US No. 958 Bur – Busch End Cutting Cylinder Carbide, Made in Germany
The US No. 958 is the American number for a end-cutting bur with a 1.2 mm head (ISO size 012): a cylinder with cutting blades on the end face only, so it refines a shoulder or floor without touching the axial walls. Busch & Co. manufactures it in Germany as Busch No. 207 012. Every US No. 958 on this page is a genuine Busch instrument and ships from our US warehouse.

Speed and Technique
Hold the bur parallel to the axial wall and apply pressure only along the long axis; the smooth sides will not cut, which is the safety feature of the design. Maximum recommended speeds for every Busch shape are in our Dental Bur Speed Chart, and reprocessing steps in the Bur Sterilization Guide.
Made in Germany by Busch & Co.
Busch & Co. has manufactured rotary instruments in Engelskirchen, Germany since 1905. Every instrument on this page is a genuine Busch product, precision-ground on a concentric shank under ISO 13485-certified quality management and covered by our Busch warranty.
Clinical Use
- Shoulder finish lines: squaring and smoothing the shoulder of a crown preparation with the axial wall already established.
- Gingival floors: flattening the gingival floor of a proximal box without widening it.
- Margin correction: lowering a finish line by a controlled amount.
At 1.2 mm the No. 958 is an end diameter matched to shoulder widths.
Care and Reconditioning
Busch carbide burs are reusable: clean, disinfect and sterilize them between patients following the manufacturer instructions and replace them once they dull. Our Dental Bur Reprocessing & Sterilization Guide gives the steps for Busch rotary instruments.
