US No. 7007 Bur – Busch Finishing Round Steel, Made in Germany

The US No. 7007 is the American number for a round finishing bur with a 2.1 mm head (ISO size 021): a round head with many fine blades that smooth rather than cut, for finishing acrylic and removing tool marks. Busch & Co. manufactures it in Germany as Busch No. 41 021 in steel for the straight handpiece. Every US No. 7007 on this page is a genuine Busch instrument and ships from our US warehouse.
