Roughing End Mill Carbide 3 Flutes For Wooden Door Particleboard Hardwood

Cutting keyholes in wooden doors and grooves in particleboard on one router, and swapping bits for every job? The 53944177 roughing end mill carries 3 flutes in a three-edge spiral form, in alloy with a wear-resistant coating, so the chip leaves the slot instead of being re-cut. Named workpieces: wooden door keyholes, particleboard, multi-layer board, hardwood and dense composites, in both cutting and grooving. That is 4 workpiece families on one cutter. Various sizes available; lead time 15 working days; origin China; price on request.

A door shop that cuts keyholes and grooves runs into the same three things: a different cutter for the keyhole, the groove and the hardwood edge; a bit that packs chips into the slot and burns the wall it has just cut; and an edge dull again after one shift. This roughing end mill is built against all three.

It is a 3-flute roughing end mill with a three-edge spiral form, machined in alloy and finished with a wear-resistant coating. Each of the 3 edges takes a short, interrupted bite, and the flute space behind it carries the chip up and out of the slot instead of cutting it twice. Chip removal stays smooth in a deep keyhole, and the coated surface holds edge sharpness through a production run.

The workpiece list is the practical half. The tool is specified for keyhole drilling in wooden doors, and for particleboard, multi-layer board, hardwood and other dense composites, in both cutting and grooving — 3 panel families and one timber family on a single cutter, with clean groove walls because the chip leaves while the edge is still cutting.

Sizes come from the available range, so the cutter is matched to your machine and your job. Lead time is 15 working days, origin China, price on request — one part number on the shelf and one cutter at the spindle.

What this cutter is, in eight lines.

• Three flutes — flute count 3, so three edges are in the wood and three flutes are clearing the chip at the same time.
• Three-edge spiral roughing form — each edge takes a short, interrupted bite, and the load per edge stays low in hardwood and dense composite.
• Smooth chip removal — the chip is lifted out of the slot behind the edge instead of being re-cut, which is what keeps a deep keyhole clear.
• Wear-resistant coating — the coated surface lowers friction at the contact point, so the edge stays sharp through a production run.
• Alloy body — material is alloy, so strength sits in the body, not in a surface layer.
• Wooden door keyhole drilling — the first named job on the list: a 3-flute cutter that clears its own chips in a blind keyhole.
• Panel and hardwood range — particleboard, multi-layer board, hardwood and dense composites: 4 workpiece families on one cutter.
• Cutting and grooving — the same edge that drills the keyhole cuts the groove, so the change-over between the two operations goes away.

Today the choice is usually one cutter per operation, or an outside shop for the groove. This tool collapses that list.

• One cutter where the job asked for three. Keyhole, panel cut and groove all run on the same 3-flute edge, so the tool change between them disappears and the setup stays where it was set.
• Chips leave, so the slot does not burn. The chip is carried out behind the edge rather than re-cut in the slot, which is what stops the burn mark on the wall of a deep keyhole.
• Wooden door keyholes come out clean. Keyhole drilling is the first named application, on a cutter with 3 flutes of chip room behind the edge.
• Hardwood stops stalling the cycle. The spiral form splits the load across 3 interrupted bites, so the same cutter that runs particleboard stays in hardwood and dense composite.
• The edge is still there at the end of the run. The wear-resistant coating on the alloy body is what keeps sharpness after a full production run, not just on the first panel.
• Your size, not a shelf size. Various sizes are available, and the size is fixed against your spindle and your groove width when you order.
• Quoted in writing before you pay. Price is on request and lead time is 15 working days, so size, quantity and date are agreed on one document.

Wooden door keyholes, particleboard, multi-layer board, hardwood and other dense composites — in both cutting and grooving. Those are the workpieces named in the specification, so the tool is not being offered outside them.

Three. The cutter is a 3-flute roughing end mill with a three-edge spiral form, so there are three edges in the cut and three flutes clearing the chip at once.

The size that matches your collet and the groove width you need — the cutter is offered in various sizes, and the exact one is fixed with you on the quotation. Tell us your spindle and the groove width, and the size is picked from that, not from a guess.

Yes. The spiral flute carries the chip up and out of the slot behind the cutting edge instead of cutting it a second time, which is exactly the problem in a blind keyhole where a straight-flute bit packs the chips in the bottom.

Alloy, with a wear-resistant coating — that is the material specified for this part. The title carries the word carbide because that is how the cutter is listed and searched; if your process needs a named carbide grade, confirm it with us on the quotation before ordering.

Yes. Cutting and grooving are both listed applications on this tool, on particleboard, multi-layer board, hardwood and dense composites, so the keyhole and the groove run on one 3-flute cutter.

15 working days, from China. That is the lead time given for this part; the shipping method and the delivery date are confirmed on the quotation, since they depend on the quantity you order.

Price is quoted on request — that is the only price term given for this part — and the MOQ, packing and payment terms are fixed on the same quotation. Send the size and the quantity, and the quote comes back with all of them stated.
