Abstract

An insert attached to a tool body of a hole machining tool having an attachment seat and a pressing member for pressing the insert to adjust the position of a peripheral cutting edge in a diameter direction of the tool. The insert has a panel shape. One surface of the insert in a thickness direction provides a seating surface, the other surface in the thickness direction provides a peripheral flank surface. A surface facing the rear side of the insert in a tool rotation direction provides a pressed surface in a state that the insert is attached to the attachment seat. A side surface facing the front side in the tool rotation direction provides an inclined surface, and a peripheral cutting edge is formed at a ridge portion outside of the inclined surface in the diameter direction of the tool.

Claims8

Dependent claims

An insert attached to a hole machining tool having a tool body rotating about an axis line, comprising;

a recessed portion that is formed to be open at a front end of the tool body and open to the outside in a diameter direction of the tool body;
an attachment seat that is formed on a rear side of the recessed portion in a tool rotation direction;
and
a pressing member for pressing a pressed surface of the insert to adjust a position of a peripheral cutting edge in the diameter direction of the tool body, the pressing member being disposed on the rear side of the attachment seat in the tool rotation direction,
wherein one surface in the thickness direction of the insert having a panel shape forms a seating surface which is seated on a wall surface of an attachment seat of the tool, facing outwardly in the diameter direction of the tool body and disposed in the tool body, and the other surface in the thickness direction becomes a peripheral flank surface facing outwardly in the diameter direction of the tool body,
wherein a surface of the insert facing a rear side in the tool rotation direction forms a pressed surface in a state in which the insert is attached to the attachment seat, a side surface of the insert facing the front side in the tool rotation direction forms an inclined surface, and a peripheral cutting edge is formed at a ridge portion of an inclined surface facing outside in the diameter direction of the tool body, and
wherein the pressed surface intersects the seating surface at an obtuse angle.
