Darby Single Use Carbide Burs are designed, manufactured, and finished for optimum strength and performance. The burs are brazed at the neck as opposed to the base of the head, delivering optimum concentricity and strength. Our burs are engineered to cut more effectively with greater blade contact on the tooth surface and reduce the risk of chipping or breakage. The design ensures a fast, smooth, vibration-free performance, reducing patient discomfort as well as operating time.
