Dual wall Standard bit

Variations available

The Standard type dual wall core barrel bit is suitable for a wide range of drilling applications.


Description

This bit offers optional front or side discharge. The discharge holes can be sealed using a hex socket screw which is included with the bit. 

While this bit is capable of drilling through extremely hard rock, switching to the Hard Rock bit is recommended for extended drilling in such conditions to improve efficiency and prolong bit lifespan.
