THE MOST HELPFUL TIPS FOR CORE DRILLING
                     THE MOST HELPFUL TIPS 
FOR CORE DRILLING
The core drilling is safely done with both hard work and patience

Picking the appropriate 
attachment:
Specific stands are required depending on where you want to drill specific 
holes. When drilling on slabs, for example, you must use a vacuum stand with 
suction power. The mechanism will remain attached to the floor in this manner. 
It is not essential to drill an anchor hole in these cases. It is essential to 
safeguard the stand when core drilling the wall. This is accomplished through 
the use of safety chains, which eliminate the possibility of accidental slips.

Picking the right drilling 
machine:
For testing the compressive toughness of the concrete, a wide range of drill 
machines are available. These commodities are available for purchase or 
rental, but they are a wise investment if you intend to make core drilling a 
regular part of your construction process. Core handheld drills can make holes 
up to three inches in diameter. However, if you want to spring test concrete for 
strength effectively, you must drill a hole at least 3.7 inches in diameter. There 
are no handheld drills accessible for this purpose, and instead, a drill stand unit 
or rig-mounted drill is required. Those interested in buying one of these units 
must glance for a model with multiple functions. This results in better value for 
money. These models can be used for both electrical and plumbing holes and 
dowel-hole drilling.

Recognize your power 
options:
The core drill can be powered by one of three methods. There are three types 
of sources that are air-powered, electric, and hydraulic. The supply of electricity 
and the work environment at the site determine which source is required for 
your drilling needs. Various models allow for appropriate speed selections 
based on hole size and concrete hardness.

Drilling depth is essential:
Regular core drilling solutions are offered with one-foot-long bits. When drilling 
requirements exceed this, it is critical to use barrel bits. These barrel bits are 
extensions that allow for a deeper drill than the size of the pre-existing cutting 
bits. You can change to deeper depths if your needs change, but recognize to 
take into account the style of extension that will provide the best results in 
different drilling scenarios.

Picking a diamond bit:
Before selecting the right diamond bit, consider the overall average hardness 
and psi of the concrete material. The core diamond bit must be precisely 
proportioned to the surface or drilling material to achieve the best results. 
Remember the rule that when drilling on hard floors, use a soft diamond bond, 
and when drilling on soft surfaces, use a harder bond. However, there is no set 
remedy, and you must always use your discretion when picking your diamond 
bit based on the situation.

Safety should be the main 
priority:
Safety should be your fundamental concern regardless of the nature of drilling 
you are doing or about to do. From the outside, nothing serious may happen, 
but over the years, even professional drillers have suffered severe injuries. 
Core drillers may necessitate wearing goggles, gloves, and earplugs to avoid 
injury. Never jeopardize your safety or underestimate the drilling process.

Always follow the instructions:
Given that core drilling machines are designed to create holes in hard materials 
such as reinforced concrete, masonry, and granite, workers must strictly 
adhere to the guidelines issued by the machine manufacturers to maintain 
proper safety. For example, they should not use the equipment for purposes 
other than those for which it was designed. It means that you should not use a 
core drilling machine for anything other than making holes in reinforced 
concrete, granite, and masonry, for example.
