Working Plastic Materials with Woodworking Tools
Because solid surface materials like Corian are really just plastic, they can generally be worked with woodworking tools. They do, however, require that you equip your tools with carbide blades and bits as they are usually about three times as dense as most hardwoods. Take your time: when routing a decorative edge, make several passes. To achieve a matte finish, start with 180 grit and work down to 400 grit, then buff with a green Scotchbrite pad.
