2-25/32" x 1/2" Radius Corner Rounding Bit with ball Bearing Guide, 2-Flute, 1/2" Shank

2-25/32 x 1/2 Radius Corner Rounding Bit For Solid Surface

2-25/32 x 1/2 Radius Corner Rounding Bit describes an Amana Tool router bit built for solid surface countertop work, so installers can shape sink edges with consistent geometry. The bit combines a 2-25/32 inch overall length with a 1/2 inch shank, giving solid support in 1/2 inch collet routers during undermount profiling. A 33/64 inch radius cutting edge forms a controlled round-over on solid surface, which helps produce a comfortable, uniform transition at the sink opening. The bit diameter of 2-9/64 inch and 63/64 inch cutting height work together to remove material efficiently around sink cutouts, which matters when trimming full-depth tops. As a router bit in the solid surface category, it fits directly into workflows for fabricating Gemstone, Livingstone, Du br Pont, Wilsonart, and Formica sink and vanity installations listed by the manufacturer.

Key Router Bit Details That Support Sink Work

• The 10 degree cutting draft works with a matching bearing so the cutter maintains the correct angle along the sink edge, which helps keep the profile repeatable around the entire bowl opening.
• The ball bearing guide lets the bit follow the sink or template edge as it trims and profiles, which reduces layout time and helps keep the cut consistent on curved undermount shapes.
• The 2-flute design provides a balanced cutting action, which supports a smoother finish on solid surface sheet when profiling the countertop after the bowl is mounted.
• The 1/2 inch shank offers a robust grip in the router collet, which supports stability when running a 2-9/64 inch diameter bit on deep sink reveals.
• The listed replacement bearing 4778 allows the guided system to be restored to proper function, which helps keep edge-following accuracy over the life of the bit.

Solid Surface Bit Geometry For Accurate Installation

The 10 degree angle on this corner rounding bit sets the cutting draft, so the bit shapes the reveal to match the intended undermount profile. That matters when trimming and profiling countertop edges after the bowl is mounted, because the angle needs to follow the sink wall. The 63/64 inch cutting height controls how much vertical edge can be cut in one pass, which helps match the full height of many solid surface sink reveals. With the 25/32 inch B1 measurement working with the main cutting height, installers can engage enough flute length to complete the profile at the sink perimeter while maintaining bearing contact.

Using This Router Bit In Solid Surface Sink Fabrication

Where This Corner Rounding Bit Is Applied

This Amana Tool router bit is designed specifically for undermount installations of multiple Gemstone vanity models, including 1514-VO, 1812-VO, 1613-VSO, 1814-VO, 1814-EVO, 1313-VO, 1513-VO, and 1711-VO. That targeted design continues with Gemstone bar and kitchen sink models such as 1014-S, 1016-S, 1318-S, 1411-S, 1507-S, 1515-S, 1815-S, 1524-S, 1517-S, 1616-S, N1616-S, 1616-ES, 2116-US, 2015-S, 2318-S, 2416-ES, 2615-S, 2716-US, 2718-S, 2818-S, 2033-S, 2916-UD, 1729-D, 2917-D, 1930-DL, 1630-D, 3016-D, 3118-D, and 3218-D. It is also specified for Livingstone vanity model K-140G and kitchen sink models K130-G, K140G, and K160G, aligning the bit geometry with those bowl profiles. The bit is listed for Du br Pont kitchen vanity models 810P, 8252, 8254, and 850P, as well as Du br Pont kitchen sink model 850-P, tying its draft and radius to these units. Wilsonart vanity models BV1514, BV1812, BV1313, and BV1711, plus Wilsonart kitchen sink models BK2015, BK1515, BD1630, BD3016, and BK2716US, are also named applications, connecting this router bit directly to those fabricator programs. Formica vanity model L080 and Formica kitchen sink models K080A and K250A are further specified uses, so shops working with these tops can match the sink reveal to manufacturer expectations.

Why The Bit Geometry Matters For Repeatable Results

The 10 degree cutting draft with a matching bearing enables the cutter to do more work, which reduces hand-finishing time along the sink reveal. By trimming and profiling the countertop edges after the bowl is mounted, the bit aligns the finished edge to the actual bowl position, which supports a tight, even joint. The 33/64 inch radius produces a consistent round-over that transitions from deck to bowl, which matters for both appearance and a uniform reveal on the listed Gemstone, Livingstone, Du br Pont, Wilsonart, and Formica models. The 2-9/64 inch diameter and 63/64 inch cutting height let the bit engage enough surface area to profile full-depth solid surface sinks in one controlled path, which can improve throughput on repetitive sink cutouts. With a 2-25/32 inch overall length and 25/32 inch B1 dimension, the geometry balances reach and rigidity, which helps the bit track the bearing smoothly without excessive flex.

Common Questions About This Solid Surface Router Bit

Select This Bit For Specified Undermount Sink Profiles

The Amana Tool 2-25/32 x 1/2 Radius Corner Rounding Bit with ball bearing guide is built around a 10 degree draft and 33/64 inch radius that match listed Gemstone, Livingstone, Du br Pont, Wilsonart, and Formica undermount models. For shops fabricating these solid surface vanities and sinks, this geometry supports trimming and profiling the countertop edges after the bowl is mounted so the finished reveal tracks the actual sink wall. When a 1/2 inch shank, guided 2-flute router bit with a defined radius and angle fits your listed installations, this model aligns directly with that work.
