An objective of the present invention is to provide an insert in which a cutting edge is formed only between an upper surface and a side surface so as to obtain a sufficient inclination angle of the cutting edge in a limited thickness and to improve coupling with a tool holder. The insert according to the present invention is an insert in which a main cutting edge that has three or more corners along the circumference and is formed at a corner between the upper surface and a main side surface of the insert and a sub cutting edge that is formed at a corner between the upper surface and a sub side surface of the insert are successively located between the corners, the insert having a flat lower surface. The main cutting edge forms an inclination angle whose height gradually decreases toward the sub cutting edge. In the main side surface, a first main side surface in contact with the main cutting edge and a second main side surface in contact with the lower surface are successively formed with different clearance angles. In the sub side surface, a first sub side surface in contact with the sub cutting edge and a second sub side surface in contact with the lower surface are successively formed with different clearance angles.

PURPOSE: A device for fixing a tip of a beveler for weld-processing is provided to smoothly discharge a chip generated when beveling and to precisely cut the beveling surface. CONSTITUTION: A device for fixing a tip of a beveler for weld-processing comprises a cutter unit(10) and a tip unit(20). The cutter unit includes a plurality of fixing grooves(12), a fixed surface(13), and a latching surface(14). The fixing grooves are formed in a longitudinal direction to the external diameter of a circular cutter(11). The latching surface is formed to be perpendicular to the fixed surface. The tip unit fixes the tip(23) forming the inclined surface(22) to be narrow towards the center of upper and lower sides from both ends of the cutting surface(21).

PURPOSE: A cutter device for a plate chamfering machine capable of simultaneously chamfering both surfaces of a plate is provided to reduce chambering time by simultaneously chamfering the top and bottom of a weld tip of a weld material using upper and lower base cutters. CONSTITUTION: A cutter device for a plate chamfering machine capable of simultaneously chamfering both surfaces of a plate comprises a cutter rotatably installed in a drive shaft(1). The cutter comprises upper and lower base cutters(3,4) and cutting tips(14). The upper and lower base cutters are installed in the top and bottom of a guide roller(5). The upper base cutter cuts the upper peripheral part of a weld material(2), and the lower base cutter cuts the lower peripheral part. The cutting tips are installed in the end of the upper and lower base cutters to be inclined at a predetermined angle.

PURPOSE: An indexable ball nose end mill is provided to expand the life time of an insert and prevent the vibration of the insert with the stable installation. CONSTITUTION: An end mill(301) has one more elongated pockets on a cylindrical holder. The end mill is installed with indexable inserts(302) in circular and axial directions to correspond to the pocket in number. The indexable insert has a curved cutting edge(302b) formed by a cross line of an upper curved surface and side clearance surface(302c). The clearance surface is inclined to the lower end of the insert by a clearance angle. A bent portion is formed from a middle of the clearance surface in an axial direction and has an attachment surface(302a) having a clearance angle same with the clearance angle of the clearance surface. A side wall angle is not more than the clearance surface of the attachment surface.
