How to Cut Radius Corners: Precision Techniques for Clean Edges
Achieving smooth, consistent radius corners transforms raw edges into polished, professional designs—essential in furniture making, sign fabrication, and custom woodwork. Mastering this technique ensures durability and aesthetic appeal.
How to Cut Radius Corners with a Router
Using a router with a circular base or template is one of the most effective ways to cut radius corners. Secure your material, clamp it firmly to prevent movement, and use a straight edge or jig to guide the router along the desired curve. Maintain consistent depth and speed for even cuts; start with shallow passes and gradually deepen as needed. For precision, opt for a plunge router paired with a template secured by vacuum or clamps to maintain alignment throughout the process.
CNC Routing for Precision Radius Shapes
For repeatable, high-accuracy radius cuts, CNC routing offers unmatched consistency. Load a pre-programmed 3D model of your radius into the machine’s software, adjust the cutting depth to achieve the full radius, and let the automated tool follow the contour precisely. This method minimizes human error and is ideal for large-scale production or complex designs requiring exact symmetry.
Hand Tools and Jigs for Custom Radius Cuts
For smaller projects, hand tools like a coping saw or template-guided chisel allow fine control. Trace a radius template onto the edge, clamp the material securely, and carefully cut along the arc using a fine-tooth saw. Alternatively, build or use a jig with a curved edge guide to maintain consistent radius depth and alignment, ideal for artistic or bespoke pieces.
Cutting radius corners is a foundational skill that elevates craftsmanship and design quality. Whether using routers, CNC machines, or hand tools, mastering precision cutting ensures clean, durable results. Invest in quality templates and steady technique—your edgework will speak volumes about your expertise.
Situation: you need to cut a radius on a corner of a part but the corner rounding mill doesn't meet the part specs. What do you do? Here's a practical solution. 9.16 Radius Cutting Micky R.

Jennings, courtesy of Wenatchee Valley College, CC BY 4.0 Radius cutting is the process of creating a radius on an edge with a corner rounding tool. This radius is most often created on a 90. Learn how to make wide radius corners using just a jigsaw and a router.
First make a jig or template, cut the excess off with a jigsaw and finally rout a perfect rounded corner. Situation: you need to cut a radius on a corner of a part but the corner rounding mill doesn't meet the part specs. What do you do? Here's a practical solution.
When jobs require producing a radius on the corner of a part, the typical and usually most efficient tool to get the job done is a corner radius forming tool (shorturl.at/goKLU). Radius cutting is the process of creating a radius on an edge with a corner rounding tool. This radius is most often created on a 90-degree corner.
These cuts are used to remove corners that might be damaging to other components, as a design element, or simply for aesthetic reasons. Here I show you how I mill an outside radius on a small part without the use of an outside radius cutter, or a rotary table. This is by no means the only, or best way to cut a radius.
Rout Round Corners Even if you don't own a bandsaw, you can still make a smooth, wide radius on any corner using only a simple jig and your router. Large drill bit, holesaw, forstener bit for the corners, and then cut to the perimeter of the cut out circles. You'll have.
Avery tough time cutting that radius with a jigsaw, maybe a scroll saw on thinner material. Need rounded corners on your metal sheet or plate? Cut2SizeMetals offers knock-off and laser-cut radius corners for safe, custom metal finishing. Are you looking for ways on how to make rounded corners woodworking? Rounded corners can add a touch of elegance and sophistication to your woodworking projects.
Whether you are working on furniture, cabinets, or other wood items, knowing how to create rounded corners can take your craftsmanship to the next level.
