Under Mount Bowl Round Over Bit For Finished Edges

under mount bowl round over bit from Amana Tool is a solid surface router bit designed to create decorative, finished edges for undermount type bowls. The 2-1/8 inch diameter cutting profile shapes a broad, smooth transition around sink and bowl cutouts, which helps produce a professional-looking edge on solid surface countertops. A 1/2 inch cut depth works the material closely around the bowl rim, controlling how much solid surface is removed so the edge stays strong while still easing the transition. The 1/2 inch radius built into the profile defines how soft the round over feels by hand, which matters when finishing exposed bowl edges for everyday use. An 18 degree angle in the profile further refines the geometry of the edge, which helps installers match decorative details across multiple undermount bowls in a project.

Key Router Bit Details That Support Bowl Work

• The 1/2 inch shank fits routers that accept 1/2 inch bits, which supports a solid grip in the collet for reduced chatter while cutting solid surface edges around bowls.
• The 1 inch cutting height gives vertical coverage along the bowl edge, which allows the bit to address both the top transition and the side wall of the solid surface in a single routing pass when conditions allow.
• The 3 inch overall length provides reach from the router base to the cutting edge, which helps when working over countertop surfaces while routing around sink openings.
• The 3/4 inch B1 dimension defines part of the working profile, which guides how the bit engages the material and helps installers predict the resulting reveal at the bowl interface.
• The solid surface routing design supports use on Corian sink and bowl numbers 802S, 804S, 805S, 809S, 810S, and 871S, which gives installers a defined option when edging those specific undermount units.
• The 2-flute configuration creates the cutting action for the profile, which affects chip evacuation and contributes to the surface finish left on the solid surface edge around the bowl.

Router Bit Geometry For Controlled Edge Passes

The 2-1/8 inch diameter on this Amana Tool router bit engages a wide section of solid surface, which lets installers shape the entire round over zone at the undermount bowl in fewer passes. A 1/2 inch cut depth limits how far the bit enters the material, which aids in controlling the edge profile and reduces the risk of over-removing material at the bowl joint. The 1 inch cutting height spans the vertical edge, which helps align the decorative round over with the sink opening cut. The 18 degree angle and 1/2 inch radius define the final contour, which allows repeatable results from bowl to bowl when using the same sink models. The 1/2 inch shank matches routers built for heavier bits, which supports stable operation during longer edge runs.

Undermount Bowl Edge Profiles In Solid Surface

This Amana Tool under mount bowl round over bit is designed for undermount application in solid surface work, which focuses it on shaping the visible transition around sink and bowl cutouts. The bit is specified for decorative, finished edges on undermount type bowls, which lets fabricators standardize an attractive edge form wherever a compatible bowl is installed. In solid surface jobs using Corian sinks or bowls, this router bit can be used for Corian sink and bowl numbers 802S, 804S, 805S, 809S, 810S, and 871S, which ties the profile directly to known bowl geometries in that product line. Matching the bit to these numbered bowls allows the installer to build a repeatable routine for cutting and finishing the undermount opening, which supports consistent results across multiple countertops within the same project.

Profile Details That Support Repeatable Results

The 2-1/8 inch diameter and 1/2 inch radius define how this roundover bit wraps the edge, which helps installers anticipate how much material will be shaped with each pass along the bowl perimeter. A 1/2 inch cut depth and 1 inch cutting height combine to control both horizontal and vertical engagement, which supports predictable edge geometry when routing around the full sink opening. The 18 degree angle within the profile outfits the bit with a specific contour, which is important when matching an established design standard or reproducing a previously delivered countertop edge around similar undermount bowls. With a 1/2 inch shank carrying a 3 inch overall length, the bit brings sufficient rigidity and reach, which assists in maintaining a steady cut as the router travels over the countertop surface during bowl cutout finishing.
