Angle grinders (grinders)

Angle grinders (grinders): basic properties and tips for choosing

During finishing work, one of the most demanding stages is to bring the surface to a flawless smoothness. The surfaces to be processed can be concrete, wood, brick, plastic, metal or stone. And to process them, nail technicians may need to perform rough grinding or delicate polishing. An angle grinder can easily handle both tasks.

What is an angle grinder and what is it for?

An angle grinder (grinder) is a very popular tool among professionals. The versatility of this equipment is ensured by the possibility of using additional attachments. Depending on the type and design of the power tool, different tasks can be performed. As a rule, an angle grinder is used to perform the following types of work:

• Sanding, particularly on vehicle bodies. Abrasive discs can be used for this purpose.
• Cleaning surfaces during furniture restoration, removing rust or old paintwork, levelling walls after puttying (special cleaning brushes are used).
• Cutting various materials (cutting discs or diamond end mills are used).
• Polishing of surfaces after finishing with varnish or paint (polishing nozzles are used).
• Strobing the wall for further wiring.

This type of electrical equipment remains an indispensable assistant to professionals, helping them to perform a wide range of work.

What are the main characteristics of angle grinders?

Acordless grinder or angle grinder powered by the mains remains a very effective piece of equipment with a wide range of applications. The right choice of this equipment affects the quality of the result, the speed of work and other important parameters. The main criteria for selecting a power tool are its engine power, type and technical characteristics, and the availability of additional features.

When choosing an angle grinder (grinder), be sure to pay attention to

• Power. The higher the power of the power unit, the greater the range of work possible. Modern manufacturers offer models with power in the 600-2500 W range. It is also worth paying attention to the diameter of the nozzles that will be used. For example, a 750 W motor is enough to work with a 125 mm diameter wheel, and a 2200 W motor is sufficient for a 230 mm disc.
• Engine speed. The larger the diameter of the nozzle, the lower the engine speed should be. When installing the discs, make sure that the technical parameters specified in the instructions are met. An angle grinder with a speed controller may be the best solution.
• Allowable disc diameter. An important characteristic when choosing a power tool is the maximum diameter of the disc that can be mounted on the grinder. The standard size of the nozzle is 125-230 mm. Moreover, it is allowed to install discs with a diameter smaller than that specified in the instructions. It should be emphasised that the use of discs with a diameter larger than the maximum permissible diameter is strictly prohibited.
• Type of engine. Modern manufacturers offer two types of equipment: corded and cordless. Cordless angle grinders are typically rated at around 800 W. They are self-contained and can work continuously for a long time. The advantages of cordless machines include their compact size, light weight, motor reliability, high-quality protection system and soft start function. Corded grinders are powered by the mains. The advantage of this tool is its stable engine power regardless of the duration of operation. However, in the event of power surges, the angle grinder may operate erratically.

In addition to the parameters described above, you should also pay attention to the type of body and weight of the tool. These parameters affect the ease of use of the grinder.

Types of angle grinders: what are they and how do they differ?

Modern manufacturers, whose products are presented in the VADA online store, for example, Makita grinder, offer different types of angle grinders. The most popular are:

• Electric grinders. They are more affordable and have a stable engine power. However, they require a stable power supply to operate, which can often lead to some inconvenience.
• Cordless angle grinders. This electrical equipment is characterised by autonomous operation, mobility, light weight and a high-quality protection system.
• An angle grinder with a speed control option. Thanks to this feature, craftsmen will be able to perform a variety of jobs, such as cutting thin tin. It is in this case that it is necessary to set the minimum speed of the wheel to prevent the cut from melting. Such models are equipped with an automatic engine shutdown function when critical parameters are reached.
• Angle grinder 125. This equipment is characterised by lower power, low weight and compact dimensions. It can be used with a disc diameter of up to 125 mm, for example, for cutting thin sheet metal, cutting rolled sections of small thickness, etc.
• Engraver angle grinder. These models are ideal for craftsmen who require maximum accuracy.

You can buy such models in the VADA online store at affordable prices.

What features should a cordless grinder have?

When choosing an angle grinder, we recommend that you pay attention to the mandatory features that must be present in the tool. These include speed control, a soft-start system, protection against disc jamming, overload and dust, anti-vibration capability, and the ability to replace consumables.
