The above chart represents commonly available sizes and types, we do produce other sizes and types of rock bits which do not appear on this list. Please contact us for more information.

 

 

The RPM applied to a bit will be a function of :
 

a. Type of bit


In general lower RPMs are used for insert bits than for milled tooth bits. This is to allow the inserts more time to penetrate the formation. The insert crushes a wedge of rock and then forms a crack which loosens the fragment of rock.
 

b. Type of formation


Harder formations are less easily penetrated and so require low RPM. A high RPM may cause damage to the bit or the drill string.
