The bur has a ball shape with a radius end, also known as shape D, which is suitable for machining curved surfaces and for enlarging holes. Carbide provides good wear resistance and maintains sharp edges longer than high-speed steel (HSS). With no coating or surface treatment, uncoated carbide supports a range of general-purpose applications. In most applications, burs should be operated within the recommended cutting speed range, expressed in surface feet per minute (SFPM).
Carbide Burrs Can be Used on Many Materials
Tungsten Carbide burrs can be used on most hard materials: metals including steel, aluminum and cast iron, all types of stone, ceramic, porcelain, hard wood, acrylics, fiberglass and reinforced plastics. When used on soft metals such as gold, platinum and silver carbide burrs are ideal as they will last a long time with no chipping or breaking.
