PCD Premilling Cutters 125x30xH65x18T-(3+3)Z-45 KDT Cutting Tools

Yes, if your KDT edgebander takes a φ125 mm disc on a φ30 mm bore at 65 mm height. This 18T PCD premill cutter is that size. Polycrystalline diamond edges 0.4–0.7 mm thick sit on an alloy body; 18 teeth run the 125 mm cut in a (3+3)Z grouping, and the keyhole is style 1, the KDT pattern. Pre-milling squares the panel edge before the banding goes on, so the band adheres to cut fibre instead of bridging a torn edge. Custom sizes on request.

Three things go wrong at the pre-milling station, and none of them stops the machine. The panel edge reaches the glue pot torn instead of square. The banding bridges that torn fibre and lifts a few weeks later. The operator ends up sanding edges by hand at the end of the line while the cutter keeps spinning. A cutter with the wrong keyhole is worse: it will not seat on the spindle at all.

This is a PCD premill cutter for KDT edgebanding machines — polycrystalline diamond on an alloy body, catalogued as a diamond premilling cutter. The size string is φ125 x φ30 x H65 x 18T-(3+3)Z-45: outer diameter 125 mm, inner bore 30 mm, height 65 mm, 18 teeth in a 3+3 grouping.

The diamond layer measures 0.4–0.7 mm, and that layer does the cutting: PCD holds an edge on abrasive board and laminate while the alloy body carries it. 18 teeth share the 125 mm circumference, so each tooth takes a shallow bite per revolution instead of one heavy pass.

It mounts at the pre-milling position and cuts the edge before the banding is applied, so the band bonds across its full width. Keyhole style 1 is the KDT pattern; style 2 is the Nanxing pattern. Origin China, customization supported, other sizes quoted on request.

What decides whether a premill 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. The inner diameter is 30 mm; another arbor size needs another cutter, not a shim.
• 65 mm height. H65 in the size string is the height, so 125 / 30 / 65 mm settles fitment before an order.
• 18 teeth, (3+3)Z. 18T runs around the 125 mm disc, and the size string carries the 45 suffix after the Z.
• PCD layer 0.4–0.7 mm. Polycrystalline diamond on an alloy body — the diamond is the cutting edge.
• Keyhole style 1, KDT pattern. Style 2 is the Nanxing pattern; a KDT spindle needs style 1 to seat.
• Pre-milling, not trimming. It cuts the panel edge before the banding goes on; trimming cutters run after.
• Listed for KDT edgebanders. Catalogued as a premill cutter for KDT edgebanding machines.
• Customization supported. Other sizes are quoted on request rather than confined to one list.
• One line to reorder. φ125 x φ30 x H65 x 18T-(3+3)Z-45 identifies the cutter completely.

When a premill cutter dulls, the choice is usually a cheaper cutter of unknown size, a torn edge running past the banding station, or waiting on a supplier. What this one changes:

• Fitment is settled on paper. φ125 outer, φ30 bore, 65 mm height and keyhole style 1 either match your spindle or do not.
• The banding lands on cut fibre. Pre-milling removes the torn edge the glue would otherwise bridge, which is what keeps a seam flat.
• Diamond does the cutting. A 0.4–0.7 mm PCD layer on an alloy body, so the hard material sits where the chip forms.
• Eighteen teeth share the load. 18T over 125 mm means shallow bites per tooth instead of one heavy pass.
• A reorder is one line. 18T plus the full size string identifies the cutter, so the second order is a copy of the first, not a new drawing.
• Sizes beyond the list. Customization is supported, so a non-standard diameter or height is quoted on request.
• The price follows your quantity. Quoted on request rather than listed, so the figure matches the quantity you actually order, not a single-piece list figure.

Yes, if your spindle takes a φ125 mm cutter on a φ30 mm bore at 65 mm height. That is the size this premill cutter is made to, with keyhole style 1 — the KDT pattern.

φ125 x φ30 x H65 x 18T-(3+3)Z-45. Outer diameter 125 mm, inner bore 30 mm, height 65 mm, 18 teeth in a 3+3 grouping.

18 teeth on the disc. T is the tooth count in tooling sizes, and the 18 teeth sit around a 125 mm circumference in a (3+3)Z grouping.

0.4–0.7 mm. The PCD layer is what cuts; the alloy body behind it carries the cutter.

No. Style 1 is the KDT pattern and style 2 is the Nanxing pattern; the wrong one will not seat on the spindle.

Premill. It cuts the panel edge before the banding is applied; fine trimming and end trimming cutters run after the band is on.

Yes. Customization is supported, and other sizes are quoted on request rather than published as a fixed list.
