Revolution in making grooves - comparison of methods
Traditional chiseling with a hammer drill or hammer and chisel has been the standard in construction for decades. However, technological progress has made the wall chaser offer significant advantages in most applications.
Efficiency and precision of work
The greatest advantage of the wall chaser is the dramatic difference in efficiency. While a hammer drill requires tedious chiseling of every centimeter of concrete, the wall chaser cuts the material evenly and without vibrations. From our experience in technical consulting, we know that the time to make grooves can be reduced by several times, especially for larger installation projects.
Precision of execution is another key aspect. The wall chaser allows for the creation of perfectly straight grooves of a specified depth and width. In practice, this means better fitting of installations and less consumption of finishing materials during later plastering work.
Minimization of structural damage
Traditional chiseling often leads to cracking plaster, breaking bricks, or damaging wall structures. The wall chaser eliminates these problems thanks to even cutting without vibrations. From our clients' experience, we know that this is particularly important when working in residential buildings, where maintaining aesthetics and structural integrity is crucial.
Technical parameters determining capabilities
When choosing a wall chaser from our offer, it is worth paying attention to key parameters that determine the possibilities of replacing traditional methods.
| Parameter | Wall chaser for home use | Professional wall chaser |
|---|---|---|
| Motor power | 1400-1600W | 1800-2400W |
| Cutting depth | up to 35mm | up to 65mm |
| Disc diameter | 125-150mm | 150-180mm |
| Rotational speed | 8000-10000 rpm | 4000-9000 rpm |
Diamond disc system - the heart of the wall chaser
The effectiveness of the wall chaser in replacing traditional chiseling largely depends on the quality of diamond discs. In our assortment, you will find discs adapted to various materials - from standard concrete to reinforced concrete or ceramic materials.
Professional wall chasers use a system of two parallel discs, allowing for the creation of a finished groove without the need for additional chiseling. The latest models, such as DeWALT DCG200T2 from our offer, provide even greater versatility thanks to battery power.
Limitations and cases where traditional methods remain relevant
Despite the obvious advantages, the wall chaser cannot always fully replace traditional chiseling methods. Based on our experience in technical consulting, we distinguish several situations where the classic approach may prove to be more practical.
Technical limitations of the wall chaser
Large diameters of installations - with ventilation pipes Ø125mm and larger, the wall chaser may prove insufficient
- Irregular shapes - making branches or connections at an angle often requires finishing work with traditional methods
- Very hard materials - some types of high-strength concrete may require the use of impact hammers
- Demolition work - when dismantling larger sections of walls, traditional methods remain more effective
Economic aspect and availability
The cost of purchasing a professional wall chaser can be a barrier for small installation companies. In such cases, a hybrid approach - using the wall chaser for main installation routes and traditional methods for finishing work - may prove to be an optimal solution.
Safety and working conditions
One of the greatest advantages of the wall chaser is the significant improvement in working conditions. Modern models from our offer are equipped with dust extraction systems that can be connected to industrial vacuum cleaners. This practically eliminates the problem of concrete dust - the main health hazard with traditional chiseling methods.
Additionally, the wall chaser generates significantly less noise than a hammer drill, which is important when working in residential buildings. Reduced vibrations also translate into less fatigue for the operator during prolonged work.
Frequently asked questions
1. Will the wall chaser completely replace the hammer drill in electrical installations?
In most cases, yes - the wall chaser offers precision and efficiency unavailable to traditional methods. From our experience, 80-90% of wall chaser work can be done exclusively with the wall chaser. The hammer drill remains useful only for finishing work in hard-to-reach places and with larger installation diameters.
2. What power of the wall chaser is sufficient for working with concrete?
For standard concrete, a power of 1400-1600W is sufficient, but for reinforced concrete, we recommend a minimum of 1800W. In our assortment, there are models with power up to 2400W, which can handle the hardest construction materials. The quality of the diamond discs is also important - they largely determine cutting efficiency.
3. Can the wall chaser be used without a dust extraction system?
We do not recommend working without dust extraction for safety and comfort reasons. Concrete dust is harmful to the respiratory system, and its amount when working with a wall chaser is significant. All our wall chasers have the option to connect to an industrial vacuum cleaner - this is an investment in health and work efficiency.
4. What is the maximum depth of a groove that can be made with a wall chaser?
Standard wall chasers from our offer allow cutting to a depth of 35-40mm, while professional models can go up to 65mm. The depth depends on the diameter of the discs used - 150mm discs allow for deeper cuts than 125mm. For most electrical and hydraulic installations, these parameters are 
sufficient.
5. Will the wall chaser work for renovating old buildings?
Yes, especially in old buildings, the wall chaser prevents structural damage. Old walls are often sensitive to vibrations from hammer drills, while the wall chaser operates evenly without vibrations. This minimizes the risk of plaster cracks or damage to adjacent structural elements, which is crucial in historic buildings.
The future of groove technology - direction of development
Based on our market observations and contacts with manufacturers, we can state that the wall chaser is systematically replacing traditional chiseling methods. Modern battery models, such as the solutions available in our offer from DeWALT and other renowned brands, already offer mobility comparable to traditional tools, with significantly better working parameters.
The development of diamond disc technology and dust extraction systems makes the wall chaser the tool of choice for professional installers. At Onninen, we observe a growing interest in complete wall chaser sets that include everything needed for effective work - from the tool itself to professional tips for making grooves.
Our team of experts recommends investing in a wall chaser to all installers who value precision, efficiency, and comfort at work. In our branches across Poland, we provide not only access to the best equipment but also professional advice on selecting optimal solutions for specific applications.
