Difference Angle Grinder From Angle Grinder

How to choose a sander?

Before proceeding with the purchase, you need to decide what specific device you need and what functions it should perform. The tape machine is designed to work in place of a planer. That is, the work of the tool is a rough roughing of paint and leveling the surface. For vibration, work on wood, plastic and metal is more common. Such a machine produces high-quality cleaning and polishing of the material. The orbital sander is designed to work with convex and curved surfaces. Thus, before purchasing this kind of tool, it is important to decide on what surface you will work on and what requirements the electrical appliance must meet.

Types of grinders

Belt sander. It is a tool where the surface is sanded unidirectionally, using a sanding belt, which is located on the rollers provided for rotation. This type of tool is suitable for polishing large surfaces.

Belt sander

Vibration sander. This type of machine is also called a surface grinder. It is a flat-bottomed instrument, hence the name. The surface is sanded by the reciprocating motion of the sandpaper. It is this action that is vibrational in nature. This type of machine also has vacuum cleaners for collecting construction dust.

Vibration sander

To work on ledges and corners, there is another type of vibration-type machines, this is a delta sander. The sole of this type of tool has a triangular shape, which allows you to work in hard-to-reach places.

Eccentric sander. This variety is commonly called orbital. The name, again, was formed from the appearance of the sanding sole. It resembles an orbit or, more simply, a circle.

Eccentric sander

Angle grinder. This type of machine rotates around its axis. In addition to grinding, the angle grinder can cut metal, concrete and other materials.

Angle grinder

Polishing sander. The function of this tool is to polish metal and painted surfaces.

Polishing sander

Brush sander. The brush functions as a grinder, rotating along its axis.

Popular functions of angle grinder

  1. Function “Soft start”. Devices that have this function are very convenient to use, due to the fact that the device starts to work at lower speeds, gradually gaining power.
  2. Balancing. This feature is present only on the highest quality models.
  3. The very shutdown of the brushes. This function is also present only on high quality devices. The brushes automatically turn off in the event of a power outage.

Angle grinder and grinder. How they differ

Angle grinder is the colloquial name for a power tool designed for abrasive processing of metal or other types of material.

The most important parameter when choosing an angle grinder is disk size. The diameter of the disc determines the depth to which the device will cut the material. Also, do not forget that during operation, the disc is gradually erased and becomes smaller, thereby reducing the cutting depth.

A sander is a type of power tool for grinding and polishing surfaces of various materials, such as plastic, metal, wood.

Many types of grinding machines have the function of collecting sawdust, shavings, in a word, waste from the work performed. The vacuum cleaner can be either built-in or additionally connected.

Comparative analysis of electrical appliances

As you can see from the above description of electrical appliances, the functions of these tools identical by 98%. Both devices are used for cutting, grinding and polishing materials from metal, wood, plastic and other materials.

Sanders have a wider range of separation of work areas (flat surface, angular). Also, many models have a vacuum cleaner function, which is not the case for an angle grinder.

Often, an angle grinder is used as a tool for cutting various materials, and a grinder is more intended for cleaning surfaces and subsequent polishing.

Types of grinders

In addition to the fact that the angle grinder is divided into household and professional, the angle grinder is distinguished by the principle of operation. The only difference between the two is what is inside and the power source. Given these features, you can choose the appropriate option for specific operating conditions.

What to look for when choosing

To choose the right option for an angle grinder for home use, you need to decide not only on the type of tool, but also look at other characteristics.

How to choose an angle grinder for home use. 10 main criteria

Need a quality angle grinder for home use? How to find a good option for your home and not overpay, the article suggests.


Similar in structure to mains tools, with the exception of the large battery compartment. As a rule, it is located at the end of the handle.

The cordless angle grinder is especially handy where there is no mains supply. Such a tool is useful for outdoor work.

The device can be selected for handling materials in buildings that are not connected to electricity or have few outlets. In addition, due to the fact that the user does not get in the way of wires, the device is convenient when you need to work under the ceiling.

