1. Product Function: The main function of the keyway broach is to process the keyway in the inner hole of the workpiece. 2. Product Features: Large broaching allowance, keyway broach design makes it possible to remove more metal in the process, suitable for occasions requiring a larger amount of cutting; the number of teeth, due to its design features, keyway broach usually has more than one tooth, which can improve the processing efficiency and accuracy. 3. Application scope: Widely used in a variety of occasions that require keyway machining of the bore, especially in batch and mass production, its high efficiency productivity and accurate machining results make it an indispensable tool. For example, in machinery manufacturing, automotive parts production and other fields, keyway broaches can quickly and accurately complete the keyway processing, improve productivity and product quality. 4. Material: Made of high hardness, high wear resistance and high heat resistance tool steel H.S.S, it can provide good cutting range and sufficient rigidity.
