49494 corner rounding bit is a basic edge-forming router bit that rounds an edge to a given radius and cuts a fillet, so you can put a consistent eased edge on workpieces without hand sanding profiles. The bit is described as a corner-rounding bit that can be used to ease edges, as a simple profile, or as part of a complex one, which gives flexibility for both straightforward softening passes and layered moldings. It is also known as a round over, rounding over, and quarter-round bit, so it lines up with common trade terms used on drawings and cut lists. The bit has a diameter of 5/8 inch and a 1/16 inch radius, giving a small, controlled round over that is useful where you want edges broken without losing much material. The cutting height of 5/16 inch supports edging on typical stock thicknesses while keeping the profile tight.
The bit has a 1/2 inch shank, which provides a solid grip in routers that accept 1/2 inch bits and supports stable running during extended edge passes. The overall length is 2-1/4 inch, giving enough reach for common table or handheld setups while keeping the cutter compact for control. The design uses a ball bearing guide, so the bearing rides the work edge and sets the path of cut, which simplifies setup for following straight or curved edges without relying solely on a fence. The Web Description notes a dimension D1 of 1/2 inch, tying to the bearing area that interacts with the work and helping relate the guide diameter to template or edge layouts.
The Web Description identifies this tool as a basic edge-forming corner-rounding bit that rounds an edge to a given radius, making it suitable for softening exposed plywood, solid stock, or trim edges that need a small break. With a 1/16 inch radius, it creates a fine round over that is appropriate for doors, drawer fronts, shelves, and face frames where designers want a eased edge without a heavy profile. The 5/16 inch cutting height works well along the edge of typical cabinet components, allowing the full radius and fillet to register without running far down the face. Because it is also described as round over, rounding over, and quarter-round, it aligns with various drawing notes calling for those profiles, helping match specified edges on shop documents.
The bit is specified as 2-flute, which presents two cutting edges to the work, helping distribute cutting action and support a smooth edge finish when the router is set up with appropriate feed direction. The ball bearing guide controls how the profile tracks the workpiece edge, which assists in repeating the same radius along multiple parts and around curves that follow a template. 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, so changing the bearing size gives an alternate profile from the same cutting geometry for consistent decorative beads. The combination of 5/8 inch diameter and 1/16 inch radius defines a compact cutting circle, which helps keep the round over tight and predictable on narrow parts such as rails or narrow trim strips.
The bit is described as a basic edge-forming corner-rounding bit that rounds an edge to a given radius and cuts a fillet, so it is suited to easing and profiling exposed edges.
The 49494 bit has a 1/16 inch radius, producing a small, precise round over that slightly softens sharp corners without creating a large decorative curve.
The bit uses a ball bearing guide, so the bearing follows the workpiece edge or template, helping maintain a consistent 1/16 inch radius profile along straight or curved edges.
The bit has a 1/2 inch shank, fitting routers that accept 1/2 inch shank tools and providing a solid grip for edge-forming passes.
The description notes that using a smaller pilot bearing produces a second shoulder, in effect making the bit a beading bit for a different edge profile.
The bit has a 5/8 inch diameter, 5/16 inch cutting height, 1/2 inch shank, and 2-1/4 inch overall length, which define cutter reach and profile engagement in routing setups.
The Amana Tool router bit with manufacturer part number 49494 combines a 1/16 inch radius, 5/16 inch cutting height, and ball bearing guide to deliver controlled corner rounding. For projects calling for a small round over or quarter-round edge, its 5/8 inch diameter and 1/2 inch shank give a compact, stable cutter. Adding this 2-flute corner-rounding bit to your router setup supports consistent eased edges and the option to create beading when paired with an appropriate smaller pilot bearing.
