Description
Another important classification of drilling bits are engineering bits, also known as rotary digging bits. In recent ten years, with the investment of real estate and national infrastructure projects, rotary digging buttons have been fast developed in the field of pile foundation. The manufacturers of rotary digging bits and the supply of rotary digging bits are continuing to grow.
