PCD Premill Cutters For KDT Edgebanding Machine Φ125xφ30xH65x18T-(3+3)Z-45

Need to replace the pre-milling head on a KDT edge bander without ordering the wrong one? This PCD premill cutter is 125 mm outside diameter, 30 mm bore, 65 mm high, 18 teeth in a (3+3)Z grouping with the Z-45 arrangement, and a PCD cutting edge 0.4–0.7 mm thick on an alloy body. Key hole style 1 is the KDT pattern and style 2 the Nanxing pattern. It squares the panel edge before the band is applied. Other sizes are quoted on request.

A line running MDF or particle board hits the same three things at the pre-mill station: a panel edge that chips or blows out before the band ever gets there, a replacement head that turns up with the wrong bore or the wrong key hole, and an edge too rough for the glue line to hold. Pre-milling is the station that removes all three, and this cutter is the part that does the cutting.

The head is one part in two materials: an alloy body carrying PCD cutting edges 0.4–0.7 mm thick. The size string reads outside diameter, bore, height, teeth — 125 mm outside, 30 mm bore, 65 mm high, 18 teeth — written 125x30xH65x18T. The teeth sit in a (3+3)Z grouping with the Z-45 arrangement, which is how the head is built, not a selector on the order form.

Two key hole styles are listed. Style 1 is the pattern for KDT edge banders and style 2 the pattern for Nanxing machines, so the head is chosen against the spindle it mounts on rather than against a model name. Customization is supported and other sizes are quoted on request.

Price is on request, quoted against the size and the key hole style you actually need. Send the size string and a photo of the head coming off before the order is fixed.

The cutter described the way a buyer checks it — size, teeth, edge material, then fit:

• PCD on an alloy body. The cutting edges are PCD 0.4–0.7 mm thick, carried on an alloy body, so the wear surface and the structure are two different materials.
• 125 mm cutting circle. 125 mm outside diameter is the first number in the size string 125x30xH65x18T.
• 30 mm bore. The head mounts on a 30 mm spindle; the key hole cut into that bore is what separates the KDT pattern from the Nanxing pattern.
• 65 mm height. 65 mm between the two faces of the head — the third number in the string, after the 125 mm and the 30 mm.
• 18 teeth, (3+3)Z grouping. 18 teeth in a (3+3)Z layout with the Z-45 arrangement, which is the tooth count and grouping this head is built to, not an option.
• Key hole style 1 and 2. Style 1 for KDT edge banders, style 2 for Nanxing machines — both listed against the same head, chosen by the spindle.
• Pre-milling, not trimming. It squares the panel edge before the band is applied; the trimming cutters work on the band afterwards. One station, one job.
• Customization supported. Other sizes and configurations are quoted on request, so the order is placed against the string 125x30xH65x18T-(3+3)Z-45 or against the dimensions you send.

The choice on a dull or chipped pre-mill head is usually to keep running and accept the blown-out edge, or to stop the line and wait for a part nobody can identify. What this head gives you instead:

• Fit settled before the order. The head is picked on 125 mm outside, 30 mm bore, 65 mm height and key hole style 1 or 2, so the match is checked against numbers on the old head.
• One head, one station. Pre-milling is a single station in the line and this is the part that does it, so the fix is one head change rather than a service call.
• Diamond edge at 0.4–0.7 mm. The cutting edges are PCD, 0.4–0.7 mm thick on the alloy body, and the thickness is stated so a reorder is not quietly a different grade.
• 18 teeth sharing the cut. 18 teeth in a (3+3)Z grouping with the Z-45 arrangement spread the cut across the head, which is the layout it was built to.
• A square edge for the glue line. The pre-mill cut is what the banding glue bonds to, so a square edge at 125 mm cutting circle is the difference between a joint that holds and one that fuzzes.
• Sizes beyond the list. Customization is supported, so a machine outside the standard listing gets a quote on request instead of a dead end.

Yes, if the three numbers and the key hole style match the head you are taking off. The head is 125 mm outside diameter with a 30 mm bore and 65 mm height, and it is listed in key hole style 1 for KDT machines. Measure the old head and send a photo of its bore before ordering.

They are outside diameter, bore, height and teeth. So 125 mm across the cutting circle, 30 mm bore, 65 mm high, 18 teeth, written 18T — and (3+3)Z-45 is the tooth grouping and arrangement the head is built to.

Style 1 for a KDT edge bander, style 2 for a Nanxing machine. Both are listed on the same head, so the choice follows the spindle the head mounts on; matching the bore pattern is what stops a correct-looking head from being the wrong part.

It cuts the panel edge before the band is applied; trimming cutters work on the band afterwards. Pre-milling squares and smooths the edge so the glue line has a face to bond to, which is why a dull pre-mill head shows up as a band that lifts.

Because that is the range the PCD layer on this head falls in. The figure describes the diamond cutting layer on top of the alloy body, so it tells you what is cutting — not the overall size of the head.

Yes. Pre-milling runs on the panel edge, and MDF, particle board and plywood are all cut at that station; what changes between them is how fast the edge dulls, not which head is needed.

Yes — customization is supported. Sizes other than 125x30xH65x18T-(3+3)Z-45 are quoted on request, so send the dimensions you need and the key hole style and the answer comes back as a quote rather than a no.

Price is on request, quoted against the size and key hole style you need. Send the size string, the key hole style (1 or 2) and a photo of the head being replaced, and that is enough to quote and to confirm the fit.
