Prism Core Bit Profile

Exploration diamond drilling will often require the use of directional tools, such as a wedge, to help steer the borehole. 


Once the wedge is in the borehole, care needs to be taken with all the down hole tooling, especially the diamond bit, as it can suffer damage to the tip of the crown or worse, drill through the wedge. Our PRISM60 crown profile provides the perfect solution for such situations.


PRISM60 Crown Profile

This specialized bit is the best choice for making the first cut and drilling past wedges already set in the borehole. The Prism60 bit has a smoother 60 degree chamfer on the leading edge of the bit and the inner and outer diameters have been reinforced with diamonds to provide better cutting capabilities.


Instead of the usual “w” pattern, the crown of the wedge bit is flat to provide more matrix and longer life. New and improved waterways also ensure that sufficient water flow reaches the shoulder of the bit to cool it adequately and keep it intact.


  • Optimized waterways for better cooling of the crown at the contact of the wedge blade
  • Improved outer gauge protection
  • Superior angle of attack on the face of the bit for successful drilling past a wedge
  • More reinforcement at the shoulders with carbide strips to maintain gage
  • Comes in a choice of matrices according to ground hardness

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.
