Shenyang ABT Drilling Equipment Co., Ltd.

Opener Bits

In construction often encountered in the original hole, or the need for a second drilling hole into the situation, at this time need to enlarge the hole.

In view of this situation, our company designed a reamer bit, and added a guide head in the center of the drill striking surface, which solved the problem that the impactor could not operate normally due to the high-pressure air leakage in the reaming hole, and ensured that the back opening was concentric with the original hole.

Different reaming bits are selected according to the different requirements of the drill.

The drill bit shall be selected according to the original hole diameter and hole diameter.

Our company can customize according to customers' needs.
