Drester tools ovt.Ltd. Manufactures electroplated diamond and cubic boron nitride [cbn] mounted points [grinding pins] for incorporating automatic process control and unique plating technology. The pins are made up of selected grades of blocky natural or synthetic diamond and cbn to ensure smooth free cutting action with minimal heat build-up and long service life. The unique plating process of these electroplated diamond and cubic boron nitride [cbn] mounted points provides high bond strength, which reduces the risk of premature pull-out of the diamond / cbn abrasive grains. The blanks are made of medium carbon steel to minimize bending of the shank during use which is more tough than ordinary mild steel. The pins can also be used for external and internal grinding of a wide variety of materials such as fibre-glass, bakelite, carbides, ferrites, graphite, ceramics, glass etc.. Cbn pins are applicable for high speed , tool and die steels, cast irons, hardened steels [45rc and up] and are available in a range of 1 mm to 30 mm diameter in a standard size.
