- One of the key advantages of tapered rock button drill bits is their versatility. They can be employed in both surface and underground drilling operations, making them a versatile choice for mining, quarrying, and construction projects. Their ability to maintain consistent performance across different drilling depths and angles further underscores their value.


Molded gratings include:
At present, the joint laboratory’s first R&D project – on spray paint – free carbon fiber composite materials – has been officially launched. The product will be used first in new energy vehicles, not only to reduce the weight of the body, but also to significantly reduce the application cost of composite materials and improve production efficiency.

30mm drill bit. Its sharp cutting edges and point ensure that you can create clean, accurate holes with minimal splintering or tear-out. This is especially important when working on projects that require a high level of detail and accuracy.
