Finally, the wait is over, and we will continue the article here. In the previous article, we discussed preparing for concrete drilling. In this article, we will focus on the drilling process. Let’s get started.

Need for using coring stand:

A coring stand is a core drilling frame that can be attached to walls, ceilings, and floors. It is crucial for holes that require extreme accuracy.

Core drillers use stands for difficult positions. Setting up the stand takes time, but it makes handling the drill easier and ensures precise holes.

Anchor installation:

The installation setup takes time because anchors are needed to fix the drill stand. For concrete projects, rock anchors are used, while in brickwork, metal tubes with Rawl-dowels work best. These fasteners secure the stand firmly and allow the drilling machine to perform optimally.

When anchoring to the wall, place it strategically to keep coring accessible in all directions. Anchors should be placed on waste materials or areas that won't affect the final design.

Coring:

After the installation of the stand, the main part comes here: creating the holes! Coring with a stand is the same as freehand coring but it gets difficult when inverted positions are involved.

To get desirable results, you must take precautions during freehand or coring with a stand. Failing to follow the rules can create disastrous results for the core drilling professional and the coring slab.

Here are the points to remember while using a concrete drilling machine:

Always remember forces on the drill machine are always high; therefore, it is important to:

  • Check if there is blue discoloration on the barrel (it indicates the heat marks)
  • Ensure there is no lost coring drill bit or any sign of cracking.
  • Stop and check for obstruction if the core drill shakes too much.
  • Always make sure to use water to clear the path and use manual obstruction removal.
  • Make sure there is no change in the slurry while coring, as it indicates a rebar encounter.
  • If drilling is going on very slowly, it means bits have gone blunt; sharpen them with sandpaper.
  • At all costs, don’t let water go inside the core drilling machine during inverted coring.

Important tips for core drilling:

  • Core drilling is a complicated process that only a trained professional can perform. Coring poses many challenges for core drillers on a day-to-day basis, and the ones with the smartest brains and knowledge can face them efficiently without creating danger to the slab or core drilling machine. Here are some tips to keep in mind while coring:
  • Analyze the material before starting the drilling and making your first cut. Check the strength of the concrete to make sure you don’t damage the current or adjacent slab.
  • Spot hidden utilities before coring. You can’t risk hitting rebar, pipes, and electric wires embedded inside the concrete wall.
  • Water is used for cooling the drill and lubricating it, so always make sure to turn on the water supply before you start coring.
  • The slurry is not entirely a waste product. It is abrasive in nature and helps with penetration and making the deeper cut. Retain the slurry inside the hole during coring.
  • Take proactive measures to prevent on-site accidents. Always wear a PPE kit and keep water and electric supplies untangled and far from each other.

Frequently Asked Questions (FAQ) on Concrete Coring with Core Drilling Machine

Q1. What is the importance of using a coring stand?

A coring stand is crucial for ensuring precision and ease when drilling holes, especially in difficult positions such as inverted drilling. It acts as a frame that can be attached to walls, ceilings, and floors, making it easier to handle the core drill and achieve accurate results.

Q2. Why does setting up a coring stand take time?

Setting up a coring stand takes time because it involves installing anchors to secure the stand firmly. For concrete projects, rock anchors are used, while metal tubes with Rawl-dowels are preferred for brickwork. Proper anchoring ensures the stability of the stand and the efficiency of the drilling process.

Q3. How should anchors be placed for optimal coring?

Anchors should be placed strategically to allow accessible coring in all directions. It's best to install anchors on waste materials or areas that won't impact the final design. This ensures stability and reduces the risk of damaging important sections.

Q4. Who should perform core drilling?

Core drilling is a complicated process that should only be performed by trained professionals. It requires expertise to handle the challenges and prevent damage to the slab or the drilling machine.

Q5. How does Concrete Insight ensure quality in coring services?