In addition to the obvious advantages over models that are powered from the mains, such an angle grinder is somewhat inferior to them. Firstly, they are more expensive, and secondly, the operating time of the device is limited by the battery capacity. In addition, devices are usually only compatible with small diameter discs.

Mains powered

Network. Some of the most popular power tool options. In this case, the angle grinder is powered by an outlet.


  1. Variety in terms of dimensions, capacities allows you to supply abrasive wheels of all sizes;
  2. Low, in comparison with other types of angle grinder, price;
  3. Less weight than other models;
  4. Many attachments for different jobs.

Possible complaints:

  • If the electricity is turned off, it will not work;
  • The user’s movement is limited by the length of the wire;
  • Failures with voltage drops.

For grinders designed to work with large discs, the rotation speed is 7-9 thousand revolutions per minute. For devices with smaller circles, this parameter is higher. About 12 thousand.

It is worth taking into account: the characteristic is indicated by the manufacturer, taking into account the idle speed. In practice, the disc spins a little slower.

Some home angle grinders, like the GL-125S, have a speed control. This option is worth choosing if you want to adjust the speed yourself.

The main features of small grinders

The small angle grinder has its own characteristics that make it an indispensable tool in solving a number of construction and repair tasks:

  1. It is lightweight. This feature allows you to work on weight for a long time without getting tired.
  2. It has a compact size, which allows the device to work in places where it is difficult to approach with more bulky equipment.
  3. You can work without using an additional handle: thanks to the small diameter of the housing, the small angle grinder can be gripped with just one hand and the surface can be cleaned. It is very convenient if you have to hold on with one hand and work with the other.
  4. There are battery-type devices, which gives even more freedom in the use of the tool.
  5. Small angle grinders have little power. This eliminates the possibility of strong vibration during operation and makes it possible to carry out more accurate processing.

Main Purpose of Mini Angle Grinder

  1. Cut-off operations. Angle grinder can cut steel, other metal, concrete, asbestos, slate, ceramic tiles.
  2. Roughing operations. The small device is convenient for cleaning surfaces from rust, oxides, old paint on metal structures and wood.
  3. Slitting operations. You can make grooves for electric wires and other communications, remove old grout from the seams of ceramic tiles.
  4. Grinding operations. Angle grinder can grind and polish surfaces.
  5. Sharpening operations. Small angle grinder ideal for sharpening household cutting and stabbing tools.

Mini and micro angle grinder

The design of the mini angle grinder is practically no different from ordinary grinders: it has the same longitudinal arrangement of the cutting disc. The obvious difference between the device is the absence of a pronounced main handle (in a small model, the body of the device itself acts as it) and the small size of the body itself. Other signs that clearly indicate that we have a small angle grinder in front of us are as follows:

  • The ability to put a cutting disc of 125 mm. No more;
  • Power consumption of electricity does not exceed 1 kW.

Among the small grinders, a separate category can be distinguished. These are microdevices. They are even more miniature, the design has a transverse arrangement of the working body. In such devices, as a rule, there is no reduction gear and the rotation speed of the disk corresponds to the number of engine revolutions. This is justified by the fact that the device is not designed for heavy loads and more serves as a grinding equipment.

Review of small grinders for the home craftsman

The mini-angle grinder differs from a conventional angle grinder in that it has a compact size and light weight, which makes it an indispensable tool for working in hard-to-reach places, confined spaces, while weight, while you can perform many construction and repair operations.

Angle machines for grinding operations (angle grinder) come in different sizes. The larger the angle grinder, the larger the diameter of the cut-off wheel you can put on it. But dimensional devices are also heavy. It is difficult to work with such a tool at a height and it is impossible to crawl into hard-to-reach places. Another thing is a mini-angle grinder: it is lightweight, convenient to use, more economical, and most importantly, it can carry out the same list of works as a large one.

Among the smallest examples there are models with a cutting wheel of up to 70 mm in diameter. Even jewelry operations can be performed with such miniature equipment.

When purchasing any model of an angle grinder, both large and small, do not forget that they are all dangerous tools with which you need to be extremely careful: here negligence can lead to irreparable!
