Edgebander Carbide Insert Cutting Knife 12x17x2-R2R Edgebanding Scraping Blades

A dull scraper edge normally means waiting on a part or buying a new scraper unit. The 12x17x2-R2R is only the carbide insert: 17 mm long, 12 mm wide, 2 mm thick, with a 2 mm radius edge, supplied in left-hand and right-hand versions. It bolts into the scraper station your woodworking edgebanding machine already has and takes over the last scrape after trimming, so the glue line comes out clean on melamine, PVC, ABS and veneer edges. Quotation on request.

Three things slow an edgebanding line down. One dull scraper stops a whole station, because every tool family wants its own spare. The worn edge then goes out for honing, and the result depends on who did it. A blade run too long leaves a shiny glue line that no polishing hides. This insert is aimed at all three.

The 12x17x2-R2R is a scraping blade insert knife for woodworking edgebanding machines. It measures 17 mm long, 12 mm wide and 2 mm thick, and the cutting edge carries a 2 mm radius, which is what the R2 in the code means. The R2R suffix marks the item as available in left-hand and right-hand direction, so you order the side your holder carries instead of grinding one.

Nothing gets rebuilt. The old insert leaves the holder, the new one goes in on the same screw, and the station is back in line. That matters on the last pass of the panel, after the trimming cutters. Melamine, PVC, ABS and wood veneer edges all run with the same insert.

Each insert is marked 12X17X2-R2 on the body, so the size is verifiable at the bench. Brand is Shunhongyu. Price is quotation on request; send the hand direction and the quantity you run, and the part is confirmed against your code before it ships.

What the insert is, in numbers you can check:

• Carbide body — the whole insert is carbide, not a brazed tip, so the 2 mm section holds an edge against abrasive glue.
• 2 mm radius edge — ground to a 2 mm radius, the profile that leaves a matching radius on the panel edge.
• 17 x 12 mm footprint — 17 mm long and 12 mm wide, the size a scraper holder is machined to accept.
• 2 mm thickness — a 2 mm body seats flat in the holder slot, so a flipped insert presents the same edge.
• Left and right direction — the left-hand and right-hand versions are both available, so a two-sided station is covered by one part code.
• Single mounting hole — one hole through the insert, clamped by the holder's screw; replacement is a screwdriver job.
• Insert only, holder stays — you replace the 2 mm carbide blade and keep the holder, which is where the cost of a station sits.
• Scraper station, not a cutting head — it fits the scraping or glue-line position behind the trimming cutters, and does not replace them.
• Melamine, PVC, ABS, veneer — sold as the scraper insert for those four edge materials, used after the trimming cut.
• Marked for identification — 12X17X2-R2 is on the insert itself, so similar blades in one drawer cannot be mixed up.

The choice on a worn scraper is usually bad either way: keep running it and the glue line shows, or stop the station and send it out. Here is what changes.

• You stop losing a station to one worn edge. A 17 x 12 x 2 mm insert is a consumable, so a spare on the shelf keeps the station running through the shift.
• Your edge stops depending on who honed it. The 2 mm radius arrives ground, so the panel profile after the first change matches the tenth.
• You buy a blade, not a station. Holder, screw and setting stay where they are; only the carbide insert is replaced.
• Both sides of the station are covered. Left-hand and right-hand direction come from one part code, so a two-sided setup needs no second document.
• No mix-ups on the floor. 12x17x2-R2R checks against the marking on the insert itself, which is what an operator reads at the bench.
• Changing board does not change the blade. Melamine, PVC, ABS and wood veneer are what the insert is sold for, so one part covers the material range.
• Quantity decides the price. Price is quotation on request, so the hand direction and the volume you run are agreed before the order, not after.

It is the size and the edge radius in one code. 12 mm wide, 17 mm long, 2 mm thick, with a 2 mm radius on the cutting edge; the trailing R2R marks the left-hand and right-hand direction.

Only if the holder is machined for a 12 x 17 x 2 mm insert with a 2 mm radius edge. Measure the old blade before ordering, or send us the holder code and we confirm it against 12x17x2-R2R.

Yes, order the side your station carries, and both are available on the same part code. The R2R suffix in 12x17x2-R2R is there so the direction is never guessed on an order.

Yes, those three are part of the stated application range, together with wood veneer. The insert takes the leftover glue bead after the trimming cutters, so the edge material changes but the scraper pass does not.

Just the insert knife. The 2 mm carbide blade is the part you replace; the holder, its screw and its setting stay on the machine.

Because the 2 mm section has to hold an edge against an abrasive glue line for a whole run rather than a few panels. Carbide is the material the insert is made from, and it is why the part is sold as a consumable insert.

Other sizes are a separate enquiry, and the confirmation point is always the holder. Send the old blade's length, width, thickness and radius, and we answer against 12x17x2-R2R before anything is quoted.

Send the part code 12x17x2-R2R, the hand direction you need and the quantity you run per year. Price is quotation on request, and the part is confirmed against your holder before you commit to an order.
