About the FG4 round bur

The FG4 is the ISO No. 4 round tungsten carbide bur (1.4 mm head) — one of the most reordered burs in dentistry. On a high-speed handpiece it opens carious lesions and gains endodontic access; the round head is also the standard choice for removing old restorations and creating retention grooves. Sizes run from the fine No. 2 up to No. 8; the No. 4 sits in the middle as the everyday workhorse. Supplied factory-direct in clinic-pack quantities with CE & ISO certification.
