The information contained in this section is intended as a technical guide for the field application of Dimatec core drilling bits. To use these products successfully, it is necessary for the driller to provide some control over the three primary operating parameters which are:

• Bit Load or weight on bit (WOB) - the thrust applied to the bit during drilling,
• Rotational Speed and
• Bit Hydraulics - the type of circulating fluid and the rate at which it is pumped through the bit during drilling.

The technical application data provided here is intended as a basic guideline for the selection of the appropriate tools for your job and the normal operating requirements for their application. As drilling conditions and the capabilities of drilling equipment vary considerably from site to site, it is impossible to define absolute application recommendations. Some experimentation on the part of the user may be required as operating parameter values outside of the ranges suggested here may be applicable to your particular conditions. Technical support is available by contacting Dimatec directly.

Conversion Factors

While using the data contained in the specific sections concerning operating parameters, it may be necessary to convert between metric and imperial units depending on the instrumentation of the drilling equipment in use. For your convenience, the relevant conversion factors for units used for the various operating parameters are given below:
