Choosing a Grit

Busch marks grit with a colored ring and a prefix on the figure number, so you can order the exact 909 you need:

• Super Coarse (black ring): Busch No. 5909 for fast bulk removal
• Coarse (green ring): Busch No. 6909 for rapid reduction
• Medium (standard): Busch No. 909 for everyday 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, and is covered by our Busch warranty.

Clinical Use

• Depth orientation: cutting horizontal depth grooves before incisal and facial reduction.
• Incisal and occlusal reduction: controlled edge reduction with a thin, flat working profile.
• Contouring: lingual shaping in the clinic and, in the larger HP sizes, trimming and separating in the lab.

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.
