Amana Tool corner rounding router bit is a basic edge-forming bit that rounds an edge to a given radius, so you can create consistent, repeatable edge profiles on wood components. This edge forming corner rounding bit uses a ball bearing guide, which follows the workpiece edge as it cuts and helps maintain a steady profile in routing setups. The corner-rounding bit cuts a fillet as it rounds the edge, so you get a clean transition between the face and the rounded edge. The cut can be used to ease sharp edges for safer handling, as a simple decorative profile on visible parts, or as part of a more complex multi-step profile in a workflow. Also known as a round over, rounding over, or quarter-round bit, this tool fits directly into 1/2 inch router collets for secure mounting.
This corner rounding router bit has a 1/2 inch shank, which fits 1/2 inch router collets and provides a solid grip for profiling cuts. The overall diameter is 3 inches, so the cutting circle is large relative to typical small edge bits and is suited to substantial rounding work. Cutting height is 1-1/2 inches, allowing the radius and fillet to work along a tall edge in a single guided pass. Overall length is 3-1/4 inches, giving enough projection from the collet for the 1-1/4 inch radius and fillet geometry. The bit is specified as not for use in a handheld router, directing it toward stable, controlled routing setups where the workpiece feeds past the guided cutter.
This router bit is identified as a basic edge-forming corner rounding bit, so it slots naturally into edge profiling stations on router tables or similar machines. The 1-1/4 inch radius determines how much material the bit removes from the edge, so it works well where a pronounced round is required rather than just breaking an edge. Because the cut can be used to ease edges, it suits parts that are frequently handled, such as exposed cabinet ends or trim pieces. When used as a simple profile, the radius and fillet give a single-pass decorative edge that reads cleanly on thicker stock. The cutting height of 1-1/2 inches lets the round and fillet extend along deeper edges, which is useful on wider rails or solid stock parts.
The ball bearing guide on this bit tracks the workpiece edge during the cut, so the radius follows the same line on each pass and supports repeatable setups across multiple parts. The fillet created along with the round gives a positive reference detail that shows exactly where the profile terminates relative to the face, which helps keep visual alignment consistent across assemblies. If a smaller pilot bearing is used, a second shoulder can be produced, in effect making the bit a beading bit, giving you another profile option from the same cutting geometry. The 1/2 inch shank supports the 3 inch diameter cutting circle with a solid grip, which is important when shaping a 1-1/4 inch radius in one pass. The not for use in a handheld router note directs this bit to fixed routing equipment, which supports steadier feeding and more controlled profiles on larger radius cuts.
The Amana Tool 49524 is a basic edge-forming corner rounding router bit that rounds an edge to a given radius and cuts a fillet for profiling work.
This router bit has a 1-1/4 inch radius and a 3 inch diameter, so it produces a large corner round suitable for substantial edge shaping in a single pass.
The ball bearing guide follows the edge of the workpiece, keeping the corner rounding profile and fillet consistent without relying solely on fence settings.
This corner rounding bit can produce a second shoulder when a smaller pilot bearing is used, in effect making the bit a beading bit for added profile options.
The Amana Tool 49524 uses a 1/2 inch shank, so it mounts in routers or collets designed for 1/2 inch shank tooling in profiling setups.
This router bit is specified as not for use in a handheld router, directing it toward fixed routing equipment where the workpiece is guided past the cutter.
The Amana Tool edge forming corner rounding bit with ball bearing guide delivers a 1-1/4 inch radius and fillet for defined edge easing and profiling work. With its 1/2 inch shank, 3 inch diameter, and 1-1/2 inch cutting height, it fits routing setups focused on larger, shaped edges. Choose this router bit when a pronounced round over, quarter-round, or beading-style option from the same tool will support your cabinet or woodworking runs.
