Cylinder Round Dental Burs

Cylinder round dental burs are rotary instruments with a straight-sided cylindrical head and a rounded tip, used for flat axial walls and a smooth internal line angle in crown, bridge and cavity preparation. This collection holds the Busch diamond cylinder round figures (838, 880, 881, 882, 886 and their 5xxx/6xxx/8xxx super coarse, coarse and fine grits), Ziramant cylinder round burs for zirconia (6880Z, 6838LZ, 8838LZ), carbide crown cutters (23RX, 34, 36RDL) and carbide cylinder round laboratory cutters (426 series), made in Germany on FG, RA and HP shanks.

The rounded tip resists gouging the pulpal floor while the cylindrical body keeps preparation walls parallel — a combination that makes this shape a staple for full-coverage crown reduction, Class I cavity walls, and controlled margin refinement.

Which Cylinder Round Bur Do You Need?

Choose by material and shank first — FG diamonds and carbide crown cutters for chairside preparation, HP diamonds and carbide cutters for the laboratory — then by head size and, for diamonds, grit (the ring color in each row). Busch codes grit with the first digit: 5xxx super coarse, 6xxx coarse, 8xxx fine, and the plain figure is medium.

Clinical Use

Chairside, the cylinder round shape is a staple for full-coverage crown reduction, parallel Class I cavity walls and axial wall refinement: the rounded tip avoids gouging the pulpal floor and internal line angles while the straight sides keep walls parallel, and the crown cutters section old crowns for removal. In the laboratory the HP versions trim and shape acrylics and model materials. Match the grit to the step — coarse for reduction, medium for shaping, fine for margins — and run each instrument at the speed recommended for its shank; see our Dental Bur Speed Chart.

Care and Reconditioning

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

FAQ

What is a cylinder round bur used for? Crown and bridge reduction, parallel cavity walls, and axial wall refinement — the rounded tip avoids gouging internal angles while the straight sides keep preparation walls parallel.

Which grits and shanks are available? Carbide crosscut and diamond grits from super coarse (black) reduction through extra fine (yellow) polish, in FG, RA, and HP shank lengths.

Where are these burs made? Every instrument in this collection is manufactured by Busch & Co. in Engelskirchen, Germany — an ISO 13485-certified specialist in rotary precision instruments since 1905 — and ships fast from our US warehouse.
