Choosing a Grit

Busch marks grit with a colored ring and a prefix on the figure number, so you can order the exact 835 you need:

• Coarse (green ring): Busch No. 6835 for rapid reduction
• Medium (standard): Busch No. 835 for everyday preparation
• Fine (red ring): Busch No. 8835 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)
• 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, and is covered by our Busch warranty.

Clinical Use

• Shoulder margins: creating butt-joint shoulder margins for crowns and onlays.
• Axial reduction: parallel axial walls with a flat floor for retention form.
• Occlusal and inlay preparation: flat floors and walls for inlays, onlays and box forms.

Care and Reconditioning

Busch rotary instruments are reusable: clean, disinfect and sterilize them between patients according to the manufacturer’s instructions, and replace a bur once it dulls or shows damage. Our Dental Bur Reprocessing & Sterilization Guide walks through the workflow for carbide, diamond and steel instruments.
