7 Effective Ways to Use Diamond  Drilling Equipment

The overall performance of diamond drilling varies with material hardness, density, drilling depth, and a few other factors such as material shape, the coolant being used, rate of penetration (ROP), and diamond drill bit. One can optimise the diamond drilling performance by following the principles of proper usage of diamond drilling.

Some trial and error is involved when one uses diamond drilling. But diamond drilling Kent uses variations to improve diamond drilling operations effectively even when working on the same material and application for several years.

Each variable of the diamond drilling process is only one of the many parameters of a diamond drilling equation. Changing one variable of the diamond drilling process will not guarantee an efficient result alone. Only when all variables are added together can desired results be achieved, making the entire process smooth and effective.

Please read on to understand what factors can affect the efficiency of your diamond drilling equipment.

1. Improve ROP

ROP optimisation is one of the most critical factors in improving drilling efficiency, especially in the downturn time of oil prices. It is essential in exploration phases to choose the appropriate drilling bit as it significantly impacts the cost and time of the drilling operation. Hence, the optimisation and best selection of drilling parameters are essential.

ROP results from using the correct weight on bit (WOB), water circulation and rotation speed (RPM). It is the primary parameter for the success of diamond drilling. To have a good ROP, you need to get in touch with diamond drilling Kent as per the rock type and condition and combine it with the suitable core bit and crown configuration. With the improved ROP, you can get high-quality results with minimum effort.

2. Extended Bit Life

Having longevity for your core is critical for running a productive and profitable drilling operation. Changing a drill bit is time-consuming and will affect your drilling operation.

For example, an average bit is about 125 meters, and you need to drill 1000 meters; you may have to change a drill bit 8 times. In this case, if you extend the life of a bit by 15%, you will have to replace the bit fewer times. The further you drill, the more time it will save. Here are a few tips that can extend the life of your drill bit:

  • Choose the most suitable drill bit per the material you want to drill.
  • Use additives.
  • Have the correct waterway configuration.
  • Ensure proper and sufficient water flow.
  • Use a crown matrix especially customised for the group type.

3. Select the Right Equipment

It is essential to select the right equipment as it influences the drilling performance. Before choosing the right drilling equipment, you must consider some factors, including ground hardness, abrasiveness, variability, competency, depth of drilling, and the type of drill rig used. The core barrel, reaming shell, drill rods, and core filter system can also affect diamond drilling productivity.

4. Use Higher Crowns

The higher the crown, the higher the meters you can achieve before changing a bit, and it is essential to drill a hole. You can use a crown with a valium configuration as it also helps with the longevity of the dill bit it refers to the height of the peak and comes in 16 or 26 mm.

Some grounds will eat through a diamond bit more quickly than others, so a higher crown will decrease the time you need to pause the drilling operations, resulting in increased productivity.

5. Regular Maintenance

Proper diamond drill care and maintenance are crucial to optimise the drilling performance. Maintenance of the shape of the diamond section and rigidity is essential to prevent the drill from losing sharpness and roundness. If you find out the diamond drill has lost its rigidity and shape, please replace it or send it to the manufacturer if it is under warranty.

6. Use Coolant

Diamond tends to heat up without coolant, affecting the drilling operation. It is best if you use coolant to lubricate the drill; otherwise, the drills get damaged. Never run a diamond drill without lubrication to flush out the abrasive particles formed while drilling.

Water is the most common organic coolant used in diamond drilling as it does not leave material greasy or contaminated. It will reduce wear and tear and limit rust on rods. Water will ensure that drill mud has the necessary viscosity to easily carry and flush rock cuttings from the borehole and keep them from setting at the bottom of the hole.

Other types of coolant are available, such as mineral oils and synthetic water soluble, but if you plan to use water as a coolant, please check with the drill manufacturer about the required water pressure and if any additive is recommended. Please note that using additives requires a circular system to ensure the accurate ratio between additive and coolant.

7. Be Organised

The success of any diamond drilling procedure depends on how well-planned the whole operation is. Prepare a list of everything you need for your diamond drilling project. It will save you time and effort. It is even more critical to plan well in advance if the site is remote, as it could take a while to reach there. Please ensure the plan includes all the necessary parts of diamond tools, pumps, engines, fluids, consumables, accessories, and other relevant things.


The diamond drilling industry is constantly changing, and CA Drillers ensure to change with time and bring in updated techniques to provide the best diamond drilling result. The material being drilled can vary in composition even if it has come from the same source. A minor change in ROP or coolant feed can make a lot of difference.
