Since the recent launch of our impregnated bits, we have many requests for an application chart.

Drillability of a formation is notoriously difficult to assess accurately without a drilling trial, and to overcome this obstacle Premier has opted for an approach that offers a small selection of products, each with a wide and tolerant range of application.

Apart from finding the relevant mineral in the application chart or evaluating hardness using the Mohs scratch test, the most popular way to select product on an existing job is to look for the Premier alternative to a competitor’s product whose performance is already known.

In response to this approach, we have developed a chart which should be comparable to most others in the market so that the user can find the Premier equivalent that matches the mineral application range for the other suppliers’ product of interest.
