Claims

[Scope of utility model registration request]

A cartridge having a cutting edge is attached to a tool body via a key member, and a concave-convex fit extends straight between the joint surfaces of the tool body and the key member and the joint surfaces of the key member and the cartridge. In the cutting tool in which joint portions are respectively formed, the key member is slidable relative to the tool body and the cartridge in a direction in which the concave-convex fitting portions formed between the tool body and the cartridge extend, respectively, and A concavo-convex fitting portion formed between the main body and the key member and a concave-convex fitting portion formed between the key member and the cartridge are formed in different directions. Cutting tools.
