The portable valve seat grinder also comprises a shaft, to one end of which is securely attached a grinding element. The shaft with attached grinding element is mounted in the body element by sliding the shaft into the bushings such that the grinding element is positioned near the screw threads on the body element. The outer surface of the body element can be knurled to aid with handling during use.
