Corded angle grinders - what do you need to know before buying?
Angle grinders are versatile tools used on construction sites and in professional workshops, as well as for home projects. With the ability to cut, grind and polish a variety of materials such as metal, concrete, brick and ceramic and stoneware, they have become indispensable in many industries.
There are many versions of angle grinders on the market, with different functions and needs. Choosing the right model will certainly be crucial to the efficiency of the work. The main decision you will face when choosing a grinder is powersource. Cordless grinders, which are becoming increasingly popular today, are a convenient and handy solution, but it is corded machines that still win out in long jobs where there is no room for downtime or prolonged drops in efficiency due to the need to recharge the batteries.
Corded angle grinder - why is it worth it?
Choosing a corded model of an angle grinder brings with it several important advantages that can affect your working efficiency and comfort. Here are a few reasons why you should consider this choice:
Unlimited working time.
Unlike cordless models, corded angle grinders run continuously as long as they are plugged in. For contractors carrying out large-scale jobs such as sanding large areas, the uninterrupted availability of power and the lack of need to recharge the batteries eliminates the hassle of interruptions associated with battery charging.
Constant power.
Corded models are characterised by a stable, consistent power source, which translates into consistent performance. They can be relied on in the context of tasks requiring intensive and continuous loading.
Greater motor power.
Thanks to the constant power supply, corded grinders also offer more power, which translates into more effective and efficient operation, especially for heavier and precise tasks. This makes them more effective for tasks that require a high degree of precision, strength and speed, such as cutting hard materials such as metal or stone.
Lighter design.
With no need for a battery, corded grinders also tend to be lighter than their battery-powered counterparts. This translates into less fatigue for the operator during long working sessions and therefore has a positive impact on the efficiency and precision of the work performed.
Lower operating costs.
The purchase and operation of a corded grinder typically generates lower costs compared to cordless models, which require additional batteries and chargers.
Wide range of applications.
Thanks to their power and stability, corded angle grinders are ideal for professional workshops, construction sites and intensive renovation work where robustness and reliability are required.
Affordability.
Corded tools tend to be more affordable, which can be an important factor when buying more equipment for a construction team.
When deciding on a corded angle grinder, it is worth bearing in mind its limitations. Working in locations away from power sources requires the use of extension cords, making it difficult to move around the construction site. Cables can restrict mobility and force you to frequently switch between sockets, which in turn can slow down the pace of work. Additionally, working outdoors on rainy days can involve the risk of breakdown due to moisture, which is not as much of a risk with cordless tools.
An alternative to corded tools is the cordless angle grinder. It provides full mobility, allowing you to work in hard-to-reach areas. The absence of a cable eliminates the risk of tripping and increases the convenience of use, especially in areas with limited access to electricity.

Rotational speed.
The rotational speed (expressed in revolutions per minute, RPM) affects the efficiency of the grinder. Standard models reach speeds between 6,000 and 12,000 RPM. A high RPM works well for jobs that require fast grinding and cutting, such as cutting metal or grinding steel. The variable speed control of the angle grinder allows you to adjust the speed to suit the type of work. The speed setting is useful for more delicate materials, such as wood or aluminium, where too high a speed could cause overheating or damage to the material. - 4
Angle grinder anti-vibration system.
Vibration reduction systems are a key aspect that affects user comfort, especially during prolonged work. For building contractors who have to use a grinder for many hours, models equipped with additional vibration-dampening mechanisms will be less tiring and safer for health. Minimising vibration reduces hand fatigue and lowers the risk of occupational diseases such as vibration syndrome. - 5
