T thread drill bit includes EX, EXX, EY, EYY, ESS-F, clay bit, etc.

Description

Introduction:

Drill bit is made from steel which can provide enough hardness in rock mass. It is used for drilling and installed on the head of anchor bar. As self drilling anchor bar just needs to be installed into the rock directly, the drill bit is used for only one time.

Characteristic:

1. Sinorock has kinds of drill bits to meet different demands, which includes EX, EXX, XX, ES, EYY, ESS-F, clay bit, aggressive soft soil.

2. It's suitable for various ground conditions.
