US No. 7404 Bur – Busch Finishing Football (Egg) Carbide, Made in Germany
The US No. 7404 is the American number for an egg (football) finishing bur with a 1.4 mm head (ISO size 014): a multi-bladed oval head that follows occlusal anatomy and smooths rather than cuts, for contouring and finishing composite. Busch & Co. manufactures it in Germany as Busch No. 44E 014. Every US No. 7404 on this page is a genuine Busch instrument and ships from our US warehouse.

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.
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
- Occlusal contouring: shaping cusp inclines and fossae in posterior composite without flattening the anatomy.
- Lingual finishing: refining the concave lingual surfaces of anterior restorations.
- Pre-polish: leaving a smooth surface ready for a two-step polisher.
At 1.4 mm the No. 7404 is the smallest of the egg finishers, suited to tight occlusal anatomy and premolars. Step up to the No. 7406 (1.8 mm) or No. 7408 (2.3 mm) for broader 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.
