15-piece Busch micro bur and drill kit covering common bench tasks—from pilot holes to seat shaping and cleanup. Includes ball burs, knife-edge burs, wheel burs, and matched twist drills for precise, controlled material removal across a range of small-scale applications.
Features
- Combines four bur and drill types in one coordinated kit for everyday bench work
- Ball burs in three sizes for rounding and sizing seats gradually
- Knife-edge burs for V-grooves, reliefs, and crisp edge definition
- Wheel burs for flat surfaces, undercuts, and edge cleanup
- Matched twist drills in coordinating sizes for clean, centered pilot holes
- All tools mount on standard 3/32" shanks for use in most flex-shaft handpieces

Notes
- Step up sizes in small increments and allow the tool to cut with light pressure.
- Use bur lubricant or coolant to improve finish quality and extend tool life.
- Secure work firmly and keep tools perpendicular to the work surface to avoid tapered seats.
