Choosing a Grit

Busch marks grit with a colored ring and a prefix on the figure number, so you can order the exact 854R you need:

• Coarse (green ring): Busch No. 6854R for rapid reduction
• Medium (standard): Busch No. 854R for everyday preparation
• Fine (red ring): Busch No. 8854R for refining margins and surfaces

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)

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 854R is used for the following steps:

• Laboratory grinding: large HP heads for contouring ceramic, composite and acrylic in the straight handpiece.
• Adjustment: trimming crowns, bridges and denture components with a rounded profile.
• Smooth contours: blending rounded transitions on restorations.

Care and Reconditioning

Clean, disinfect and sterilize the instruments between uses following the manufacturer instructions and the symbols on each package, and replace an instrument 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.
