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.
Spindle internal thread
The type of internal thread of the spindle determines the possibility of using one or another nozzle with the tool. Also pay attention to the "Type of cartridge" (see below). Most construction mixers today have a metric thread on the spindle for attaching nozzles:
M12,
M14,
M18,
M20,
M24, but there are also spindles with
⅝” inch internal threads.
Chuck type
The chuck type determines the mechanism by which the attachment is attached to the construction mixer and by which the energy of the tool is transferred to the work area. Nozzles with different types of fastening are not interchangeable.
—
Key. One of the simplest and most reliable solutions, well suited for tough jobs. The nozzle is fixed in the cartridge using a special key, and after work it is removed with the same key that is included in the package. Even if you fill the junction with glue, the nozzle is still easy to remove with a wrench and improvised tools. But this process can become problematic if you lose the key. Due to the great popularity of this mechanism, the user can use nozzles from different manufacturers.
—
Quick release. Models of this type use the FastFix (QuickFix) quick-clamping clamp, due to which the drill is fastened without the use of additional tools. This allows you to quickly change the tooling without much effort, the user does not need to resort to the help of any improvised tools, hand effort is enough. A simple and convenient solution, but some experts consider it not the best option for heavy work.
—
Morse taper and key. The attachment of the nozzle of these tools has a special tapered shank that is inserted into the tapered hole of the spindle. The main advantage is high centering accuracy. Most often used in
...mixer drills, but not very popular.Weight
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.
