4014030144 4014030143 Carbide Inserts 12x14.5x2 Scraper Knives For Homag

Need to replace the scraper knives on a Homag edgebander without waiting on a local grind? 4014030144 and 4014030143 are the same carbide insert: 12 x 14.5 x 2 mm, R3 radius, 4 mm bore, offered in both L and R hand. They are packed 10 pcs per box with an MOQ of 10 pcs, so one box refills one scraper station. If your holder clamps a 2 mm insert on a 4 mm pin, this is the replacement to order.

An edgebander that stops at the scraper station is usually stopped by one of three things: an insert that chips on the first shift, a radius that does not match the relief on the panel edge, or a spare that arrives as the wrong hand. The 4014030144 and 4014030143 inserts are built for that station only, and each of those three failures is answered by a fixed dimension rather than by a claim.

Both numbers describe the same insert: a tungsten carbide (TCT) scraper knife measuring 12 x 14.5 x 2 mm, with an R3 scraping radius, a 4 mm bore, and a cutting edge listed in both L and R hand. It is a replacement for the Homag scraper station, so the fit is decided by those four numbers and nothing else.

Carbide is what holds the R3 geometry. The edge scrapes cured glue and edge overhang off the panel instead of slicing through timber, so a steel blade tends to round off its radius early while a TCT insert keeps the profile it was ground to. That is the whole reason the scraper station is specified in carbide.

Packing is 10 pcs per box and the MOQ is 10 pcs, so a single box is a single station refill. Origin: China.

These dimensions and packing facts decide whether this insert fits your scraper station.

• Two part numbers, one insert — Homag 4014030144 and 4014030143 are the same 12 x 14.5 x 2 mm scraper knife, so both order lines take one box.
• 12 x 14.5 x 2 mm body — 12 mm width, 14.5 mm length, 2 mm thickness: the scraper seat dimensions, not a size to be ground down.
• R3 scraping radius — the edge carries a 3 mm radius, the profile the scraper station is set up for, not a square corner.
• 4 mm bore — the hole measures 4 mm, so the insert goes onto the existing holder pin without re-drilling.
• L and R hand — both cutting directions are listed, so left and right scraper seats are re-bladed from one box.
• Tungsten carbide (TCT) — the body is carbide, which is how an R3 edge survives scraping cured glue rather than cutting timber.
• 10 pcs per box — counted by the piece, so a box is a known number of replacements rather than a weight.
• Homag scraper station fit — offered as a replacement insert for Homag edgebanders, clamped at the 2 mm thickness of the scraper holder.
• Reorder by number — both part numbers are on the page, so the next order is a number lookup, not a photo and a caliper.

Buying a scraper insert usually comes down to ordering the original number or having something ground locally to fit. Both cost time, and only one of them keeps the R3 profile repeatable.

• Both hands from one line item. Order 4014030144 and 4014030143 together and the left and right scraper seats are covered without a second supplier or a second minimum.
• No holder work at changeover. A 4 mm bore and 2 mm thickness mean the insert goes straight onto the pin the old one came off — no reaming, no shimming, no hand grinding.
• The edge profile is fixed, not estimated. Every insert is ground to R3, so the finish at the panel edge does not drift with whichever operator set the machine that morning.
• Small first order. MOQ is 10 pcs, which is one box and one station refill, so a new line can be trialled before it is stocked.
• Countable stock. At 10 pieces per box the drawer can be counted against output instead of guessed, and a reorder is triggered by an empty box rather than a bad edge.
• A number you can reorder. The two part numbers stay with the product page, so the next purchase does not depend on a sample, a photo or a measurement taken off a used blade.

Yes, if your scraper station takes the 12 x 14.5 x 2 mm insert. Both numbers are listed against the same dimensions — 12 mm width, 14.5 mm length, 2 mm thickness — so ordering either one delivers the same scraper knife.

They are the three body dimensions in millimetres. 12 mm is the width, 14.5 mm is the length and 2 mm is the thickness; the R3 that follows is the edge radius, not a fourth dimension.

Yes. R3 is shorthand for a 3 mm radius on the cutting edge. The R stands for radius; the cutting hand (L or R) is a separate line on the specification.

No, both are listed for this insert. It is offered in L and R cutting directions and packed 10 pcs per box, so say which seat you are filling when you send the order.

4 mm. The mounting hole is 4 mm, and that is the dimension that decides whether the insert seats flat on your holder pin rather than riding on it.

10 pcs per box, and the MOQ is 10 pcs — one box. There is no need to buy a full carton to test a single scraper station.

Carbide. The insert is tungsten carbide (TCT), which is why an R3 edge can scrape cured glue off the panel without rounding off the way a steel blade does.

Only if your holder matches the four dimensions. This insert is a replacement for the Homag scraper station and is defined by 12 x 14.5 x 2 mm, R3, 4 mm bore and L/R hand — if your holder clamps a 2 mm insert on a 4 mm pin, the fit is a dimensions question, not a brand question.
