Solid surface router bit from Amana Tool is designed as a solid surface round under router bit, so it shapes edges on solid surface stock where a full 180 degree bullnose profile is required. The 2-1/8 inch diameter cutting head engages a wide section of material, which helps form a smooth, continuous curve across the full edge. A 1/2 inch radius profile matches common solid surface edge designs, so finished edges tie in with other standard 1 inch bullnose details. The 3/4 inch cutting height focuses the cut along the workpiece edge, which supports controlled passes on 1/2 inch, 1 inch, 1-1/2 inch, or 2 inch thick stock. A 1/2 inch shank provides a stout mounting in compatible routers, helping the bit track true when working heavier solid surface pieces. The 2-7/8 inch overall length suits typical router collet engagement while keeping the cutting action close to the tool for stability.
This round under router bit uses a 1/2 inch shank, which fits routers equipped with a matching 1/2 inch collet for solid grip during bullnose cutting. The solid surface round under design works together with separate corner rounding bits, so the combination produces a full 180 degree bullnose on 1/2 inch, 1 inch, 1-1/2 inch, or 2 inch thick stock without turning the material over. That workflow keeps heavy laminated workpieces, such as two 30 inch by 98 inch by 1/2 inch sheets weighing about 200 pounds, in one position while edges are shaped. The furnished Ultra-Glide non-marring Delrin sleeved ball bearing guide rides the work surface, which guides the bit along the edge while helping protect finished faces from marking during routing.
The Amana Tool 57138 solid surface round under router bit is specified for use with corner rounding bits, so together they cut a full 180 degree bullnose profile on solid surface stock in 1/2 inch, 1 inch, 1-1/2 inch, or 2 inch thicknesses. That capability is useful on laminated assemblies such as countertops built from two 30 inch by 98 inch by 1/2 inch sheets, which can weigh about 200 pounds and are impractical to flip during fabrication. The solid surface round under cutting geometry allows the operator to work from one side only, which supports safer handling of large panels and consistent edge alignment. The bit is also described as useful for onsite cutting where a conventional round-over cannot be used, so it supports field modifications or installations where shop-style setups are not available but the same 180 degree bullnose edge is desired.
The 2-1/8 inch diameter cutting head and 1/2 inch radius shape work together to form the full bullnose curve, which helps produced edges match standard solid surface profiles across different jobs. A 3/4 inch cutting height defines the depth of engagement along the edge, which supports consistent results when repeating the same pass on multiple pieces or along long runs. The 1/2 inch shank connects this 2-flute bit securely to routers with a 1/2 inch collet, which supports smoother tracking during continuous cuts on thick or laminated solid surface material. The Ultra-Glide non-marring Delrin sleeved ball bearing guide rides the work surface as the bit cuts, which helps keep the profile aligned while protecting visible faces from contact marks during routing and finishing.
The Amana Tool 57138 router bit, used with corner rounding bits, cuts a full 180 degree bullnose on 1/2 inch, 1 inch, 1-1/2 inch, or 2 inch thick solid surface stock for a rounded front edge.
The Ultra-Glide non-marring Delrin sleeved ball bearing guide rides the work surface and helps steer the bit, which protects the solid surface face while guiding the bullnose cut.
This solid surface router bit has a 1/2 inch shank, so it mounts in routers that accept a 1/2 inch collet for secure holding during bullnose and round under cuts.
The router bit is described as useful for onsite cutting where a conventional round-over cannot be used, so it supports field modifications while still producing a full bullnose profile.
This round under router bit is specified for 1/2 inch, 1 inch, 1-1/2 inch, or 2 inch thick solid surface stock, giving coverage for common countertop and edge build-up configurations.
The cutting head has a 2-1/8 inch diameter, a 1/2 inch radius, and a 3/4 inch cutting height, which together shape a full bullnose curve along the solid surface edge.
The Amana Tool solid surface round under router bit, model 57138, combines a 2-1/8 inch diameter, 1/2 inch radius, and 3/4 inch cutting height to produce a 180 degree bullnose on 1/2 inch to 2 inch thick stock. Its 1/2 inch shank and 2-flute design support steady routing on large laminated sheets, such as two 30 inch by 98 inch by 1/2 inch solid surface panels. The Ultra-Glide non-marring Delrin sleeved ball bearing guide helps protect finished faces while guiding the edge profile. For solid surface projects requiring a consistent bullnose edge without turning heavy workpieces, this router bit provides the geometry and guidance features described.
