发明名称 CUTTING TOOL UNIT
摘要 PROBLEM TO BE SOLVED: To provide a cutting tool unit having the angle adjusting mechanism which is effectively usable in the whole length of a cutting edge of a tip, and has a simple structure, the cutting tool suitable when a workpiece such as a semiconductor is comparatively small. SOLUTION: This cutting tool unit is provided with: a shank 51 fixed to a frame 36 of a cutting unit; and a cutting tool 61 mounted to be attachable/detachable to/from the shank 51 by a screw 67 substantially parallel to a rotating direction of the frame 36 and oscillatable by making the screw 67 as an oscillation shaft. A projecting part 64 is formed at one end part of the cutting tool 61 with the tip 62 at the other end part thereof fixed. A plurality of recessed parts 54 to which the projecting part 64 is engaged according to an oscillation angle are formed on the shank 51. By recess-projection engagement of the projecting part 64 on the cutting tool 61 side and a recessed part on the shank 51 side, a contact part of the cutting edge of the tip 62 with the workpiece is changed by adjusting a mounting angle of the cutting tool 61.
