Latch type burs – also known as RA burs, these dental burs are made to use with low-speed contra-angle handpieces.
Dental burs are used for cutting hard tissues – tooth or bone. They are made of steel, stainless steel, tungsten carbide and diamond grit. There can be a bewildering range of dental burs in any dental catalogue, but for basic veterinary use only a few burs are needed. All burs have a shank and a head.
