20x15.8x2mm Tungsten Carbide Indexable Blade CEHISA Edge Bander Scraping Blade

Need a scraping blade that drops into a CEHISA edge bander without re-setting the station? This insert is 20 x 15.8 x 2 mm with a 4.4 mm fixing hole, cut from tungsten carbide and supplied in R1, R2 or R3 corner radius. It scrapes residual glue, trim marks and the fine step off the banded edge, so the corner reads flat at packing. Packed 10 pcs per box, plastic box inside a carton, other sizes and radii quoted on request.

A shop running a CEHISA edge bander meets the same three things when the scraping station wears: a glue line that shows through the lacquer, an operator re-setting the blade by eye after every changeover, and panels that reach packing with a fine step along the edge. A dull scraper never stops the machine. It just sends every panel out with a shadow on it.

This 20 x 15.8 x 2 mm insert removes all three. It seats in the scraping unit of a CEHISA edge bander, where the 2 mm carbide body scrapes residual glue, trim marks and the step left by the trimming cutters off the banded edge. The cutting corner and the body are one piece of tungsten carbide, so the material doing the scraping runs through the full thickness.

One blade carries one corner radius: R1, R2 or R3, chosen to match the radius already set on the machine. The 4.4 mm through-hole locates on the existing clamp screw, so a replacement is a screw-out, screw-in job at the station rather than a fresh setup.

Blades ship 10 pcs to a box, plastic box inside a carton, which puts a spare within reach of the operator instead of in a stores queue. Other dimensions and radii are quoted on request, and shipping runs by air, by sea or by express.

What separates this insert from a generic scraper is how the three dimensions line up with the seat, the screw and the radius the machine already runs.

• Solid carbide edge — the corner that touches the panel is tungsten carbide through the whole 2 mm of the body, not a layer on steel.
• 20 mm cutting length — one continuous scraping edge spans the band width in a single pass.
• 15.8 mm body height — the insert sits down in the clamping seat and meets the holder face to face.
• 4.4 mm fixing hole — a single through-hole lines up with the clamp screw, so the blade locates on the screw instead of on the operator's eye.
• Three radius options — R1, R2 and R3 cover the corner radii used on CEHISA scraping stations, and each radius is ordered as its own item.
• Shaped for CEHISA machines — the insert is made for the scraping unit of CEHISA edge banders, not for a generic holder.
• Cleans up after trimming — the edge scrapes residual glue, trim marks and the fine step off the banded panel.
• Boxed 10 pcs — one box keeps ten spares at the machine, so a worn corner is a screwdriver job.
• Custom sizes quoted — other dimensions, hole diameters and radii are made to order on request.

A worn scraper leaves two choices: keep running and accept the glue shadow, or stop the line and wait for a delivery. A boxed insert removes both.

• A spare at the station, not in transit. 10 pcs per box means a blade change costs a screwdriver, not a purchase order and a week of waiting.
• The radius you already run. Order R1, R2 or R3 and the corner matches the setup instead of being worked around.
• No re-setting after a change. The 4.4 mm hole locates on the existing screw, so the new blade goes back in the same position as the one it replaced.
• The edge leaves the station flat. Glue line and trim marks come off at the blade, before the panel reaches packing and the customer.
• Small part, small stock. A 20 x 15.8 x 2 mm insert takes a corner of one drawer, so holding two radii side by side costs shelf space rather than cash.
• Custom when the seat is different. Other dimensions and radii are quoted on request, so a non-standard holder is a question rather than a dead end.

Yes, if the scraping station takes a 20 x 15.8 x 2 mm insert with a 4.4 mm hole. Check those three numbers against the blade you are taking out, and confirm the corner radius is R1, R2 or R3.

Order the radius that matches the setup already on your machine. The blade is supplied in R1, R2 or R3, so read the corner radius off the old insert or the scraper holder before ordering.

It cleans the edge after trimming. The trimming cutters size the band, then the scraping insert removes residual glue, trim marks and the fine step they leave behind.

Because the cutting corner is carbide through the full 2 mm body, so the material at the contact point is the same material as the rest of the insert.

Ten. Inserts are packed 10 pcs to a box, which is enough for a spare set at the scraping station.

Plastic box first, then carton. Shipments go by air, by sea or by express, whichever suits the order size.

Yes. Custom sizes, hole diameters and radii are quoted on request; send the dimensions and the radius you need.

Power the machine off and disconnect it before you touch the insert. Then release the clamp screw through the 4.4 mm hole, lift the old blade, seat the new one on the screw and tighten it back to the holder.
