[Prior Art] Please refer to FIG. 4 and FIG. 5; ^The cutting tool does not include a clamping rod portion 90, and a drilling portion 91 is formed on the side of the clamping rod portion m, the body portion 91 is provided with two chip rows φ, Α Λ 4 4 93, and a cutting edge portion 92 is formed between the chip discharge grooves 93, and the blade edge portion 92 is at the highest point of the free end of the body portion 91. An inclined end face q4 ^ ^ turns 94 is formed, and a ridge line 95 is formed adjacent to the two end faces 94. Among them, when the conventional cutting tool is used for cutting and cutting, the ridge line 95 formed by the end surface 94 is firstly smashed +71 from the surface of the workpiece by t, ^叮 and #, and the cutter is rotated. When cutting, the ridge line 95|cuts the squad... and cuts this force, causing high-speed friction between the cutting tool and the processed material, and the guide wire does not cause an increase in the longitudinal force of the cutting tool during machining, resulting in an unstable rotating pole. , ice / g ^ ^ release shake, so that the drilling position accuracy is reduced, and this design uses the two-knife part 92 material ι u I, | cutting the machined material, if the workpiece is two different types of cutting , J 柯 柯 柯 , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , The manufacturing process of the plurality of knife edge portions 92 and the end faces 94 is time consuming and labor intensive; and the spiral debris discharge groove 93 of such a design has the curvature of the groove being the same as that caused by the workpiece during processing. Not easy to break and discharge, resulting in The cutting edge 92 of the cutting tool will be greatly cut 3 M396168 when cutting, which not only affects the cutting and cutting of the cutting process, but also causes the cutting tool to overheat and affect the strength and the cutting force, and is easy, .^ _ 'When cutting, the processing material is prone to burrs, so it is easy to think and solve the problem that the tongs simplify the cutting tool and reduce the loss and enhance the debris discharge. Problem [New content] The main purpose of this creation is to provide a single-edge cutting tool, which is designed to improve the time-consuming process of the cutting edge of the conventional cutting tool and the problem that the debris discharge is not fast enough. In order to achieve the above objective, the single-edge cutting tool designed by the present invention comprises: ~ a clamping rod portion; and a drill body portion disposed at one end of the clamping rod portion, the highest point of the top portion of the drilling body portion Forming a center of a vertex, and forming a longitudinal longitudinal edge portion having a longitudinal cutting edge, the longitudinal cutting edge and the outer diameter of the body portion of the drill body forming a cutting edge, and a transverse cutting edge is formed between the longitudinal cutting edge and the center of the circle The rear end of the longitudinal knife edge is centered on the center of the core, and a downwardly inclined cutting surface is formed in the clockwise direction, and a first ridge line is formed at the joint between the longitudinal knife edge portion and the cutting surface, and the rear end of the cutting surface is centered at the apex, clockwise direction Forming a conical surface, a second ridge line is formed at the junction of the cutting surface and the conical surface, and the conical surface is extended toward the body portion of the clamping rod portion to form a spiral debris discharge according to the above, the single-blade cutting tool is When cutting, the center of the drill body is first brought into contact with the surface of the workpiece. The pressure at the point of contact with the center of the circle is concentrated, and the bite can be stabilized with the workpiece. The 4 M396168 ' in the workpiece enables the single longitudinal edge portion to be quickly drilled into the workpiece, reducing the instability of the cutting process and avoiding damage to the longitudinal edge portion of the cutting tool, and the drilling position accuracy does not change; The debris can be automatically discharged by the two different curvature grooves of the chip breaking function, which can reduce the loss during the cutting process and prevent the debris from being discharged, thereby improving the single-edge cutting tool. The cutting ability, so it can play an excellent cutting function 'to benefit the industry.
