Woodworking Curves Router Bit R30 1/2 Inch Shank Cutting Tools

Need one cutter that produces a finished curve instead of a template, a straight bit and a sanding drum? The R30 curves router bit does it in one pass. R30 profile with an R18 size in the same family, 1/2 inch (12.7 mm) shank, industrial-grade tungsten carbide cutting edge, for furniture making and architectural woodworking. Ships from China by DHL, FedEx or UPS. Price on request.

A curved cabinet corner, a radiused table edge and an arched panel look like one job, but most shops buy three things for them: a template plus a flush-trim bit, a sanding drum, and a hand-finished radius that depends on who is holding the tool. Every extra step costs a setup, and every sanding pass costs a little of the radius that was just cut. The R30 is built to remove that chain.

It is a woodworking curves router bit, also sold as an arc bending router bit. The cutting profile is R30, with an R18 size in the same family, on a 1/2 inch (12.7 mm) shank. The edge is industrial-grade tungsten carbide, which is why the profile keeps cutting in plywood and MDF and not only in clean hardwood.

The 1/2 inch shank is the part a photo does not show. At 12.7 mm across, it deflects less than a 6.35 mm shank over the projection a hand router runs, so the arc holds R30 along the whole sweep instead of drifting at the exit of the pass.

It is a cutting tool for furniture making and architectural woodworking: tabletops, cabinet door edges, frames, mouldings and arched panels. Origin China. Shipment by DHL, FedEx or UPS. Price on request.

What the R30 actually gives you, in numbers:

• R30 cutting profile — one 30 mm radius in a single cutter, so the arc comes off the router already at size instead of being shaped and then sanded back.
• R18 size in the same family — a tighter R18 profile for corners and small returns, ordered in the same bit body style as the R30.
• 1/2 inch shank — 12.7 mm shank diameter for routers with a 1/2 inch collet, the size that keeps a curve stable from entry to exit.
• Industrial-grade tungsten carbide — the cutting edge material, chosen so R30 keeps its shape in plywood and MDF, not only in hardwood.
• Curve and arc work — decorative edge profiling, curved cabinet corners and bent-panel arcs on one R30 cutter.
• Furniture making — tabletops, cabinet door profiles and frame sections where the R30 radius stays visible on the finished face.
• Architectural woodworking — mouldings, arched panels and long runs where the same R30 curve has to repeat piece after piece.
• Four common materials — hardwood, softwood, plywood and MDF with one bit, so a mixed batch does not need a second cutter.
• Shipped by express — DHL, FedEx or UPS from China, on a quote issued per order.

If you finish curves by hand or send them out for shaping, the R30 removes the step you are paying for twice.

• One cutter instead of a template stack. A 30 mm radius leaves the router at R30, so a curve no longer needs a template, a flush-trim bit and a sanding drum in sequence.
• The shank decides whether the curve is repeatable. At 12.7 mm, less of the bit bends under load, so the radius at the end of a sweep matches the radius at the start of it.
• Carbide pays back on board material. Industrial-grade tungsten carbide holds the R30 profile in plywood and MDF, where a softer edge would round over first.
• Two radii cover two drawing sizes. Order R30 and R18 and the common furniture and joinery curves are covered without a third purchase.
• Built for the two jobs that pay for it. Furniture making and architectural woodworking both need the radius visible on the finished face, which is exactly where R30 is used.
• Quoted per order, not per catalogue. Price on request, so a quantity of R30 and R18 bits can be quoted together for one project.
• Shipped the way small tooling should be. DHL, FedEx or UPS from China, so a single bit order does not wait for a container.

Both. The product is listed with two sizes, R30 and R18, and you specify which radius you need when you ask for the quote.

1/2 inch, which is 12.7 mm. It fits routers with a 1/2 inch collet; a 1/4 inch router needs a different bit.

Industrial-grade tungsten carbide. That is the material that keeps the R30 profile in plywood and MDF as well as in hardwood.

Hardwood, softwood, plywood and MDF. Those four cover the furniture and joinery work the bit is made for.

Nothing — they are two names for the same tool. This listing carries both names because buyers search both.

Curved profiles: cabinet corners, tabletop edges, mouldings, frames and arched panels, in furniture making and architectural woodworking.

By DHL, FedEx or UPS from China, confirmed on the order because the carrier depends on the destination.
