Fabricate Custom Solid Surface Drainboards with Professional Precision

Create functional and elegant drainboards in your solid surface countertops with the Freud 85-052 Drainboard Router Bit. Designed specifically for the unique demands of materials like Corian®, Avonite®, and other composites, this bit allows you to route gently sloping grooves that direct water back into the sink. The 1/8-inch radius produces a smooth, rounded groove bottom that is easy to clean and aesthetically pleasing, adding a high-end custom touch to any kitchen installation.

Engineered for flawless performance, this bit features Freud's specialized TiCo™ Hi-Density Carbide, formulated to withstand the abrasive nature of solid surface materials without dulling prematurely.

This feature ensures that the bit follows your template or jig without leaving scratches, burn marks, or indentations on the finished countertop surface. Whether you are a professional fabricator or a serious DIYer, this tool provides the control and finish quality needed for superior results using hand-held portable routers.
