68x16xH16x6Z TCT Fine Trimming Cutting Blades Woodworking Edgebander Tools

Need a fine trimming blade that takes the last of the overhang off a banded edge without tearing the band? The EC109 is a TCT fine trimming cutting blade listed as 68X16XH16X6Z: 68 mm outside diameter, 16 mm bore, 16 mm height, 6 tungsten carbide teeth, 0.44 kg per pair. Radius is quoted as R1.5, R2 or R3. It is listed for woodworking edge banding machines including KDT and SenBsen, custom blades are quoted from your drawing, and price follows the quantity you ask for.

Three things stop an edge banding line: a fine trimming blade that has lost its radius and now tears the band instead of shearing it, a replacement that arrives with the right diameter but the wrong bore or height, and a wait on an outside shop for one small head. The EC109 lets a shop hold the right blade before it needs it.

It is a TCT fine trimming cutting blade for woodworking edge banding machines: 68 mm outside diameter, 16 mm bore, 16 mm height, 6 teeth, listed as 68X16XH16X6Z. On a 68 mm circle those six teeth sit about 35.6 mm apart along the rim, so each tungsten carbide tooth takes one sixth of the overhang per pass.

The number that most often mismatches is the bore: 16 mm, checked with a caliper on the spindle seat, not read off a worn blade. Height is the H in the callout, also 16 mm, and the listed weight is 0.44 kg per pair, which is 0.22 kg per blade.

Carbide is the wear part. When the radius goes, the blade is changed and the trimmer head keeps its setting; the radius is ordered from the callout on the head — R1.5, R2 or R3. It is listed for machines including KDT and SenBsen, custom blades are quoted from a drawing, and price follows the quantity.

Four numbers, one material and one radius decide what this blade does at the trimmer station:

• 68 mm cutting circle — the outside diameter in the callout, and the rim that decides which trimmer station it sits on.
• Six teeth on that rim — 6 carbide tips roughly 35.6 mm apart around a 68 mm circle, so one pass is shared six ways.
• 16 mm bore — the seat that centres the blade on the spindle; measure it with a caliper before ordering, not by eye.
• 16 mm height (H) — the third number in 68X16XH16X6Z, ordered against the height marked on your trimmer head.
• CT / tungsten carbide — the tooth material named on the listing, which is why the radius is ground into the tooth, not filed at the machine.
• R1.5 / R2 / R3 — three radius callouts under one blade size; the exact one is quoted on request, not assumed from the size line.
• 0.44 kg per pair — weight is listed the way the blade is counted, two pieces to a pair.
• Fine trim, not rough trim — this is the blade that takes the glued overhang back to the panel face after the coarse trim has made its pass.
• KDT and SenBsen fitment — both machine names are on the listing, so the compatibility check starts at the machine plate.

What changes for a shop that has been running a chipped blade to the end of the shift, or sending one head out for regrinding:

• The band comes off clean, not torn. 6 carbide teeth shear the overhang back to the panel face, so the edge does not need a second scraping step.
• No outside run for one small blade. A 0.44 kg pair in the drawer turns a regrinding round trip into a change at the trimmer station.
• Wrong orders drop. 68 mm, 16 mm bore, 16 mm height and 6 teeth all sit in the size name, so the order line carries the whole fitment.
• One blade size, three radii. R1.5, R2 and R3 share the 68X16XH16X6Z body, so one row in the spare list covers three profiles.
• Spend on the wear part only. The blade is replaced; the trimmer head, flange and its setting stay on the machine.
• Fitment answered before the order. KDT and SenBsen are named on the listing, so compatibility is a check on the machine rather than a trial purchase.
• Pairs, not odd pieces. Weight is quoted per pair, so spare stock is counted in matched pairs that go on together.
• A custom radius without a second supplier. A callout outside the three listed is quoted from your drawing, so stock and specials come from one vendor.

It is outside diameter, bore, height and tooth count: 68 mm OD, 16 mm bore, 16 mm height, 6 teeth. The X separates the three measurements, the H marks the height, and the Z is the tooth count.

It fits if your trimmer head takes a 68 mm blade on a 16 mm bore with a 16 mm height. The blade is listed for woodworking edge banding machines including KDT and SenBsen; a match on diameter alone does not confirm the bore, so check the spindle seat first.

Order the radius marked on your trimmer head, not the one that looks closest on a worn blade. The size line lists all three callouts on the same 68X16XH16X6Z body, and the exact one is quoted on request.

Tungsten carbide. The listing gives the material as CT / tungsten carbide, which is why the edge is a ground radius in the tooth tip rather than a filed edge.

No. They are two different measurements that happen to share the number 16 mm. The bore is the hole the spindle passes through, and the height is the cutting body height marked H in 68X16XH16X6Z.

By the pair — the listed weight is 0.44 kg per pair. That is about 0.22 kg per blade, and the two blades of a pair are changed together so both trimmer stations stay on the same radius.

Yes, custom blades are quoted from your drawing. The remarks on the listing say custom cutters are produced to request, so a radius or height outside the three listed sizes starts from your drawing or measured dimensions, not from a size name.

Quoted against the quantity — the listing carries contact-us-for-pricing rather than a fixed figure. Send the model EC109, the radius and the quantity, and the price comes back against that.
