Diamond-core drilling

diamond-core-drillingWhen a large piece of cylindrical material needs to be removed then diamond core drilling is the best method to use. The drilling bit of this piece of equipment is fitted with diamonds which are able to cut through most materials quite easily. Diamond core drilling gets its name from the diamonds used to cut the materials. This method is often used to cut a cylindrical shape out of concrete. But diamond core drilling is not used to only cut cylindrical holes. The diamond core drilling process is also used for a number of other purposes and has a number of benefits that other forms of drilling do not have.

Industrial strength diamonds are placed into the hollow end of the drill bit and they are used to cut away at almost any strength of rock or other material. The use of diamonds makes the drilling process more accurate and as the diamonds have incredible strength, the drill bit will last longer. Many mining and drilling procedures are noisy and dusty but this is not the case when it comes to diamond core drilling. The process involves the use of light and easy to transport equipment and it can be used in just about all locations including underwater. The procedure is incredibly safe and it can even be operated from a remote location which opens up the variety of places and situations in which it can be used. There are a variety of different diamond drill bits that can be used on a variety of different materials. Each drill bit is created for a specific purpose and the drill bits can be changed according to the needs of the project.

What are the advantages and disadvantages of diamond core drilling?


  1. Drilling can be done quickly and effectively with little noise and little dust. A 4mm hole can be cut through a brick wall in under a minute, highlighting the speed of the process.
  2. Diamond core drilling can be done almost everywhere.
  3. Diamond core drilling can be done remotely which limits the safety hazards.
  4. The cuts that are made are highly accurate.
  5. It does not require a lot of effort from the operator.


  1. One of the greatest drawbacks to diamond core drilling is that the drill bits are often not very big and they are mostly able to cut through only stone, rock and cement.
  2. There is a powerful kick back from the machinery so caution needs to be applied when using diamond core drilling.
  3. While dust will not accumulate in large quantities some dust is likely to go into the drilling machine which can have an effect on its functioning and effectiveness.

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.
