CUTTING EDGE REPLACEABLE GROOVING TOOL

摘要

PROBLEM TO BE SOLVED: To provide a cutting edge replaceable grooving tool capable of improving machining accuracy by sufficiently securing the rigidity of a tip part of a tool body without increasing the number of parts. SOLUTION: The cutting edge replaceable grooving tool 30 includes a cutting insert 20 having a blade and the tool body 1 having a shaft shape and allowing the cutting insert 20 to be detachably mounted on the tip part 3. The protruding direction of the tip part 3 of the tool body 1 is made to be a protruding direction X. A slit 37 opened on a tip surface 3E directed at least in the protruding direction X and communicating with an insert mount seat 4 for mounting the cutting insert 20 is formed at the tip part 3. The slit 37 has a first wall surface 37A directed in the protruding direction X and a second wall surface 37D intersecting the first wall surface 37A to be continuous therewith.
