Busch 447AU Pave Cut Carbide Twist Drill Round Burs On 3/32" Shanks

Pavé setters reach for this bur when the pilot hole and the stone seat need to be cut in a single pass at the bench. The Busch 447AU Pavé Cut Carbide Bur is a dual-action tool that combines a twist drill and a round bur in one instrument, so pre-drilling and shaping happen together instead of as two separate operations. The result is cleaner seats, better alignment, and less time spent changing tools.

Notes

Consolidating the drilling and shaping steps into one operation helps keep seats consistent and reduces tool changes during pavé work. Sizes run 0.80–1.60mm, all on 3/32" shanks.
