Product type
— Mixer. Construction tool for mixing various building mixtures: paint, glue, plaster, mortar, etc. Unlike drill mixers (see below), the functionality of these devices is strictly limited to mixing viscous solutions. But at the same time they are much more powerful, reliable and boast high torque. They can be in demand both in construction and in the household.

Drill mixer. This tool combines the functionality of a construction mixer and a classic drill in one relatively compact body, making it a more versatile solution for home use. Usually, all models of this type are equipped with a chuck and support the possibility of installing a mixing nozzle or equipment for drilling holes in wood and other materials. Lighter and more convenient to use when compared with the mixers described above, but at the same time inferior to them in terms of power.
Power consumption
The power consumed by the construction mixer (see "Device") during operation.
High power provides the device with high performance — such a model can easily cope with complex tasks, such as mixing a large volume of mixture at a time or while working with heavy fillers, such as crushed stone. On the other hand, high power affects the power consumption of the device, its weight, dimensions and cost. It makes little sense to purchase a powerful model if you select a tool for domestic use from time to time.
Rotation speed
The rotation speed of the nozzle or mixing container provided by a plaster mixers.
High rotation speed devices work best with paints, varnishes and glues.
Low rotation speed models do a good job of preparing thick mixtures. Many modern plaster mixers and mixer-drills support the ability to adjust the speed (see "Features"), which allows user to choose the most optimal mode for a particular mixture. Powerful tools especially need a rotation under heavy load support system.
Max. torque
The
higher the torque, the better the tool handles viscous masses, where special force is required to turn the mixing nozzle. It is measured in Newtons per metre (N/m). Note that with an increase in the speed of rotation (see "Number of revolutions"), the torque decreases, and vice versa.
Max. mixing paddle diameter
The vast majority of attachments for construction mixers have a standard size in length, usually 600 mm. But their diameter may differ, its maximum size is limited by the manufacturer, which must be considered when choosing. The indicator depends on the technical characteristics of the tool. The most popular sizes are
120mm,
140mm and
160mm nozzles. The larger the diameter of the auger, the easier it can cope with a large volume of mixed mixture.
Max. wood drilling diameter
Refers to models that the user can also use as a conventional drill for drilling wood or metal. The parameter characterizes the largest diameter of holes that can be made using a tool. Here it should be taken into account that some modern mixers allow you to install drills of a much larger diameter than indicated by the manufacturer, and, theoretically, make a larger hole. But the larger the diameter, the higher the resistance of the material and, accordingly, the power of the device should be large. Using the tool on off-design loads is fraught with breakdowns.
Max. steel drilling diameter
The maximum diameter of a hole that can be made with a particular construction mixer or mixer drill when drilling steel. See "Maximum wood drilling diameter.
Functions
—
Soft start. This function allows you to avoid a sharp start of the engine at the beginning of work, which, on the one hand, allows you to avoid overloads on the power supply network, and on the other hand, splashing of building mixtures.
—
Speed controller. The ability to adjust the speed of rotation of the nozzle of the working tool will be very useful for working with mixtures of different consistency. As you know, for effective mixing of liquid materials, a high speed is required, and for viscous materials, a lower speed, but a higher torque.
—
Maintain momentum. With the help of special sensors, the speed control system monitors changes in load and, depending on this, increases or decreases the speed of the nozzle, thus maintaining the speed set by the user, regardless of the load. This ensures more efficient and better mixing and extends the life of the device.
—
Power button lock. Locking the power button when the tool is off allows you to avoid accidental start in abnormal mode, which increases the safety of the device. And vice versa: locking when the tool is on eliminates the need to constantly keep your finger on the power button, which is very convenient, especially during long work.
—
Electronic engine protection. The system provides automatic shut
...down of the engine in case of overheating, jamming of the nozzle, or simply in case of a critical increase in load, which helps to avoid tool failure and extend its service life.
— Brushless motor. The presence of a brushless (brushless) motor in an electric tool. Such motors are noticeably superior to traditional collector motors in terms of efficiency, which can significantly reduce energy consumption without sacrificing power; this is especially important for cordless tools (see "Power Source"), where this feature is predominantly found. In addition, brushless motors are quieter and produce virtually no sparks during operation, making them perfect for working in high fire hazard environments. Their main disadvantages are traditional — the complexity of the design and high price.In box
— Charger. A device for charging the batteries used in the instrument with the appropriate power supply. For models supplied with such a device, the specefications may specify the charger model. This information can be useful not only for finding a spare or replacement charger, but also in case when there are other battery tools and/or batteries for them in the household. The fact is that many manufacturers nowadays use universal batteries compatible with a whole set of tools from the same brand; so, for example, a charger for a mixer may be quite suitable for a battery grinder from the same manufacturer.
On the other hand, a lot of modern battery tools are supplied without a charger at all. This option will be optimal, first of all, if a compatible charger is already available, and there is simply no need to overpay for a second device. In addition, the lack of a charger will be appreciated by those who want to choose this accessory separately, without relying on the manufacturer's decision.
—
D-shaped handle. An additional handle in the shape of the letter D is provided for in the design of the device. It is found mainly in small and relatively light mixer drills, which can be used to create holes in wood or metal. Allows user to fix the position of the tool more firmly during operation.
—
Hand protection. A small, usually metal frame is provided around the handle of the tool, wh
...ich helps to avoids damage to the user's hands during operation. It is used mainly in powerful, performant construction mixers. It is not found in small drill mixers, since it is practically useless there.
— Mixing attachment. The tool is initially equipped with a mixing attachment. Its availability, on the one hand, allows you to get to work immediately after purchase, instead of looking for and buying an attachment separately, and on the other — not to worry about the compatibility of the tool and the attachment.
— Mixing container. The equipment of this tool initially provides a special container for mixing building mortar and other mixtures. Usually we are talking about professional stationary mixers, primarily designed to perform large-scale construction work.
— Case/pouch. Some construction mixers are equipped with special cases or covers for the convenience of storing and carrying both the device itself and its components, such as attachments or a key.
