Stable Rotary Drilling Tools Rig Tap Hole Core Barrel Screw Bit

Rotary drilling rig tap hole, core, barrel, screw bit

Introduction
It is very difficult to directly cut boulders and hard permafrost layers with auger bits or rotary drill buckets. Therefore, the drill barrel is designed to work with drilling augers and cleaning bits.
The drill barrel is divided into core type and non-core type. According to the different drilling strata, it can also be divided into the pick type of weathered bedrock permafrost and the cone type of hard bedrock.

Features
1) The core barrel with elastic teeth is used to cut annular rings in rock or concrete (including reinforced concrete).

2) The core barrel with roller bit is used for very strong rock formation (compressive strength> 100Mpa).

3) The cross cutter core barrel is mainly used to break the core that is left in the borehole after the core barrel is used. It is also suitable for drilling hard jointed rocks (<100Mpa) and penetrating layers containing boulders.
