Choosing a Grit
Busch marks grit with a colored ring and a prefix on the figure number, so you can order the exact 837LKR you need:
- Medium (standard): Busch No. 837LKR for everyday preparation
- Fine (red ring): Busch No. 8837LKR 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).
- 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
- Long axial walls: the longer working head reaches the full height of tall clinical crowns.
- Rounded shoulder: a shoulder finish line with a rounded internal angle for all-ceramic and zirconia crowns.
- Parallel preparation: consistent axial walls with fewer passes.
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.
