Which wheel is primarily used to create the bevel on the lens edge during edging?

Explanation:
The bevel wheel is the one designed to cut and define the angled edge around the lens. This bevel creates a narrow, sloped edge that lets the lens seat properly in the frame groove and helps prevent chipping or stresses at the edge. After beveling, the edge is usually finished and polished to smoothness with a polishing wheel. Other wheels perform deburring, smoothing, or minor refinishing tasks and do not establish the bevel geometry in the same way, so they aren’t used to create the bevel itself.
