Prima® Classic Diamond Burs are manufactured from the highest quality steel shanks and natural diamond grit, to international specifications. This advanced manufacturing, using computer controlled precision engineering, ensures true concentricity and balance, minimising vibration and potential damage to hand piece bearings. The Diamond plating of a Prima® Classic bur is carried out under strictly controlled conditions specific to the bur pattern involved. This process gives the highest strength and even distribution of diamond, resulting in a concentric, balanced bur with long lasting cutting ability.
