US No. 7005 Bur – Busch Finishing Round Carbide & Steel, Made in Germany

The US No. 7005 is the American number for a round finishing bur with a 1.6 mm head (ISO size 016): a round head with many fine blades that smooth rather than cut, for finishing restorations and margins. Busch & Co. manufactures it in Germany as Busch No. 41 016. Every US No. 7005 on this page is a genuine Busch instrument and ships from our US warehouse.

Clinical Uses of the US No. 7005

Composite and amalgam finishing: smoothing occlusal and marginal areas after contouring without gouging.
Margin refinement: blending restoration margins into tooth structure.
Laboratory finishing: the steel HP versions smooth acrylic and remove tool marks in the straight handpiece.

At 1.6 mm the No. 7005 is a mid-size finishing head for occlusal and proximal surfaces.

Speed and Technique

Finishing burs work at reduced pressure: use them with water spray in the contra-angle or high-speed handpiece 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.
