Abstract

The invention discloses a durable broach. A handle part (1), a neck part (2), a transition cone part (3), a front guide part (4), a cutting part (5) and a rear guide part (6) are sequentially arranged on the broach from front to back. The handle part (1) comprises a head part (11) and a connecting part (12), a transition part (13) is arranged between the head part (11) and the connecting part (12), the planes of the two sides of the connecting position of the head part (11) and the transition part (13) are mutually perpendicular, and an inclined plane is arranged between the transition part (13) and the connecting part (12). By the adoption of the improvement of the durable broach, even if the transition part turns up when machining is performed, the durable broach can still be normally used, and the machining is not affected. The service life of the broach can be prolonged, and production efficiency can be improved. In the using process, the broach does not need to be corrected and therefore machining cost can be reduced.

Description

technical field [0001] The invention relates to a broach. Background technique [0002] In the prior art, the handle 1' of the broach is used to clamp the broach and transmit power, wherein the handle 1' includes a head 11' and a connecting part 12', and the connecting part 12' is used to connect the head 11' and Neck 2'. There is a bevel 13' between the head 11' of the shank 1' and the connecting part 12', but when the bevel 13' is flanged due to use, the broach cannot be used and needs to be trimmed before use. [0003] Therefore, a new durable broach is needed to solve the above problems. Contents of the invention [0004] Purpose of the invention: the purpose of the invention is to provide a durable broach to address the shortcomings of the prior art. [0005] Technical solution: In order to achieve the purpose of the above invention, the durable broach of the present invention can adopt the following technical solution: [0006] A durable broach, the broach consis...
