Drilling a clean pilot hole for a stone seat, a rivet, or a jump ring starts with a twist drill sized to the job. Busch Fig 77 tungsten vanadium steel twist drills come in 19 sizes from 0.50mm to 2.30mm, manufactured to ultra-high precision tolerances for consistent, accurate performance across a wide range of drilling work. Each drill is mounted on a 3/32" (2.35mm) shank for fast, tool-free changes in standard flex-shaft handpieces and drill presses.
