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




Wide range of applications

Cobalt-containing straight flute taps can be used for drilling of different materials, with a complete range of products.



Excellent selection of materials

Using excellent cobalt-containing raw materials, it has the advantages of higher toughness, good hardness and wear resistance




Whole grinding

The whole is ground after heat treatment, and the blade surface is smooth, the chip removal resistance is small, and the hardness is high.
