A tool support base and a tool post for cutting a casting, in which contact surfaces in sliding contact with both side plates are formed on both sides of the tool support base and the tool post. A cut recess is formed in the sliding contact surface so as to vertically extend in the surface. Deposit welding is applied to the cut recess and a ridge of weld deposit generally flush with the contact surface is formed by grinding means that makes the weld deposit, formed by the deposit welding, flush with the contact surface. The construction minimizes wear of the contact surface as much as possible, and even if particles of casting waste materials enter gaps between the tool support base and the tool post and the side plates, the construction can avoid wear by such particles.
