How to select the right carbide bur for metal finishing?

Select a carbide bur based on material hardness, desired finish, and cut type. For fast stock removal on steel, a single-cut flame bur like the WIDIA M40448 (SH-2) works well. For softer metals, a double-cut bur reduces clogging. Always match shank size to your rotary tool's collet.
