corner rounding bit 1/4 radius describes this Amana Tool 2 inch x 1/4 inch Radius Corner Rounding Bit with Ball Bearing Guide, 2-Flute, 1/4 inch Shank, giving you a defined 1/4 inch radius edge on your workpiece so edge profiles stay consistent from part to part. This basic edge-forming bit is designed to round an edge to a given radius, so you can produce a controlled, repeatable curve on cabinet parts, furniture components, or shop projects. The bit cuts a fillet along with the radius, adding a small, straight land that visually breaks the edge and helps transitions look intentional on finished parts. This same cut can be used simply to ease edges so they are more comfortable to handle, or as a simple profile that stands on its own on visible fronts. It also serves as part of a more complex profile, letting you build layered shapes in multiple passes.
This Amana Tool router bit uses a ball bearing guide, so the bearing rides the workpiece edge and controls the cut path, which helps maintain a straight, steady profile even when following curved stock. The 1/4 inch shank specification fits routers that accept 1/4 inch shank tools, letting the bit mount securely for typical edgeforming operations. A 2-flute cutting layout spreads the cutting action around the rotation, which supports smoother edges and helps reduce visible step marks along the fillet and radius. Because the bit is a basic edge-forming design, setup focuses on projecting the profile to the correct depth so the 1/4 inch radius and fillet land exactly where you want them on the stock thickness.
This corner-rounding bit is categorized under Bits, Blades and Cutters in the Edgeforming class of router bits, so it is built for shaping exposed edges on wood components. Its 2 inch size and 1/4 inch radius suit work where a moderate round over is needed, such as cabinet doors, shelves, or trim where you want a defined curve without removing excessive material. The ball bearing guide makes it well suited to following template edges or finished workpiece edges, giving control when tracing patterns or working on assembled parts. As a basic edge-forming bit, it fits into general woodworking, cabinetmaking, and shop fabrication where a standard 1/4 inch round over is part of the shop profile set.
The 1/4 inch shank on this Amana Tool router bit gives a known interface to routers designed for 1/4 inch tools, so the grip length and fit are predictable for repeat setups. Its 2-flute configuration balances cutting forces, which supports a smoother feed and helps edges come off the router with less cleanup. The bit is described as also known as round over, rounding over, and quarter-round, so drawings or cut lists using any of these terms still match the same 1/4 inch radius tool, reducing confusion in the shop. If a smaller pilot bearing is used, the bit can produce a second shoulder and act as a beading bit, which means the same cutter body can form both a simple round over and a bead profile by changing the bearing size. That bearing-guided flexibility lets you standardize on one profile radius while still varying the visual detail across different projects.
The corner-rounding bit is a basic edge-forming router bit that rounds an edge to a given radius, making it suited to shaping exposed edges on woodworking and cabinet components.
The Amana Tool bit produces a 1/4 inch radius, so every pass creates a consistent quarter-round profile that can be matched across multiple parts in the same project.
The ball bearing guide rides along the workpiece edge, controlling the cutting path so the radius and fillet follow the stock accurately, which supports cleaner, more uniform edges.
This corner-rounding bit uses a 1/4 inch shank, fitting routers that accept 1/4 inch shank router bits for typical edgeforming operations in woodworking.
The corner-rounding bit can act as a beading bit when a smaller pilot bearing is used, adding a second shoulder so you can form a bead profile from the same cutter body.
The bit cuts a fillet along with the radius, creating a small flat that sharpens transitions between faces and curves, helping finished edges look intentional and well-defined.
The Amana Tool 2 inch x 1/4 inch Radius Corner Rounding Bit with Ball Bearing Guide, 2-Flute, 1/4 inch Shank provides a defined 1/4 inch radius and fillet whenever an edge needs easing or profiling. Its corner-rounding, round over, rounding over, and quarter-round capability lets you standardize edge details across jobs while the ball bearing guide and 2-flute design support smooth, controlled passes. For woodworking or cabinet projects that call for a consistent quarter-round edge, this edgeforming router bit from Wurth Baer Supply aligns profile, radius, and workflow in a single tool.
