Diamond core drill bits

Diamond core drill bits are used to drill a number of different materials. Diamond drill bits help to make the process more accurate and assist in making the final project look neat with a limited amount of clean up. Diamond core drill bits can be effectively used in exploration drilling as the drill bits are able to hold a certain amount of the materials which are mined.

The diamond core drill bits consist on a number of industrial strength diamonds placed in a toughened steel matrix. As the drilling begins and continues the matrix will slowly wear away, exposing the diamonds. The diamond core drill bit becomes more effective once this takes place. Once a project has been completed the diamond core drill bits are removed from the machinery and packed away in an organised fashion. The diamond core drill bits are packed into containers called core trays and they need to be washed and measured after use.

The diamond core drill bits are very important in the aftermath of the mining procedure. The packed away drill bits will be analysed by teams of specialists who are then able to determine what type of materials are found within the exploratory mine shaft. The diamond core drill bits are incredibly reliable as they are made from industrial strength diamonds. These drill bits are unlikely to break or even be damaged.
