Brazed PCD Diamond Carbide Scraping Blade Inserts 4014030041 20X12X2mm for CNC Edge Banding Machine

Need a scraping insert that keeps its edge on abrasive or high-gloss banding? The EB004-BZ brazes a polycrystalline diamond (PCD) tip onto a tungsten carbide body: 20 mm long, 12 mm wide, 2 mm thick, 4 mm inner hole, in R1.5, R2 and R3. It is a direct replacement for 4014030041 / 4-014-03-0041 inserts on CEHISA, SCM, Brandt and HOMAG scraping stations. The carbide carries the load and damps vibration, the diamond does the cutting, so the radius you set is the radius you keep.

A scraping station runs into the same three problems. A plain carbide insert slowly loses its polish on abrasive or high-gloss banding. A chipped edge leaves a drag line that has to be sanded out by hand. A replacement insert that does not sit exactly like the one before it changes the finish from panel to panel. The EB004-BZ scraping blade inserts are built to remove all three.

Each insert is a two-material part: a polycrystalline diamond (PCD) tip brazed onto a tungsten carbide body. The carbide body carries the clamping load and damps vibration, while the diamond tip does the cutting, so the radius holds on PVC, ABS and high-gloss banding. The envelope is 20 x 12 x 2 mm, with a 4 mm inner hole for the clamp screw.

Three edge radii are available: R1.5, R2 and R3. That covers the standard radius scraping positions on a CNC edge banding machine, so one part number family covers all three.

They drop into the seat of 4014030041 / 4-014-03-0041 inserts on CEHISA, SCM, Brandt and HOMAG scraping and edge-finishing stations. The fit is dimensional, not machine-specific: a station that clamps a 20 x 12 x 2 mm insert through a 4 mm hole accepts these. Typical use is furniture, cabinet and panel edges, where the scrape station takes the glue line and overhang off after trimming.

What separates this insert from a plain carbide scraper is the material stack, not the outline.

• Brazed PCD tip on a carbide body — the diamond cutting edge and the tungsten carbide backing are one brazed part, 2 mm thick and 20 mm long.
• 4 mm clamping hole — the insert picks up the original screw and seat, so no adapter plate and no re-machining of the holder.
• R1.5, R2 and R3 in one family — three radius profiles under one model code, ordered to match the cut already running on the machine.
• Carbide absorbs the impact — vibration and shock load go into the cemented carbide body, which is the point where a thin full-diamond insert fails first.
• Diamond edge on abrasive banding — PCD keeps its geometry on PVC, ABS and high-gloss banding, where a carbide edge loses its polish first.
• Cleans up after fine trimming — it takes the glue line and edge overhang off after the trimming cutters, over the full 12 mm edge face.
• Drop-in for 4014030041 / 4-014-03-0041 — same 20 x 12 x 2 mm envelope and 4 mm hole, with R1.5 below R2 and R3 above it.
• One screw to change — remove the old insert, slide in the new one, and the 4 mm hole locates it in the same clamping position.

Buying a scraping insert usually means picking between two unsatisfying options: a plain carbide insert that loses its polish early, or a full-diamond insert that wears well but chips when the holder is not rigid. The EB004-BZ is built for the gap between them.

• Diamond where it cuts, carbide where it loads. Only the tip is PCD; the 20 x 12 x 2 mm body stays a stocked carbide blank, so the wear-critical edge is diamond and the rest of the insert is not.
• The radius stays the radius. A fixed R1.5, R2 or R3 profile means a new insert cuts the same geometry as the one it replaces, so the panel leaving the scrape station does not change with the operator.
• Fewer interruptions on abrasive banding. Diamond holds the edge on PVC, ABS and high-gloss banding, so insert changes follow the banding you run rather than the panel count.
• One part number, three cuts. R1.5, R2 and R3 are held under EB004-BZ, so a station that changes radius does not need a second supplier line or a second minimum quantity.
• Vibration goes into the carbide. Impact and chatter load the tungsten carbide body instead of the diamond tip — the failure mode that takes thin pure-diamond inserts off a scraping station.

Yes, if your scraping station clamps a 20 x 12 x 2 mm insert through a 4 mm inner hole. They are a direct replacement for 4014030041 / 4-014-03-0041 and are used on CEHISA, SCM, Brandt and HOMAG scraping and edge-finishing stations. Check the insert envelope and hole size in your machine manual before ordering.

The cutting edge is PCD diamond instead of carbide. The diamond tip is brazed onto a tungsten carbide body, so the edge gets diamond wear resistance while the body keeps carbide toughness behind it.

Match the radius of the insert you are removing. All three are available under EB004-BZ; if the old insert is worn, measure its radius or send a photo together with the machine model and the position in the station.

No. The body is the same 20 x 12 x 2 mm size and the hole is the same 4 mm, so the insert drops into the existing seat and is clamped by the original screw.

It chips less than a pure diamond insert. The tungsten carbide body absorbs impact and vibration, which is where a thin diamond insert normally fails first.

Send the radius and the quantity you need for a quote. Price is quoted per order because R1.5, R2 and R3 are separate items and the mix changes the total.

Yes. The inserts are used on the scraping and edge-finishing station for PVC, ABS and high-gloss banding in furniture, cabinet, shelf and panel production.

One screw out, one insert in. The 4 mm hole locates the insert in the same clamping position, so routine replacement does not need the seat re-machined or the holder reset.
