To select the right bit for the job, assess the speed and power of your drill for the size and depths of the holes to be drilled and assess ground conditions such as rock type/formation and down-hole conditions.

Size:
JS bits are available in all standard drilling sizes. Also, non-standard sized bits can be produced according to requirements from clients.
