corner rounding bit 1/4 radius describes this Amana Tool 2-7/16 inch x 1/4 inch Radius Corner Rounding Bit with Ball Bearing Guide, which shapes edges to a controlled 1/4 inch radius so edges stay consistent from part to part on profiling work. This bit is a basic edge-forming bit, so it focuses on rounding an edge cleanly without adding extra, unwanted shapes on cabinet or woodworking projects. The built-in ball bearing guide rides along the workpiece edge, which keeps the 1/4 inch radius profile tracking true without constant fence adjustments during routing. The bit cuts a fillet along the rounded edge, which defines a small flat between the curve and the face so the transition looks intentional instead of washed out. This same cut can be used to ease sharp edges, to create a simple profile, or to serve as one element in a more complex multi-step edge profile.
This router bit uses a 1/2 inch shank, which gives a solid grip in 1/2 inch collet routers so the 1/4 inch radius profile runs smoothly along cabinet parts or trim. The ball bearing guide at the tip acts as a pilot on the workpiece edge, which maintains the position of the cutting edges so the corner rounding stays aligned even when following curved or straight edges. With a 2-7/16 inch overall size, the bit provides enough reach for standard edge profiling while still feeling manageable on handheld or table-mounted router setups. The 2-flute cutting layout means two cutting edges share the work, which supports a balanced cut across the edge profile when routing typical woodworking materials.
This Amana Tool corner-rounding bit is categorized under Bits, Blades and Cutters in the Profiling class of Router Bits, which places it squarely in edge-shaping tasks for woodworking projects. The 1/4 inch radius is sized for easing cabinet doors, drawer fronts, and shelving edges, giving them a softened feel without removing too much material from the profile. As a basic edge-forming bit, it suits applications where the routed edge needs to complement, rather than dominate, the overall design of casework or furniture. The fact that it is also known as a round over, rounding over, and quarter-round bit ties it to standard shop uses like softening table tops, trim edges, and panel perimeters. When the cut is used as a simple profile, it can stand alone on painted or clear-finished work, maintaining a straightforward, professional edge shape across multiple components.
The bit rounds an edge to a given 1/4 inch radius, which locks in that dimension so matching pieces can be run at different times and still share the same edge profile on finished assemblies. Cutting a fillet along the radius creates a small flat that helps hide minor sanding variation, because the distinct break between flat and curve shows where the edge should finish. When used as part of a complex profile, this corner round can be combined with other passes to build up traditional or custom moulding shapes while keeping the 1/4 inch radius constant. The ball bearing guide keeps the cut located at the edge, which reduces the need for complex fence setups when repeating the same profile on multiple parts. If a smaller pilot bearing is used, a second shoulder can be produced, effectively turning the bit into a beading bit that adds a defined bead and shoulder, allowing one cutter body to create both round-over and bead-style profiles on different jobs.
This corner-rounding bit rounds an edge to a given 1/4 inch radius and cuts a fillet, producing a controlled round-over with a small flat that gives edges a clean, intentional transition.
The ball bearing guide rides the workpiece edge, keeping the cutting edges properly aligned so the 1/4 inch radius and fillet track consistently along straight or curved edges during profiling.
The 1/2 inch shank provides a solid grip in a matching router collet, helping the bit run smoothly while forming the 1/4 inch radius profile on cabinet or woodworking components.
If a smaller pilot bearing is used, this bit can produce a second shoulder, in effect making it a beading bit that adds a bead and shoulder detail to the edge profile.
The bit can serve as a part of a complex profile by contributing the 1/4 inch radius and fillet, which can be combined with other router passes to build multi-step edge shapes.
The tool is also known as round over, rounding over, and quarter-round because it creates the familiar softened, quarter-round edge commonly used to ease sharp corners on woodworking projects.
The Amana Tool 2-7/16 inch x 1/4 inch Radius Corner Rounding Bit with Ball Bearing Guide and 1/2 inch shank offers a defined 1/4 inch radius, a fillet, and a guided cut that together support consistent profiling work. As a basic edge-forming bit that is also known as round over, rounding over, and quarter-round, it suits projects where clean, repeatable edge easing is important. Using this 2-flute corner-rounding router bit as either a simple round-over tool or, with a smaller pilot bearing, as a beading bit, keeps one profile source handling multiple edge treatments.
