Woodworking Arc shaped Integrated Milling Cutter R30 R18 Curves Router Bit

An arc-shaped integrated milling cutter for cutting curves on a router table or spindle, sized R30 R18 with a 1/2 inch shank. The body is industrial-grade tungsten carbide, so the cutting edge holds its profile through furniture and architectural runs. Before you order, confirm your router collet accepts a 1/2 inch shank, that the R30 and R18 radii match the curves on your drawing, and that the cutter clears your fence or template setup. Send the curve profile and the material you are cutting with your enquiry.

Tear-out and wandering curves on a router table usually trace back to a cutter that flexes or loses its edge partway through a run. When the radius no longer matches the template, every piece needs rework. An integrated arc-shaped cutter holds the R30 and R18 curves in one body, so the profile stays true from the first pass to the last in a batch.

This is a woodworking curves router bit, R30 R18, made from industrial-grade tungsten carbide with a 1/2 inch shank. It cuts curves for furniture making and architectural woodworking. A buyer confirms the fit by checking that the router collet takes a 1/2 inch shank and that the R30 and R18 radii match the drawing.

Mount the 1/2 inch shank in the collet, set the depth against your template or fence, and check the cutter clears the stock before the first cut. A 1/2 inch shank seats in a matching collet and takes the side load of a curve cut. Confirm the R30 and R18 radii against your template before running the batch.

Shipment runs by DHL, FedEx, UPS and similar carriers. No packing or customisation options are stated here, so ask before you order. With an enquiry, send the curve profile with the R30 and R18 radii marked, the material and thickness you are cutting, your router collet size, and the quantity you need.

What the specification fixes, and what it leaves to the machine:

• Curve cutting on router tables — R30 and R18 radii are built into one integrated body, so a single bit cuts both arcs without swapping cutters mid-run.
• Shank fit check — The 1/2 inch shank seats in a matching router collet; check your collet size before the bit goes into the spindle.
• Edge wear on abrasive stock — Industrial-grade tungsten carbide holds the cutting edge through furniture making and architectural woodworking runs on abrasive stock.
• Furniture frame and panel work — Built for furniture making, the R30 R18 profile cuts curved rails, aprons and panel edges that need to match a drawing.
• Architectural curve runs — Architectural woodworking calls for repeatable arcs; the integrated arc-shaped body keeps the R30 and R18 profile consistent across a batch.
• Template and fence setup — Set the depth against your template or fence and check cutter clearance before the first pass on the stock.
• Side load on curve cuts — A 1/2 inch shank takes the side load of an arc cut better than a smaller shank, so the bit stays seated in the collet.
• Batch consistency — One integrated cutter for both radii means the curve stays the same from the first piece to the last in a production run.

What changes on the shop floor when the right part goes back in:

• One bit, two curves. R30 and R18 live in the same integrated body, so the operator stops swapping cutters between arcs and the batch keeps moving without a reset.
• Holds the profile through the run. Industrial-grade tungsten carbide resists edge wear, so the R30 and R18 curves stay on the drawing instead of drifting as the batch goes on.
• Seats firmly under side load. The 1/2 inch shank gives the collet more to grip, which matters when the cutter is pulling through an arc and pushing sideways against the stock.
• Fewer rework pieces. When the radius matches the template from the first pass, curved rails and aprons come off the table ready for assembly instead of the rework pile.
• Cuts both furniture and architectural work. The same R30 R18 cutter covers furniture making and architectural woodworking, so one bit handles curved rails and building trim arcs.
• Fit is checked before the order. Confirming the 1/2 inch collet and the R30 and R18 radii against your drawing before ordering avoids a bit that sits in the drawer.
• Clear enquiry, faster quote. Send the curve profile, material, collet size and quantity with your enquiry, and the reply can address the exact R30 R18 cutter you need.

Check that your router collet takes a 1/2 inch shank. The cutter mounts like any shanked router bit, so the collet size is the fit check that matters before you order.

They are the two curve radii built into the integrated arc-shaped body. Match both to the arcs on your drawing or template before cutting.

Yes, the R30 and R18 profiles are in one integrated cutter. You set the depth and run the arc, so the batch does not stop for a bit swap between radii.

Industrial-grade tungsten carbide. That is the cutting material, and it is what holds the R30 and R18 profile through furniture and architectural runs.

Furniture making and architectural woodworking. It cuts curves in those shops, so curved rails, aprons and trim arcs are the kind of work it handles.

Mount the 1/2 inch shank in the collet, set the depth against your template or fence, and check the cutter clears the stock before the first cut.
