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