corner rounding bit 1/16 radius from Amana Tool is a basic edge-forming router bit designed to round an edge to a given radius, so you can create consistent corner breaks across your work. This 1-3/4 inch x 1/16 inch radius corner rounding bit with ball bearing guide controls the cut along the edge, which helps keep profiles uniform on long runs or repeat parts. The bit is a 2-flute design, so it cuts a fillet as it profiles, giving you a small flat that can read as a simple detail on furniture or casework. This edge-forming profile can be used to ease sharp edges for touch-friendly parts, to create a straightforward decorative profile, or to form one component of a more complex molding build-up on a router table or handheld router.
The bit has a diameter (D) of 1-5/8 inch, so the cutting circle is sized for substantial edge coverage while staying manageable on cabinet-scale work. The radius (R) is specified as 9/16 inch, so the rounded portion of the cut follows a consistent curve that can be repeated across multiple components when you set up a fence or bearing-guided pass. The cutting height (B) is 3/4 inch, giving vertical coverage that suits common material thicknesses used in cabinetry and furniture components. A shank (d) of 1/2 inch provides a stout interface in compatible routers, which supports the cutting geometry during profiling passes. Overall length (L) is 2-5/8 inch, so the bit presents a compact profile in the collet while still reaching the full cutting height in typical router setups.
This Amana Tool corner-rounding bit is positioned as a basic edge-forming bit, so it fits naturally into general cabinet and furniture workflows where easing or profiling exposed edges is routine. Its 1-5/8 inch diameter and 3/4 inch cutting height line up with work on door frames, face frames, shelves, and top edges, where you want enough cutter engagement to shape the edge without overwhelming smaller components. The bit is described as creating a fillet as it rounds, so each pass yields a rounded edge and a shoulder that can visually tie together rails, stiles, or trim pieces on a project. Because it is also known as a round over, rounding over, and quarter-round bit, it aligns with standard shop naming when matching an existing profile specified as a round-over or quarter-round detail on drawings or replacement parts.
The bit uses a ball bearing guide, so the bearing rides the workpiece or template and controls the edge-following action, which supports consistent profiles across identical parts without constant fence adjustment. The 2-flute construction means two cutting edges share the work, distributing the cut as the bit forms the radius and fillet, which promotes a smooth-feeling pass when profiling typical woodworking materials. The web description notes that if a smaller pilot bearing is used, a second shoulder can be produced, in effect making the bit a beading bit, so a bearing change can convert the simple corner-round into a bead profile when you want a more articulated edge on panels or doors. The defined radius (R) of 9/16 inch and the 3/4 inch cutting height together establish a repeatable geometry, so once the router setup is dialed in, you can run multiple components and expect the same edge detail on every pass.
The bit is described as a basic edge-forming bit that rounds an edge to a given radius, so it is intended for general edge easing and profiling on woodworking and cabinet components.
The bit has a ball bearing guide, so the bearing follows the edge or template and controls the path of the cut, which helps keep the rounding profile consistent from part to part.
The corner-rounding bit rounds an edge to a given radius and cuts a fillet, so the finished edge shows a smooth radius with a defined small flat shoulder at the transition.
The web description states it is also known as round over, rounding over, and quarter-round, so the resulting cut matches those common quarter-round style edge descriptions.
The description notes that if a smaller pilot bearing is used, a second shoulder can be produced, in effect making the bit a beading bit for more detailed edge work.
The diameter is 1-5/8 inch and the cutting height is 3/4 inch, so the bit covers a substantial edge width and vertical height on typical cabinet and furniture components in one pass.
This Amana Tool 1-3/4 inch x 1/16 inch radius corner rounding bit with ball bearing guide and 2-flute design is set up for rounding edges, cutting a fillet, and handling round over or quarter-round style work. With its defined diameter, radius, cutting height, and 1/2 inch shank interface, it is suited to edge-forming passes on typical cabinet and furniture components where consistent profiles and straightforward setup matter.
