Product Description

Drilling core tube of drill bit for drilling rotary pile driving in road construction


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.



Screw bit:

Ø Large diameter drilling

Ø Straight spiral design, convenient for handling slag.

Ø Double-headed spiral, uniform force, not easy to run off.

Ø The double helix has strong slag carrying capacity, and the single helix is easy to unload the slag.

Barrel bit:

Ø Built-in anti-suction drilling

Ø One-piece center cone, curved guide plate with teeth, large drill bit and double bottom drilling mechanism design

Core bit:

Ø High drilling capacity

Ø Slightly weathered granite requires the use of roller core bits, and the use of pile core bits for severely weathered rock formations can reduce the cost of roller bullets.

Iron drill:

Ø It is a kind of barrel drill bit.
