USAGE: Smooth Routed Bottoms in Plastic & Aluminum
This tool is similar in design to the Onsrud 52-000 series, however the corners have a slight radius. This radius is designed to give a smoother bottom surface when hogging out large areas. Sharp tips will leave a slightly deeper cut on one side leaving the appearance of scratches. The rounded corners of this series don't leave harsh lines, making surfaces optically much smoother.
