| Busch figure | Pattern | Sizes by shank |

Steel crosscut — figure 38 (US 698–706 and unnumbered sizes), HP1 items
Clinical Use
Plain-cut figure 23 tapers leave smoother, convergent walls for amalgam and crown preparations; crosscut figure 33 carbides cut faster and cooler and are the choice for crown sectioning and bulk preparation, with the US 700 and 701 as the standard sizes; and the figure 38 steel crosscuts on the HP shank are the low-speed straight-handpiece option in the same US sizes plus the unnumbered 0.5–3.1 mm heads.
Care and Reconditioning
Carbide and steel tapered fissure burs are cleaned, disinfected, and sterilized between patients in a bur block; steel burs must be dried promptly to prevent corrosion, and any bur with a chipped blade or a bent shank is discarded. Our Dental Bur Reprocessing & Sterilization Guide covers the full workflow for Busch rotary instruments.

What is the difference between 170 and 700 series?
