Choosing a Grit

Busch marks grit with a colored ring and a prefix on the figure number, so you can order the exact 863 you need:

• Super Coarse (black ring): Busch No. 5863 for fast bulk removal
• Coarse (green ring): Busch No. 6863 for rapid reduction
• Medium (standard): Busch No. 863 for everyday preparation
• Fine (red ring): Busch No. 8863 for refining margins and surfaces
• Extra Fine (yellow ring): Busch No. 863EF for final finishing and polishing preparation

Sizes and Shanks

The three-digit size code is the head diameter in tenths of a millimeter (for example, 012 = 1.2 mm).

• HP (2.35 mm shank for the straight handpiece)
• FG (friction grip, 1.6 mm shank for the high-speed handpiece)

See the Busch Bur Size Chart for full dimensions and the Dental Bur Speed Chart for maximum recommended speeds.

Made in Germany by Busch & Co.

Busch & Co. has manufactured rotary instruments in Engelskirchen, Germany since 1905. Each diamond is produced under ISO 13485-certified quality management on a concentric shank for smooth, chatter-free cutting. Every Busch instrument is covered by our Busch warranty.

Clinical Use

The FG 863 flames are used chairside for interproximal finishing, margin refinement and contouring (see the list below); the HP versions (titled "Cylinder Pointed" on their product pages) fit the straight handpiece for laboratory work and chairside adjustments.

• Interproximal finishing: reaching proximal areas and embrasures with a slender, pointed profile.
• Margin finishing: refining subgingival and feather-edge finish lines.
• Contouring: shaping composite restorations and veneer preparations.

Care and Reconditioning

Clean, disinfect and sterilize the instruments between uses following the manufacturer instructions and the symbols on each package, and replace a diamond once it loses cutting performance or shows damage. Our Dental Bur Reprocessing & Sterilization Guide covers the workflow for Busch rotary instruments; maximum speeds are in the Dental Bur Speed Chart.
