Managing Heat Generation During High-Speed Bur Operations

When Solid Carbide Burs operate at high rotational speeds, they generate frictional heat at the interface between the cutting edges and the workpiece. This heat, if not properly controlled, can cause the surface to discolor, soften, or, in some cases, become structurally compromised. In the early stages of cutting, the contact area is relatively small, and the localized temperature can rise very quickly.
