Round Dental Burs | Rosehead Shape

Round dental burs — the rosehead shape — are the omnidirectional cutters for caries excavation, access opening, and retention grooves.

This collection spans Busch tungsten carbide (figure 1, 1S, and the low-vibration 1SX and slim-neck 1SXM cuts), diamond (the 801 family in super coarse to extra fine ring-coded grits, Cool-Diamant, MicroPrep, and ZIRAMANT), and steel rounds in US numbers ¼ through 10 across FG, RA, and HP shanks, plus the laboratory round cutters and abrasive stones.

Every bur on this page is a genuine Busch instrument and ships from our US warehouse.

The spherical head cuts in every direction, making the round bur the most versatile instrument on the bracket table — from opening a pit-and-fissure lesion to refining an endodontic access. Busch’s precision grinding delivers the concentricity that keeps small round burs chatter-free at speed.

Clinical Use

Carbide rounds excavate caries and open access cavities at low speed on the RA shank (1SX for less vibration, 1SXM to reach deep, narrow lesions) and cut retention features at high speed on FG; diamond rounds in coarse to extra-fine grits open enamel, refine endodontic access, and finish; the 41 finishing rounds smooth composite and amalgam; steel rounds and the 421/71/81 round cutters trim acrylic, plaster, and alloy in the laboratory; and the green and pink abrasive stones grind and smooth where a bur would chatter.

Care and Reconditioning

Carbide, steel, and diamond rounds are cleaned, disinfected, and sterilized between patients in a bur block; steel burs must be dried promptly to prevent corrosion, and any bur with dulled grit or a chipped blade is discarded. Our Dental Bur Reprocessing & Sterilization Guide covers the full workflow for Busch rotary instruments.
