φ125Xφ30XH40（3+3）9T PCD Pre Milling Cutter For KDT Edgebander Trimming Tools

If your KDT edgebander takes a φ125 mm disc on a 30 mm bore at 40 mm height with 1 key groove, this 9T PCD pre-milling cutter is that size. It is supplied as a pair — 2 pcs, 4.95 kg — and it squares the panel edge before the banding goes on, so the glue meets cut fibre rather than torn fibre. The size string is φ125Xφ30XH40 (3+3) 9T, part number PMC302. The same 125x30x40 size is also available with 2 key grooves for Nanxing machines.

Three costs hide at the pre-milling station of an edgebanding line. A torn panel edge reaches the glue pot, the banding bridges that torn fibre, and the seam lifts weeks later at the customer's site. Operators then sand the edges by hand while the line keeps running. A cutter with the wrong key groove adds a fourth cost: it will not seat on the spindle at all.

This is a PCD pre-milling cutter for KDT edgebanding machines — polycrystalline diamond on a steel disc, catalogued as a woodworking machinery tool. The size string is φ125Xφ30XH40 (3+3) 9T: outer diameter 125 mm, inner bore 30 mm, height 40 mm, 9 teeth.

It mounts at the pre-milling position and cuts the edge before the band is applied. The central hole carries 1 key groove, the KDT pattern; the same size ships with 2 key grooves for Nanxing machines. Every set is a pair: 2 pcs, 4.95 kg net.

Price is quoted per order, and customization is supported, so a diameter or height outside this list is quoted from your drawing. Cutters travel wrapped in a cardboard box.

What decides whether a pre-milling cutter squares the edge or only rubs it:

• 125 mm outer diameter. The disc measures 125 mm across, the size the KDT pre-milling station is listed to take.
• 30 mm bore, 1 key groove. Inner diameter 30 mm with a single keyway; the 2-keyway version is for Nanxing spindles.
• 40 mm height. H40 in the size string is the height, so 125 / 30 / 40 mm settles fitment before an order.
• 9T in a (3+3) grouping. 9 teeth run around the 125 mm disc, written as (3+3) in the size string.
• PCD cutting edges. Polycrystalline diamond sits on the tooth, so the wear-resistant material is where the chip forms.
• Pair supply, 2 pcs. One order is 1 pair at 4.95 kg, so both cutters on a station arrive matched.
• Pre-milling, not trimming. It cuts the panel edge before glue and banding; fine trimming cutters run after.
• Listed for KDT machines. Catalogued as a pre-milling cutter for KDT edgebanding machines.
• Customization supported. Non-standard diameters and heights are quoted on request.
• Packed for transit. A cardboard box with the cutters wrapped, so 2 pcs arrive without edge chipping.
• One line to reorder. PMC302 plus φ125Xφ30XH40 (3+3) 9T identifies the cutter completely.

When a pre-milling cutter dulls, the choice is usually a cheaper disc of unconfirmed size, a torn edge running on to the glue pot, or a line stopped while a replacement is sourced. What this cutter changes:

• Fitment is settled on paper. φ125 outer, φ30 bore, 40 mm height and 1 key groove either match your spindle or do not — before any money moves.
• The banding lands on cut fibre. Pre-milling squares the edge the glue would otherwise bridge, which is what keeps a seam flat months later.
• Diamond sits where the chip forms. PCD edges on a 125 mm disc, so the hard material is at the cutting point instead of deeper in the body.
• Nine teeth, shallow bites. 9 teeth share the 125 mm circumference, so each tooth takes a light cut per revolution.
• Both cutters arrive matched. A pair is 2 pcs at 4.95 kg, shipped together, so a station is never running one new cutter against one worn cutter.
• A reorder is one line. PMC302 or the string φ125Xφ30XH40 (3+3) 9T re-orders the same cutter instead of a new drawing.
• Nanxing machines stay covered. The 2-key-groove version of the same 125x30x40 size is quoted on request.
• The price follows your quantity. Quoted per order rather than listed, so the figure matches the quantity you actually buy.

Yes, if your spindle takes a φ125 mm disc on a 30 mm bore at 40 mm height with 1 key groove. That is exactly the size and keyway this cutter is made to.

φ125Xφ30XH40 (3+3) 9T. Outer diameter 125 mm, inner diameter 30 mm, height 40 mm, 9 teeth, part number PMC302.

Two. One order is 1 pair = 2 pcs, with a net weight of 4.95 kg per pair.

No. 1 key groove is the KDT pattern; the same 125x30x40 size is available with 2 key grooves for Nanxing edgebanders.

Pre-milling. It cuts the panel edge before the banding is applied, while fine trimming and end trimming cutters run after the band is on.

It is the published notation for this cutter: 9 teeth, written in a (3+3) grouping. We quote the string as published rather than re-interpreting it.
