Tool review
Concrete surfaces are processed using an electric drive tool.
Equipment with extra impact action is available, which enables you to drill holes in solid materials that are the right geometric shape. The larger weight and dimensions of diamond drilling rigs set them apart from other equipment used by construction or maintenance crews.
The user must understand how to drill a hole in a concrete wall without using a hammer drill if he needs to create a single channel and no electric tool is available. A steel rod or a length of pipe with teeth at the end that is the proper diameter is used for drilling.
After striking the rod with a hammer, the makeshift instrument is rotated by one-third of a turn. The process is laborious, and the hole edges are of poor quality.
Ham drill
An impact drill or hammer drill is used to drill holes in concrete; this instrument can create channels that are 500 mm deep. The equipment’s increased operating noise and the potential for wall destruction from vibration loads are drawbacks.
An additional drawback is the accumulation of a lot of dust; to install a vacuum cleaner hose bushing, a specialist tool is required.
A conventional drill or screwdriver
Using a manual tool or a regular electric tool to drill a hole in a concrete wall is nearly impossible. The tool lets you drill small-diameter holes in soft materials, but when you try to drill a concrete base, the drill breaks or becomes dull.
Concrete hard inclusions are broken up with a chisel or punch to make drilling easier. Without a hammer drill, drilling into concrete walls or floors is not possible.
Diamond drilling
Concrete reinforced with metal reinforcement can have holes drilled into it using a diamond crown mounted in specialized machinery. Water from the tool cools the crown and removes the resulting dust as it flows into the working area. There are no chips or damages on the channel’s edge, and the installation permits you to drill a hole with a large diameter.
Although it can seem difficult, drilling, cutting, or punching holes in concrete is simple if you have the right equipment and follow a step-by-step guide. Whether you’re using a hammer drill or a standard drill, knowing the steps involved will help you get precise, clean results every time. This post explains every stage, from choosing the right tools to using the drilling technique, so you can take on concrete projects with assurance and comfort.
Features of drilling with a drill
It’s crucial to choose tools and a drill with the necessary technical specifications when using a drill. Using an electric device with a speed controller and an extra impact mode is advised.
While drilling is sped up and the operator’s strain is lessened when using a side handle, a drilling depth controller is still necessary.
Drill device and drill installation
An AC collector electric motor is used in the drill design. A speed controller is part of the motor design and is situated on the power button. A gearbox can be used to increase torque and decrease speed; one tool has a 2-speed gearbox.
A chuck with a latch is used in hammer drills, and a cam chuck is fastened to the gearbox’s output shaft. A distinct block installed in the hammer drill gearbox guarantees that the drill will rotate in a reciprocating manner.
The drill must be fixed before drilling a concrete surface. After inserting the tool into the chuck, the jaws make sure the drill and the chuck axis are lined up. The drill is inserted into the chuck all the way along the shank; the working part of the tool cannot be extended by pulling the shank out of the chuck. To tighten the chuck, use the key that comes with the drill kit.
Power selection
A minimum 600 W power tool is needed to drill holes in concrete surfaces. The drill’s diameter and the properties of the material being processed are taken into consideration when choosing the rotation speed. By allowing the worker to independently choose the speed, less dust is released into the air and there is less chance that wall pieces will chip off during the drilling process.
Errors when working with a drill
Primary mistakes made when utilizing an electric drill:
- It is prohibited to hold the equipment by the chuck when working. Protective gloves and clothing should not sag or have dangling elements, since there is a risk of material winding around the rotating drill.
- You should not direct the tool at an angle or apply excessive force, since the worker may fall from a stepladder or ladder and get injured.
Surface preparation
The wall surface is marked, and the locations of the planned holes are marked with crosses made with a soft pencil. To create holes, some users employ a core. In residential areas, a polyethylene film is placed on the ground before drilling commences. Household waste is disposed of along with the gathered concrete chips.
Choosing a drill
The work is done with a drill or a concrete drill bit. A common question among cost-conscious users is whether a metal drill can be used to drill through concrete walls. The tool becomes unfit for further use when the working edge wears out while attempting to drill.
By analogy, channels in parts made of ferrous or non-ferrous metals or alloys should not be drilled using a concrete drill.
Preparation for work
Prior to beginning work, the drill is put into the device. The room’s central power supply has been turned off. Extension cords are connected to the junction box and are used to supply current. In order to shield their eyes and respiratory system from dust, the operator dons safety glasses and a mask.
Drilling a hole
The user must understand the proper technique for drilling a concrete wall. On a wall that has been designated, a tool with an auger or drill installed is placed. With the right hand, grasp the equipment by the main handle, while the left hand holds the drill body.
If the equipment has a side handle, the operator uses his left hand to support it while firmly holding onto the handle.
After the drill is positioned against the wall, the low-speed motor starts up. The operator provides multiple switching pulses for 1-2 seconds if a speed regulator is not available to guarantee that the drill’s cutting edge penetrates deeply into the concrete surface.
Simultaneously, the tool’s and the concrete wall’s perpendicular axes are observed. After that, drilling is done with the impact mode activated. The force applied to the drill and the drill’s rotation speed determine the cutting speed.
It is advised to remove the drill from the channel to clear chips and dust before drilling deep holes. It is acceptable to use a metal drill when dealing with metal reinforcement; in most situations, the impact force of the drill in the hammer drill is sufficient to break a rod composed of soft structural steel.
Tips for performing work
It is advised that you become familiar with the following helpful guidelines before drilling a hole in concrete:
- If a plastic dowel is supposed to be installed in the hole, the length of the channel should exceed the length of the dowel by 10-15 mm. The gap is used to collect concrete chips from the walls of the hole.
- When starting drilling, it is necessary to set the minimum speed. The drill does not move along the surface, which allows you to drill holes in accordance with the markings. As the drill goes deeper, it is necessary to increase the speed and increase the load on the drill or hammer drill.
- If the drill slips in the chuck (due to wear or damage to the cams), it is necessary to replace the clamping device. Using a drill with a damaged chuck leads to misalignment of the equipment parts and a decrease in the quality of the work performed.

If done correctly, making holes in concrete using drilling, cutting, or punching techniques can be a simple task. With minimal effort and the correct tools—like a drill or hammer drill—you can accomplish precise results by following a step-by-step plan. Making sure your project is safe and successful requires careful planning and process understanding.
First, make sure you have the right tool for the job. A hammer drill or other specialized cutting tool might be required for larger or deeper cuts than what a standard drill can handle. Use the appropriate drill bit or cutting attachment made specifically for concrete to prevent equipment damage and guarantee precise cuts.
When you’re ready to start, use chalk or a pencil to mark where your holes will be. If at all possible, secure the concrete surface before starting the low-speed drill bit to make the guide hole. As necessary, gradually increase the pressure and speed while taking care to maintain the drill’s stability and refrain from using excessive force. This will guarantee a smooth finish and lessen the chance of cracks.
Always remember to exercise caution when performing any task. Put on safety equipment, such as gloves and goggles, to shield yourself from dust and debris. Take frequent breaks and maintain a well-ventilated work area to prevent overusing the tools or yourself.
You can effectively drill holes in concrete for any project by following these instructions and taking the appropriate safety measures. Having the right tools and knowledge of the procedure will make any task—installing fixtures, running cables, or making structural changes—easier and more efficient. Enjoy your drilling!
