A ball bur is the bench workhorse for opening a hole, cutting a seat, and removing metal in a controlled, rounded cut. Busch Fig. 1 Ball Burs come in 35 sizes from 0.25 mm to 3.70 mm, machined in tungsten vanadium steel to ultra-precise tolerances for clean, repeatable cutting across metalsmithing and jewelry fabrication. Each size is sold in a pack of 6, so the sizes you reach for most stay stocked.

- Ultra-precise tolerances for repeatable results across every bur in the pack
- Size range of 0.25 mm–3.70 mm covers fine detail work through larger seat cutting
