Darby Dental Supply carbide burs are designed, manufactured and finished for optimum strength, performance and durability. An important element of every bur is the brazing technique. The burs are brazed in the neck as opposed to the base of the head, as found in many competitive products. Our 100% carbide neck delivers optimum concentricity and strength. Engineered to cut more effectively, with greater blade contact on the tooth surface and reduced risk of chipping or breakage. The design ensures a fast, smooth, vibration-free performance, reducing patient discomfort as well as operating time.
