Concrete is one of the hardest materials used for construction purposes. To drill holes in concrete or cut through the material, powerful core drilling equipment will be required. Core drills specifically designed for cutting or drilling in concrete are called diamond core drills. These drills can be used for wet cutting as well as dry cutting of concrete. To ensure you get the right drill for your job, it is important that you understand the differences between wet cutting and dry cutting of concrete.  

Read on below to find out the ways in which the two concrete core drilling techniques are different.

Wet concrete core drilling

This work technique involves core drilling in concrete with water. Water is usually used to help suppress the dust that is produced while drilling is ongoing. For effective wet drilling in concrete, it is important to use just the right amount of water. 

If too much water is used, all of the concrete dust particles produced may be washed away, preventing the diamonds in the drill bit from being exposed. Add water only until the slurry is as thick as creamed coffee. This will ensure the diamonds remain exposed and touch the slurry while concrete is being drilled. 

If you don't use enough water, insufficient amounts of slurry will be produced and the drilling process will be ineffective. 

Dry concrete core drilling

This involves drilling in concrete without water. It is an appropriate work technique when drilling with water is not a feasible option. If there is an electric power line near the work area, then drilling with water may not be a safe option. In such a case, dry drilling will the best option. 

Fortunately, water is not the only means of suppressing dust. There are several types of on-tool exhaust ventilation systems that can be used to minimise the amount of dust that circulates in the work environment when dry drilling in concrete. 

Under no circumstances should the harmful effects of concrete dust be disregarded because the dust can lead to diseases such as silicosis if not controlled.

Irrespective of which of the above work techniques is chosen, all those handling concrete core drilling equipment MUST follow all applicable protocols required to ensure safe use and operation of the equipment. The good news is that there are many good concrete contractors who can perform your job properly and safely, so don't hesitate to seek assistance if need be.
