Speed and Technique
Steel wheels are laboratory instruments for the straight handpiece: keep the speed moderate, present the edge squarely, and do not use them on enamel or metal. 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
- Grooves and slots: cutting retention channels, guide grooves and slots in acrylic, wax and plaster.
- Relief and trimming: reducing flat areas and thinning material in denture bases and models.
- Separation: parting and sectioning in laboratory work where a narrow kerf is wanted.
At 0.8 mm the No. 12 is a wheel sized for laboratory cutting and grooving.
Care and Reconditioning
Busch steel 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.
