Push and Pull Diamond Core Bits

The push and pull diamond impregnated bit is a specialized tool that is commonly used in underground drilling for a variety of reasons, such as service holes for air, water, paste fill or sand fill.


It is a much larger, bi-directional bit with a diamond matrix. The push and pull bit is used to expand the diameter of a bore hole once a diamond drill has accurately drilled a pilot hole in a common standard size such as NWL.


  • Saves time – it is much easier and quicker to expand an existing smaller hole than to drill a large diameter hole.
  • Can be used with smaller underground drill rigs.
  • Causes less vibration resulting in less wear and tear on equipment.

We are happy to announce that as of August 2, 2021, all Canadian Fordia offices will be making drill rigs available to their customers. In an earlier blog this year, we announced that drill rigs would be available for sale in the USA and that proved to be successful, so Canada will now join the USA in adding drill rigs to their portfolio of drilling equipment for the mineral exploration industry.

The mineral exploration industry has seen a lot of change in the last few years. One of the most common challenges is finding employees. Between the cyclic nature of the industry and the recent pandemic, many experienced drillers have left and replacing them has been difficult for many companies.

At the beginning of the year, we decided to update our popular eGuides so our customers would have the latest and greatest information. We started with our most popular guide on choosing the right core bit and are now in the process of taking each guide and updating its information to represent the many changes that have occurred over the last few years.

Customer service is our priority.
