Abstract

PURPOSE: A bite for a lathe is provided to prevent a main body from being relatively vibrated about a bag holder during a cutting process by compressively fixing the joint of the main body to the joint groove of the bag holder using a bolt and to lower the manufacturing costs by enabling the independent replacement of the main body. CONSTITUTION: A bite for a lathe includes a main body (10) mounted with an insert tip (11). The rear end of the main body is integrated with a joint part (13) to be tapered. The joint part is formed with a first bolt hole (15) to be vertical to the axial direction (X) of the joint part. The front end of a bag holder (20) is formed with a joint groove (21). A second bolt hole (23) is vertical to the axial direction of the joint groove. The joint part of the main body is inserted into the joint groove of the bag holder. The joint part of the main body is fixed to the joint groove of the bag holder using a bolt (30) which is inserted into the first and second bolt holes.
