Single wall Heavy duty bit

Variations available

The combination of dome buttons, wear protection, water slots, inner cutting buttons, and overcut makes this bit highly effective in tougher drilling conditions.


Description

Note: While this bit is capable of drilling through tough soils, switching to a dual wall core barrel bit is recommended for extended drilling in rock formations to improve efficiency and prolong bit lifespan.

Important: the CB4 Single wall heavy duty bit can only be used in combination with the EM7 casing.
