Choosing a tool and working with it
Choosing the appropriate tool is important when deciding on a concrete drilling technique. A good drill with an attachment can penetrate the wall fast and precisely. Not every tool works equally well for this kind of work. A subpar concrete drill will take a long time to complete and might not work at all.
When selecting a tool, consider the following:
- the presence of a speed controller. It is important to be able to adjust the number of revolutions for accurate drilling. Working exclusively at maximum speed will lead to drilling a large hole and damaging the surface;
- the ability to set the impact mode of the drill. Useful for punching through layers with a higher density;
- adjustment of the depth of the drill;
- the presence of an auxiliary handle in the kit. A professional and powerful drill is a heavy power tool, it is better to have a built-in handle for working with two hands;
- satisfactory power indicators, so that it is convenient to drill concrete, brick and other materials, because a drill is a universal tool.
Selecting an instrument and operating a drill are crucial steps; failure to do so will result in increased material deterioration and wall destruction. It’s critical to choose the appropriate drill for drilling a concrete wall after determining which drilling machine option is best. Stone-specific carbide-tipped attachments are readily available in stores and work perfectly with concrete.
It is best to become accustomed to using the chosen tool before beginning work. It ought to be easy to operate with one or both hands. One hand is placed on the handle, and the other is either on the body’s side or the detachable handle.
To avoid distortions and coating destruction, the drill must always be held precisely at a right angle to the surface.
It is advised to wait until an electric device reaches room temperature or cools down before turning it on because all electric devices are susceptible to temperature fluctuations. Condensation is a possibility with abrupt changes. It is preferable to unplug the power tool from the network if there is no immediate need to drill.
Surface preparation
Prior to drilling any holes, confirm that the area you have chosen is clear of any wiring, pipes, or cables. Using a metal detector is an easy method to find such elements. Since reinforcement is almost always present in walls, it is preferable to first set the metal detector to detect non-ferrous metals (such as wiring) and then steel. There is a chance that you will encounter reinforcement if you disregard the condition, in which case the carbide drill will be completely destroyed.
First, a point on the wall is designated. Create a recess using a drill at a low speed or any sturdy metal object to stop the tool from slipping. The concrete drill easily penetrates the wall after meticulous preparation. It is important to keep in mind that the cladding that is put on top of the cement is softer than the wall itself, so the drill glides through the material easily at first before hitting a sturdy object.
Choosing a drill
The right drill for drilling a concrete wall depends on the holes and type of material. Making the correct decision will improve the attachment’s integrity, quality, and accuracy of the outcome. Special drills for different kinds of materials, such as metal, concrete, and wood, are available in the stores. The triangular tip shape and the carbide composition applied to the tip are the key characteristics of concrete drills. Concrete can be crushed with a standard drill and a carbide bit without tearing the material.
If the process stops while drilling holes in the concrete with a drill, either the impact mode is activated or holes are drilled with a hammer drill. A hammer drill’s biggest flaw is its large holes, which start at 13 mm in diameter. Dense areas are easily penetrated by a mechanical hammer punch. Punch the area until the material gives way. Next, keep drilling the hole.
To drill several holes in concrete, a nozzle with special soldering is used:
- carbide tip;
- universal drills, but they should be cooled regularly;
- diamond drills for concrete are a relatively expensive material, but durable.
Make sure there are no strange sounds coming from the metal contact while drilling. If you hit wall reinforcement, it’s crucial to finish the process while the nozzle is still pointed.
Three steps are necessary for properly drilling concrete with reinforcement:
- Reach the layer with metal with a carbide tip.
- Install the drill for metal – the reinforcement is soft and should be easy to drill.
- Continue working with the drill for concrete.
Although drilling concrete can be difficult, most do-it-yourselfers can handle it with the correct equipment and methods. The secret is to start with a smaller hole and progressively enlarge it if necessary, use a hammer drill fitted with a carbide-tipped masonry bit, and maintain drill stability while applying uniform pressure. In order to protect the drill and the surface, it’s also critical to wear safety gear and refrain from applying excessive force.
A little about the structure of the drill and installing the drill
A typical drill consists of:
- a cable from the network;
- a power button;
- condenser wires;
- a reversible system;
- brushes with springs;
- anchor;
- stator;
- a gearbox with a chuck;
- bearings;
- keys;
- screws.
The quality and safety of the work improve when the drill is installed correctly. Drill injury is possible if the nozzle is slightly tightened. It is advised to insert the attachment until it stops, then use a unique key to clamp it.
Never attempt to lengthen the rod by inserting it partially into the chuck.
It is advised to make sure the drill is firmly positioned in the center along the axis before using one to drill concrete. The rod could break or fly out of the chuck if there is even the smallest shift because the hole will be too large.
You should inspect the drill for contamination before beginning any work. Cleaning the drills with a rag is preferable. Applying force to the handle all at once is the simplest method for drilling concrete.
Selection of power for drills
It is recommended to use a drill bit with a 600 W power and 2500 rpm when drilling concrete. Read the drill manufacturer’s recommendations to choose the rotation speed more precisely. Concrete is drilled using the crumbling method, which doesn’t require fast speeds.
Errors when working with a drill
The following behaviors during drilling were identified with the assistance of the workers’ comments:
- You cannot hold onto the rotating chuck during work. There is a housing or handle for safe holding;
- If you work with gloves, you should use tight-fitting varieties. The protruding ends of the gloves can twist during rotation;
- Pressing the drill with all your might is not the best solution, since the builder loses balance and can fall. Another problem with excessive force is breakage of the drill;
- It is important to avoid having a person"s hands on the back side of the concrete, otherwise the drill will go through the wall and can cause serious injury.
Although drilling into concrete can seem difficult, it can be a simple task if you have the right equipment and know how. Don’t forget to select the right drill bit for the job—a carbide-tipped masonry bit, for example, is ideal because it can handle the material’s high hardness. To prevent overheating and harming the drill bit and the drill itself, start with a low drill speed.
When working with concrete, a hammer drill is also a must-have tool because it delivers fast, forceful blows that facilitate more effective material breaking. Use consistent pressure while drilling, then let the tool finish the job. Overpressing can cause overheating or bit breakage. When drilling deep holes, remove the drill occasionally to clear the hole of dust and debris that could clog it and prevent you from moving forward.
Another important factor is safety. To protect yourself from flying debris and concrete dust, always wear protective eyewear and a dust mask. In addition to being aware of any potential hidden plumbing or electrical wiring, secure the area you’re drilling into to prevent any movement. You can drill into concrete and increase the efficiency and safety of your do-it-yourself projects by using these tips.
