Additional handle. Separate handle for a second hand. Theoretically, such equipment could make the instrument more comfortable to hold with two hands. However, in fact, the absence of an additional handle is often not critical: many tools without it are either intended to be held in one hand (like some straight grinders, see "Type"), or have other adaptations for a second hand (for example, a ledge on the body). So to answer the question of whether you need an additional handle, you need to take into account the type and size of the grinder, as well as the features of the planned work. Also note that by default such a handle is designed for right-handers, and the possibility of its use with left-handed holding should be specified separately.

Charger(charger). A device for charging the battery in a grinder with the appropriate type of power supply (see "Power supply"). Also in this paragraph, a specific model of the charger is usually specified. In itself, the presence of a "charger" in the kit eliminates the need to look for and buy it separately; at the same time, such a charger is optimally suited to at least the “native” battery, and often also to other compatible batteries. And data on the model will be useful, first of all, in case the complete charger is lost or fails and you have to buy the same or similar one instead. In addition, knowing the charger model, you can find detailed data abo
...ut it and evaluate its characteristics and features (compatibility with various batteries, additional functions, etc.). At the same time , the “without charger” package is also very popular — see below for more on it.
— No charger. This feature is indicated exclusively for battery models (cars with other types of power supply — see "Power Source" — by definition do not have a charger, there is no need to specify this point for them). The meaning of this configuration is that modern grinders most often use standard batteries, which are also suitable for other power tools of the same brand and are designed, respectively, for standard “chargers”. Thus, if the "household" already has a battery tool, then the charger for it may be suitable for the grinder, you will not need to overpay for the second copy of the charger. And even if the charger is not available, usually, it can be purchased separately without much difficulty (moreover, some tools also allow you to choose the most suitable model of such a device from several options).
— Case / bag included. The presence of a case or bag for storing and transporting the tool. The case is a suitcase and is made of durable material, usually there is a place not only for the machine itself, but also for working attachments and other additional accessories. The bag is soft, which allows it to be compactly folded when there is no need for it. Check the availability of a case or bag immediately before buying.
— Dust collector. Container for collecting dust and other contaminants that occur during operation. See "Advanced — Connecting the dust box" for details.
— Barbell. A long rod significantly expands the "radius" of the tool: with such equipment, you can reach a great height, process a large area without rearranging the platform or other stand, etc. Such features are relevant primarily when processing walls, so the vast majority of grinders with rods in the kit are wall grinders(see "Type").Battery in set
Most modern power tools use replaceable batteries, and then this paragraph indicates the number of such batteries. It is worth saying that the most popular version of this configuration nowadays is
2 batteries. It is relatively inexpensive and at the same time allows you to minimize, if not eliminate interruptions in work: while one battery is in use, the second can be charged, and when the charge is exhausted, the roles change. In this regard
, single battery kits are not particularly common: they are mainly entry-level tools that are not designed for long-term use and allow interruptions to recharge the battery.
In addition, quite a few modern cordless tools come in a configuration colloquially known as a “carcass” — namely,
no batteries at all. This option is relevant mainly for two cases: if the user wants to choose a power source separately, at his own discretion, or if such a source is already on the farm. Regarding the second option, it is worth noting that many large manufacturers use universal batteries suitable for different types of branded power tools. So a battery, for example, from a previously purchased jigsaw or drill may well be compatible with a grinder of the same company.
As for
non-removable batteries, this is a rather rare and specific option. Such tools are as compact as possible, but the batteries t
...hemselves cannot be quickly changed — so you will inevitably have to take breaks for charging during work. Therefore, this method of supply is typical for low-power instruments. In them, small size is more important than a long period of continuous operation, in addition, a low capacity allows you to achieve good battery life even with small sizes (and, accordingly, capacity) of batteries.Charging time
The time required to fully (from zero to 100%) charge the battery in the battery device (see "Power supply"); this refers to the complete battery and standard charger. The shorter this time, the shorter the breaks will have to be done for recharging; however, higher capacity batteries inevitably take longer to charge than smaller ones. This can be compensated by the use of fast charging technologies, but they, in turn, affect the cost of the tool.
