Diamond Core Drill Basics You Should Know
January 24, 2020

Diamond core drills are predominantly used to drill masonry, concrete and asphalt thanks in no small part to their accuracy, speed, and efficiency.

 

 

To help you in your journey of understanding why reliance on these core drills remain so steadfast, we’ve taken the time to outline just a few of the many reasons why they remain such an effective drilling tool.

 

For starters, let’s ‘drill’ some of the basics into your head…

 

What Exactly Are Diamond Core Drills?

The essential elements that make up a diamond drill are a rotating metal cylinder or a steel tube with industrial-grade diamonds fixed into a metallic, soft matrix found on its rim. Similar in vein to a hole saw, they remove a cylinder of the worked material and bores out a hollow center, hence the name.

 

How Do Diamond Drills Work?

Powered either by electric, pneumatic, or hydraulic means, a diamond drill is then provided the energy to spin and bore through the material in question. During this drilling process, the soft metallic matrix wears away and exposes new sharp diamonds to grind and remove the unwanted material. As the diamond core drill deeply penetrates the material, unwanted parts then go on to be housed within the core tube, i.e. the circular opening at the end, and can be recovered as it piles up. Orientation is seldom an issue as diamond drills can handle these aforementioned tasks either vertically or horizontally.

 

Diamond Drill for Wet or Dry Applications

During a wet core drilling, water helps control the temperature of the core while also serving to get rid of dust and aiding in prolonging the tool’s service life. Water core drilling is employed in many applications including masonry, plumbing and drilling into concrete to install load-carrying devices or to conduct concrete analysis.

 

While most core drilling is performed wet, it can also be done without the use of any water. Dry core drilling is preferable in applications where water may not be practical to use, e.g. work carried out in a fully furnished office or house, or even an establishment involving trepidatious exposure to electrical wires. Be mindful of the fact that absence of water, while core drilling, exposes the core drill to stress and pressure which can in turn lead to the drill slowing down.

 

Due to their inherent design, diamond drills are renowned throughout industrial settings for being one of the most effective tools used for any sort of drilling application. Don’t take this as a pass to source any old tool for the job; on the contrary, it takes an idyllic diamond drill bit to impart the clean and accurate holes you expect so that you can get things moving along with the installation or even to the next operation.
