Solid surface repair bits are used to remove damaged areas of engineered countertop surfaces such as Corian and Avonite, cutting a clean plug opening that can be filled with a matching material for a nearly invisible repair. Most bits in this category are carbide-tipped or solid carbide to ensure longevity and clean cuts on durable synthetic surfaces. Plug sizes typically range up to 1-3/4" in diameter to accommodate the most common repair needs. These bits are suitable for use with handheld routers or CNC machines, making them a practical addition to any fabrication or installation shop looking to extend the life and appearance of solid surface installations.
