Abstract

The present invention provides a grinding member for connection to a drive connection member to form a grinding cup for grinding the hard metal inserts or working tips of drill bits (percussive or rotary), tunnel boring machine cutters (TBM) and raised bore machine cutters (RBM) to restore them to substantially their original profile, said grinding member having: (a) a grinding section having top and bottom surfaces, a centrally disposed convex recess formed in the bottom surface of said grinding section having the desired profile to be ground; (b) a support section adjacent the top surface of said grinding section; (c) means to connect the grinding member to the drive connection member wherein the grinding member can be disconnected from the drive connection member when it becomes worn.
