corner rounding bit 3/16 radius from Amana Tool is a basic edge-forming router bit that rounds an edge to a defined 3/16 inch radius, so you get a consistent, repeatable profile on your workpieces. The bit is designed to cut a fillet as it rounds the edge, which creates a clean transition that reads well on finished cabinetry and furniture. With a 2 inch size format and a 1/4 inch shank, this router bit fits common light and mid-duty router setups used in shops and on site. The 2-flute design provides a balanced cutting action, which helps produce smoother edges and reduces the time needed for cleanup sanding. This corner-rounding profile can be used as a simple eased edge or built into a more complex multi-step profile when a job calls for additional detail.
This Amana Tool router bit uses a 1/4 inch shank, so it fits routers and collets designed around that common size, which helps it drop into many portable and bench-mounted machines. A ball bearing guide is built into the bit, allowing the profile to follow the workpiece edge without separate fences when you are working along straight or curved stock. That bearing-guided setup helps maintain the 3/16 inch radius and fillet location from piece to piece, supporting consistent results across cabinet runs or repeat production work. The 2-flute construction contributes to controlled feed and surface finish, keeping the edge-forming cut smooth along the guided path.
This 2 inch x 3/16 inch radius corner rounding bit works wherever an eased or rounded edge is needed as part of a profiling job. It can be applied as a simple profile on exposed panel edges, rails, or shelves, giving parts a softer edge that is more comfortable to handle. Because the bit rounds to a specific 3/16 inch radius, it helps keep visual alignment consistent when matching edges across cabinet components in the same run. The fillet created by this cut adds a small step detail that separates the rounded area from the flat face, which can help painted and stained finishes catch light in a more defined way. As a basic edge-forming router bit, it fits well into general shop routing workflows where a reliable corner-round is frequently used.
The ball bearing guide on this corner-rounding bit lets the tool track the workpiece edge directly, which helps repeat the 3/16 inch radius without constant fence adjustment during profiling runs. With 2-flute construction, the bit makes its edge-forming cut in a balanced way, which supports a smoother surface that needs less sanding before finishing. When the profile is used as a simple round over, it delivers a uniform eased edge that meets many standard design expectations for doors, drawer fronts, and trim. The same bit can serve as part of a complex profile by combining its cut with others, so one tool can handle both straightforward rounding and more detailed designs. If a smaller pilot bearing is used, the bit produces a second shoulder and effectively becomes a beading bit, adding another step detail that expands the range of decorative edges possible from the same cutter.

The ball bearing guide follows the workpiece edge, keeping the 3/16 inch radius and fillet aligned along the cut so edge profiles remain consistent across parts.
This corner rounding bit uses a 1/4 inch shank, allowing it to be mounted in routers and collets sized for 1/4 inch tooling.
This router bit can function as a beading bit when a smaller pilot bearing is used, producing a second shoulder and adding an additional decorative step.
