A dental diamond bur with a flat end taper and fine grit is commonly used in dentistry for precision shaping, smoothing, and contouring of tooth enamel and dental materials. Its flat end and taper design make it suitable for creating smooth, flat surfaces and achieving detailed, intricate work. The fine grit ensures a controlled and refined material removal process, making it ideal for procedures like cavity preparation, margin refinement, or cosmetic dentistry work, where precision and aesthetics are crucial.
