Total number of nozzles
The total number of working attachments supplied with the tool.
The abundance of attachments allows the machine to be used with various materials and for various types of work. At the same time, this parameter significantly affects the cost. Therefore, when choosing, you need to proceed from how important a variety of possibilities is for you - so as not to overpay for extra nozzles that turned out to be useless in fact.
Note that this item is indicated only for engravers (see "Device") - for models of other types, specific types of nozzles are given in the corresponding item (see below).
Additional handle
The presence of
an additional handle in the design or delivery set of the tool (it can be either built-in or removable).
This handle makes it easier to hold the tool with two hands, which is important when processing hard materials that require significant effort — or in delicate work, where precision and maximum control are important. Note that, as a standard, it is done based on right-handed users, however, many tools allow you to change the location of the handle, for the convenience of "left-handed" work.
Tripod
A
tripod is included with the instrument.
This function is found mainly among rotary engravers (see "Device"). The tripod is designed to hang the tool on it when working with a flexible shaft (see "Attachments") — usually, this is more convenient than simply placing the machine on a table or other surface. Without a tripod, this would have to use carnations, hooks or other similar devices — and they are far from being available everywhere, and they do not always provide reliable placement.
Weight
The weight of the tool can be indicated according to different rules: some manufacturers take into account only the body without a nozzle, others — with a standard working nozzle, for multi-tools (see "Device") the weight of the main unit without a replaceable head, etc. can be indicated. These points are usually specified in the specifications or detailed documentation.
In the case of a power tool, weight has a dual meaning. On the one hand, the smaller it is, the easier it is to hold the unit in your hands during long work and the more convenient it is to carry out fine, accurate processing. On the other hand, a light tool is less stable and has an increased tendency to jerk, which is important under difficult conditions and hard materials.
