3/4 x 1/8 radius corner round router bit describes a basic edge-forming bit that rounds a workpiece edge to a specific 1/8 inch radius, so you get a consistent, repeatable corner detail across multiple parts. This bit is identified as a corner-rounding bit, so it is designed to cut a curved profile that softens sharp edges, improving the finished feel of cabinet parts, furniture components, and trim. The 3/4 inch sizing and 1/8 inch radius work together to produce a controlled, shallow round over that eases edges rather than removing large amounts of material, which supports cleaner passes on edgeforming setups. Because the bit is also known as a round over, rounding over, and quarter-round, it fits a range of common edge profile descriptions used in shops, reducing confusion when matching an existing profile on a job.
This router bit uses a 1/2 inch shank, which matches routers and collets sized for 1/2 inch tooling, giving the bit a solid grip in typical shop routers. The 1/2 inch shank design helps keep the bit stable at the cut, which supports smoother edgeforming when running longer workpieces or repetitive cabinet parts. As a 2-flute configuration, the bit presents two cutting edges to the material, giving a balance of cut quality and feed rate well suited to edge-forming work. That 2-flute layout means each flute takes a moderate chip load at typical feed speeds, which supports clean results when easing or profiling edges as part of your routing workflow.
This corner-rounding bit is described as a basic edge-forming bit, so it is suited to straightforward rounding tasks on cabinet, furniture, and trim edges where a consistent 1/8 inch radius is required. Because the bit creates a cut that can be used to ease edges, it works well on visible or touch surfaces such as shelf fronts, table tops, or door rails, where softening the corner improves handling and appearance. The same cut functioning as a simple profile means you can run it as the only decorative operation on parts that only need a modest radius detail, keeping the routing process efficient. Since the tool is also called a round over, rounding over, and quarter-round, it aligns with common edge names used on drawings and in field notes, which helps match an existing 1/8 inch round profile when doing repairs or additions.
The 1/8 inch radius specified for this corner-rounding bit defines how much material is removed at the edge, giving a small, controlled curve that eases sharp corners without heavily reshaping narrow stock. As a 2-flute router bit, it has two cutting edges, which supports smooth edgeforming while still allowing practical feed rates on longer cabinet parts or trim runs. The product description notes that if a smaller pilot bearing is used, a second shoulder can be produced, effectively turning the tool into a beading bit; this lets you generate a bead plus fillet detail using the same cutter body. That ability to function as a beading bit means the same tool can support both simple round overs and more defined profiles, which can reduce tool changes in a sequence of routing operations.
The 1/8 inch radius sets the size of the rounded edge, so each pass produces a small, uniform curve that eases sharp corners without taking too much material from cabinet or furniture parts.
The 1/2 inch shank fits routers with a 1/2 inch collet, giving the bit a solid hold in the tool, which supports stable edgeforming when running longer workpieces or repeated passes.
The 2-flute design provides two cutting edges, balancing cut smoothness and feed rate so edgeforming passes stay efficient while maintaining a clean, consistent profile along the workpiece.
This corner-rounding bit creates a single round edge that functions as a simple profile, so one pass provides the finished decorative edge on shelf fronts, rails, and similar parts.
The cut from this bit can be used as part of a complex profile, allowing you to combine this radius pass with other routing operations to build layered moldings or custom edge details.
Using a smaller pilot bearing produces a second shoulder, effectively turning the tool into a beading bit that creates a bead plus fillet detail in one routing operation.
The 3/4 x 1/8 radius corner round router bit from Amana Tool provides a defined 1/8 inch edge radius, a 2-flute cutting layout, and a 1/2 inch shank, giving an edgeforming option suited to rounding, easing, or beading tasks on your next routing job.
