Comparison Skil 1613 AA F0151613AA vs Hitachi UM 16VST

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.

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.

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.

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.

— 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.

Note that the above list is not complete — other additional items may be supplied with modern tools

This refers to the weight of a fully assembled and ready-to-use construction mixer or drill mixer. What you need to pay attention to here is that the small weight of the device is not always its advantage. On the one hand, during operation, the tool has to be kept on weight, most often in a vertical position, which is very tiring. But on the other hand, heavy models are less susceptible to vibration, it is easier to fix them in one position.
