These grinders are used for grinding round and hollow jobs whether the internal surface of this job is completely round, ditched round, or is in taper. Small grinding wheels of 3 cm to 5 cm, are used in such grinders. Sometimes grinding wheels of special shape 0.2 cm to 0.3 cm. These grinders can be divided into two parts. a. Chucking Grinder
