Corner rounding router bit work on solid surface edges where there is access to a flat reference face, giving you a controlled profile instead of a hand-shaped edge. This Amana Tool 1-1/8 x 5/16 radius corner rounding bit is designed for solid surface material, so its geometry supports typical countertop edge shaping tasks. The Ultra-Glide non-marring bearing references the flat surface as you cut, helping the profile stay consistent over long runs on straight or gently curved sections. The 2-flute design provides two cutting edges, which helps the bit track smoothly as you move along the workpiece. A 1/4 inch shank lets this bit fit routers built for that shank size, so it can be used in lighter-duty router setups that accept small shank tooling.
This Amana Tool corner rounding router bit uses its Ultra-Glide non-marring bearing to ride against a flat surface, so setup focuses on exposing the correct portion of the 5/16 inch radius past the workpiece edge. With the 1/4 inch shank, the bit seats into a router collet sized for that shank, which establishes a stable hold for edge passes. The 2-flute cutting layout distributes cutting load between two edges, helping the bit maintain a predictable feel as you run along the solid surface edge. Together, the bearing guidance and fixed radius shape support consistent edge profiles from piece to piece once the height is dialed in for the desired round-over.
This solid surface router bit is used where there is a flat surface for the Ultra-Glide non-marring bearing to reference, so it fits naturally into countertop and similar panel work. It is designed to work in concert with either a countertop no-drip design bit or a corner-rounding bit with a radius bearing, so it becomes part of a two-bit sequence rather than a stand-alone profile tool. When run as part of that sequence, this bit participates in producing a no-drip edge or a bull nose in two passes, so it supports typical solid surface edge treatments used on horizontal worktops. Being in the router bits product class with a defined 5/16 inch radius, it helps standardize these edges across multiple tops or runs.
The Ultra-Glide non-marring bearing guides along the flat solid surface, so the 5/16 inch radius is applied at a steady offset from the face instead of wandering, which helps control the edge reveal. Working with a countertop no-drip design bit or a radius-bearing corner-rounding bit in a two-pass sequence, this bit contributes one of the stages needed to build a no-drip edge or full bull nose, so the overall edge form is broken into manageable routing steps. The 2-flute layout means two cutting edges contact the material on each rotation, which supports a balanced cut as you advance along the edge. With the 1-1/8 inch overall cutting diameter establishing the profile envelope, installers can plan the edge build-up and overhang around a known tool size.
This Amana Tool 57150 router bit is described for solid surface, so it is suited to routing edge profiles on solid surface countertop and panel materials.
The Ultra-Glide non-marring bearing rides on a flat solid surface, guiding the bit while avoiding marks on finished faces and helping the 5/16 inch radius stay consistent.
This corner rounding bit works with a countertop no-drip design bit or a radius-bearing corner-rounding bit to produce a no-drip edge or a bull nose in two passes.
The 5/16 inch radius defines how much the corner is eased, giving a controlled rounded edge commonly used on solid surface countertops for a comfortable, finished feel.
The 1/4 inch shank is sized for routers with a matching collet, so it fits router bodies designed for small-shank bits used in edge shaping work.
The Amana Tool 57150 designation identifies this exact 1-1/8 x 5/16 radius solid surface corner rounding bit, simplifying reorders and alignment with shop standards.
The Amana Tool corner rounding router bit with Ultra-Glide non-marring bearing is set up for solid surface edge work where a flat reference face is available, so it aligns well with countertop fabrication tasks. Its 5/16 inch radius and 1-1/8 inch cutting diameter define a repeatable profile, which supports consistent no-drip or bull nose edges when used in a two-pass sequence with the related bits. With a 1/4 inch shank and 2-flute geometry, it fits routers sized for that shank and provides a controlled cut for routine edge runs.
