gross per pair — one person, one carton, no lifting gear.

Yes, if the spindle is 30 mm with a double keyway. Outer diameter 125 mm and cutting height 43 mm complete the fit check; measure the spindle before ordering and the pair goes straight on.

φ125 * φ30 * H43 mm — that is 125 mm outer diameter, 30 mm bore and 43 mm cutting height, supplied as one pair of 2 pcs.

A pair — 2 pcs. Both heads ship together, so the left and right sides of the edge are cut by cutters set to the same size.

It drives the head on two shoulders instead of one. On a full-depth cut that keeps the cutter seated on the spindle rather than letting it slip.

Yes. The same pair pre-mills melamine, veneer, PVC and ABS edges.

Diamond holds its cutting geometry far longer on abrasive board. Carbide dulls, the edge rounds over, and the rounded edge shows up as a shadow line along the band.

4.1 kg net and 5 kg gross per pair. Each pair travels in its own protective carton box.

Yes, other sizes are quoted to order. This listing is the 125 mm outer diameter / 30 mm bore / 43 mm height pair; send the spindle drawing for anything else.
