Thus, the quality and life compared to the positively coated drills could be significantly improved. In addition, these diamond drills are ground between points. This manufacturing process of grinding ensures less wear with high concentricity. We can supply our diamond drills in various designs such as pick-up, wall thickness, drilling depth, grain size etc.
