75x20xH16x4Z Cutting Milling Tools Fine Trimming Cutters Woodworking Machinery Tool

Need to replace a fine trimming cutter without ordering the wrong bore? The EC105 TCT fine trimming cutter is 75 mm outside diameter, 20 mm bore, 16 mm height and 4 teeth, listed as 75x20xH16 4Z, with R1.5, R2 and R3 edge radius all available, so the profile is chosen from a part number instead of guessed from a photo. Cutting edge is tungsten carbide, each cutter is individually packed, and custom sizes are produced on request. Three numbers decide fitment: 75 mm outer diameter, 20 mm bore, 16 mm height.

A trimmer station loses time in three familiar places: a cutter ordered from a photograph that arrives with the wrong bore, a profile that has to be re-cut because the last spare did not match the radius, and a small part that holds the line while on order. The EC105 is listed to answer those three, one dimension at a time.

It is a 75 mm diameter tungsten carbide tipped fine trimming cutter with a 20 mm bore, a 16 mm height and 4 teeth, written 75x20xH16 4Z. Four teeth on a 75 mm circle make it a finishing cutter for the edge banding station: it takes the excess banding material off the panel edge rather than hogging it away, with the teeth arranged to keep chip load and heat low.

Edge radius is listed as R1.5, R2 or R3, all available, so the profile running on the machine is matched by part number instead of reground from a sample. The cutting edge is TCT tungsten carbide, the grade that carries the wear through continuous edge banding work.

Custom cutters are supported: send a drawing, or the three dimensions plus the radius, and the cutter is produced to that request. Each cutter is individually packed, and price is quoted against the quantity asked for.

What 75 mm, a 20 mm bore and four teeth decide:

• 75 mm cutting circle — the outer diameter is 75 mm, which fixes how far the cutter reaches across the banded edge and where it sits in the head.
• 20 mm bore, stated not assumed — the inner diameter is 20 mm, the number that has to match the machine before anything else is checked.
• Four teeth on a 75 mm circle — 4 teeth, written 4Z in the size string, take the finishing pass over the edge banding material instead of bulk removal.
• Three radii, one body — R1.5, R2 and R3 are all available on the same 75x20xH16 4Z cutter, so one family covers three edge profiles without a second part number series.
• TCT tungsten carbide edge — the cutting edge is tungsten carbide, placed exactly where the cut happens, which is the part that wears.
• Tooth form controls chip load — the four teeth are ground to remove material efficiently at low chip load, which also limits heat at the cutting edge.
• Edge banding application — listed as a cutting tool for woodworking edge banding machines, trimming excess banding material at the trimmer station.
• Custom sizes to request — customisation is supported, so a different diameter, height, tooth count or radius is produced against a drawing.

For a shop ordering a trimmer from a photograph, or paying an outside service to regrind a worn profile:

• Change the cutter, keep the head. The trimmer head, its setting and its clamping stay on the machine; only the 75 x 20 x 16 mm cutter is replaced.
• The bore is on the page, not in an email. 20 mm inner diameter is published, so a worn bore is matched before the order, not after the line has stopped.
• One body, three radii. R1.5, R2 and R3 come from the same 75x20xH16 4Z cutter, so a profile change is a part number change, not a search for a new cutter family.
• Four teeth take the last cut. 4 teeth on a 75 mm circle finish the overhang, and that finishing cut is what the customer sees on the finished panel edge.
• A wear part in the drawer. At 75 mm diameter the cutter is a consumable, so one spare on the shelf turns a line stop into a change at the head.
• Custom is a request, not a project. Customisation is supported, so a non-standard radius on a standard body arrives as one line item with the order.
• Price follows the quantity. Quotes are given against the quantity asked for, so a stock order and a single spare are priced separately.

Check the 20 mm bore first — that is the fit. The cutter is listed as a cutting tool for woodworking edge banding machines generally rather than for one machine badge, so bore, outside diameter and height are what decide fitment: confirm 20 mm, 75 mm and 16 mm against the trimming head on your machine.

It is the size string of the cutter, read left to right. 75 is the 75 mm outer diameter, 20 is the 20 mm inner diameter or bore, H16 is the 16 mm height, and 4Z is four teeth. Every number on the cutter is accounted for by that string.

Order the radius that is already on your machine. R1.5, R2 and R3 are all available on the same 75x20xH16 4Z cutter, so the radius you name is the radius that ships; read it off the worn cutter or the machine setting rather than measuring a photo.

Both mean the same thing — 4Z is four teeth. The listing states 4 teeth in the specification and writes 4Z in the size string, so the number appears twice and is not taken from the product name alone.

Tungsten carbide, TCT — tungsten carbide tipped. The carbide sits at the cutting edge, which is the part that wears on edge banding work, while the body carries the 20 mm bore and the 4Z tooth pattern.

Yes — customisation is supported. A cutter outside the standard 75x20xH16 4Z size, or with a radius other than R1.5 / R2 / R3, is produced against a drawing; send the dimensions or the drawing and it is quoted as a custom item.

One cutter per pack, individually packed. The listing quotes on request instead of at a fixed figure, so send the model EC105, the radius and the quantity, and the price comes back against that quantity.

Four numbers: the 75 mm outer diameter, the 20 mm bore, the 16 mm height and the radius stamped on the old cutter. Measure a worn cutter with a caliper across all four, because a match on three of them is still a part that will not seat.
