RA (latch, 2.35 mm shank, contra-angle). See the Busch Bur Size Chart for head and shank dimensions.
Speed and Technique
Finishing burs work at reduced pressure: use the RA carbide version with water spray in the contra-angle and let the blade count produce the surface; heavy pressure only dulls them. 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
-
Composite and amalgam finishing: smoothing occlusal and marginal areas after contouring without gouging.
-
Margin refinement: blending restoration margins into tooth structure.
At 2.7 mm the No. 7009 is a large finishing head for broad surfaces.
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.
