Edge Forming Bullnose Carbide Tip Bit is a router bit from Amana Tool designed for shaping stair treads, window sills, table and counter edges, shelves, and making moldings, so one profile tool handles multiple common trim jobs. The bit uses a carbide tip and 2 flute cutting design, which cuts the edge profile while helping maintain a consistent finish across hardwood and softwood projects. A 1-11/16 inch diameter cutting profile shapes a substantial bullnose, giving stair treads and counters a full, rounded front. The 1/2 inch radius geometry defines the curvature, so you know exactly what edge profile to expect on repeat passes. A 1-9/16 inch cutting height lets you cover deeper edges in a single routing pass where the layout allows. The 1/2 inch shank fits routers that accept this shank size, providing a solid grip in typical professional shop setups.
This Amana Tool 51562 bullnose bit must be used with an edge guide on handheld routers or with the fence on a router table, so the bit cuts while the workpiece stays guided for a straight, repeatable bullnose. The 1/2 inch shank seats into a matching router collet, allowing secure tightening before setting final cutting height. With a 1-9/16 inch cutting height and 1/2 inch radius, router setup can be dialed so the center of the radius aligns with the stock edge you want to round, helping align the bullnose evenly on stair treads, window sills, and counter fronts.
This Edge Forming Bullnose Carbide Tip Bit is described as ideal for shaping stair treads, so its 1/2 inch radius and 1-11/16 inch diameter profile create a rounded nosing that finishes exposed stair edges. The same geometry is described for window sills, meaning the bit can round the outer sill edge for a softer, finished front. For table and counter edges, the 1-9/16 inch cutting height works along thicker top stock, forming a bullnose that transitions smoothly from surface to edge. Shelves can be run against an edge guide or router table fence, and the 1/2 inch shank supports these edgeforming passes in routers sized for that shank. Because the bit is also described for making moldings, its combination of diameter and radius lets you produce repeatable molded strips that carry the same bullnose profile used on treads and tops.
The Amana Tool 51562 part number identifies this specific bullnose bit with a 1-11/16 inch diameter and 1/2 inch radius, so ordering the same number keeps profiles consistent across projects and replacements. The 2 flute configuration means two cutting edges share the work as the carbide tip rotates, which helps distribute the cut and supports smoother surfaces ready for sanding and finishing. With a 1-9/16 inch cutting height and 3-1/16 inch overall length, the bit reaches along the edge of typical stair treads, sills, and counters without overextending the router. The requirement to use an edge guide on handheld routers or a router table fence keeps the work constrained to a straight path, helping prevent wavy edges and improving alignment between multiple parts. The 1/2 inch shank ties these details together by matching many professional router setups, supporting a solid hold and steady cutting action on repeated passes.
The Amana Tool 51562 bit is described as ideal for shaping stair treads, window sills, table and counter edges, shelves, and for making moldings, so it serves multiple trim and finishing tasks.
The bit has a 1-11/16 inch diameter and 1/2 inch radius, so it produces a wide, half-inch bullnose curve suitable for substantial stair, counter, and shelf edges.
The Amana Tool 51562 bit must be used with an edge guide on handheld routers or with the fence on a router table, so the edge profile follows a controlled, straight path.
The 51562 bullnose bit uses a 1/2 inch shank, which fits router collets that accept this size and provides a solid grip for edgeforming work.
The bit has a 1-9/16 inch cutting height, allowing it to cover relatively deep stair, counter, or shelf edges in a single, guided pass when layout permits.
The 2 flute design provides two cutting edges on the carbide tip, helping balance cutting loads and support a smoother finish on visible edge profiles.
The Amana Tool Edge Forming Bullnose Carbide Tip Bit 51562 pairs a 1-11/16 inch diameter profile, 1/2 inch radius, and 1-9/16 inch cutting height with a 1/2 inch shank, giving stair treads, window sills, counters, shelves, and moldings a repeatable bullnose edge when guided by an edge guide or router table fence.
