Analysis on the Problem of Premature Breaking of Taps:

Reasonable selection of taps: The tap type must be reasonably determined according to the workpiece material and the depth of the hole;The bottom hole diameter is reasonable: for example, M5*0.8 should choose 4.2mm bottom hole. Misuse of 4.0mm will cause breakage.;Workpiece material problem: the material is impure, there are excessive hard points or pores in the part, and the tap instantly loses balance and breaks;Choose flexible chuck: set a reasonable torque value with a chuck with torque protection, which can prevent breaking when stuck;Synchronous compensation tool holder: it can provide axial micro-compensation for the non-synchronization of speed and feed while rigid tapping
