One box that covers the everyday cutting at the bench: pilot holes, cavity and seat shaping, prong notching, stone seat preparation and detail cleanup. This curated 28-piece kit brings together Busch micro burs and high speed steel twist drills, all on 3/32" shanks, so nothing in it needs a different handpiece.
The set spans ball burs, hart 90 degree burs, setting burs and twist drills across a practical size range, and everything stores in the included 48-hole plastic bur box for quick access and safe keeping between jobs.
Every bur and drill in the kit is on a 3/32" shank, so the set fits 3/32" shank handpieces and flex shafts.
Everything in the box.
