Product Description

 

The drill bit is an essential part of the drilling process. It is easy to choose a drill bit that is ‘good enough’ for the application yet if we identify the best choice, then dramatic savings in drilling cost will be made. Bit selection commonly involves choosing a bit that offers the right balance between durability and Rate of Penetration. The goal to get the maximum rate of penetration and maximum durability in the one bit. The right balance between the two will yield an optimum ROP and optimum durability for the application.
