Comparison DeWALT DCG405P2 vs DeWALT DCG414T2

The ability to lock the power button prevents accidental presses. Accidental Activation Protection allows safely transporting the switched-off tool from place to place during work breaks without fear of unintentionally turning it on. This feature is also handy when there are small children around. In some models, protection can also be activated when the power is cut off (for example, network failures) — thanks to this, when the power is restored (which can occur at the most unexpected moment), the tool will not start operating without a user command.

— Additional Handle. A separate handle for the second hand. In theory, such equipment may make the tool more comfortable to hold with both hands. However, in practice, the absence of an additional handle is often not critical: many tools without it are either designed for one-handed use (like some straight grinders, see "Type") or have other attachments for the second hand (such as a protrusion on the body). So, to answer whether you need an additional handle, you should consider the type and size of the grinder, as well as the specifics of the intended projects. Note also that by default, such a handle is designed for right-handed use, and the possibility of using it in left-handed operation needs to be clarified separately.

— 3-Position Additional Handle. An additional handle installed on a detachable mount and having three installation options: on the left (traditional option for right-handed use), on the right (for left-handed use), and on top (for specific cases — situations when you need to periodically change grip, work in hard-to-reach places, etc.). This function provides extended possibilities for tool customization according to personal preferences. It is mainly found in angular models (see "Type").

— Charger (C). A device for charging the battery in a grinder with the appropriate power type (see "Power Source"). This section usually specifies...the specific model of the charger. Having a "charger" included relieves you from the need to search and purchase it separately; moreover, such a charger is optimally suited at least to the "native" battery, and often to other compatible batteries. The details on the model will be useful primarily in case the included charger is lost or fails, and you have to buy the same or a similar one instead. Moreover, knowing the model of the charger allows you to find detailed data about it and assess the characteristics and features (compatibility with various batteries, additional functions, etc.). At the same time, the configuration "without charger" is also quite popular — see below.

— Without Charger. This feature is indicated exclusively for battery models (machines with other power types — see "Power Source" — by definition do not have a charger, so this point does not need to be clarified for them). The meaning of such a configuration is that modern grinders most often use standard batteries, which also fit other power tools of the same brand and are thus designed for standard "chargers." Thus, if there is already a battery tool "in the household" — the charger for it may turn out to be suitable for the grinder, and you will not need to pay extra for a second copy of the charger. And even if there is no charger available — it can usually be purchased separately without much difficulty (and some tools even 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 in the supply kit. The case is a suitcase made of durable material and usually has space not only for the grinder itself but also for working tips and other additional accessories. The bag is soft, allowing it to be compactly folded when not needed. Check the availability of a case or bag directly before purchase.

— Dust Collector. A container for collecting dust and other contaminants generated during work. See "Additional — Dust Collector Connection" for more details.

— Extension Pole. A long pole significantly expands the "radius of operation" of the tool: with such equipment, you can reach greater heights, process a large area without moving the platform or other stand, etc. Such capabilities are mainly relevant when processing walls, so the vast majority of grinders with extension poles included pertain to wall sanders (see "Type").

The name of the battery platform supported by the instrument.

The battery platform is a battery standard used to keep different power tools and other equipment of the same brand (pressure cleaners, flashlights, etc.) could use the same power supplies and chargers for them. This eliminates the need to use a different battery and “charger” for each individual device, and also makes it easier to find compatible power sources: instead of checking a list of compatible batteries, you just need to make sure that the battery you select is from a supported platform. (However, models of compatible batteries can also be specified in the specifications — see below for more details).

Batteries of the same platform mainly differ from each other in terms of capacity — and, accordingly, cost.

The operating voltage of the battery in the grinder with the appropriate power supply (see "Power supply"). The more powerful the tool, the higher the battery voltage, usually. At the same time, this parameter is usually selected in such a way as to optimally match the characteristics of a particular model; therefore, in fact, voltage data may be required only when looking for a spare or additional battery.

The capacity of the battery that is equipped with the tool with the appropriate type of power (see “Power source”).

Theoretically, the capacity directly determines how long the tool can work on one charge. However, in practice, this parameter is rather weakly related to real autonomy. Firstly, the charging time depends not only on the battery capacity, but also on the energy consumption (power) of the tool itself; secondly, the actual amount of stored energy is determined not only by the capacity in ampere hours, but also by the voltage in volts. So you can only compare tools with similar power and the same battery voltage in terms of battery capacity.

Note that some models of grinders allow replacing the “native” battery with another, including a higher capacity one; some manufacturers even produce universal batteries suitable for different types of power tools under a given brand.

The model of a regular battery allows you to find out in more detail its characteristics, and also helps you understand what devices it is like and which one should be purchased in case of a replacement due to a malfunction or, if necessary, buy another similar one.

Battery models that the device of the corresponding type is compatible with (see "Power source"). This information will be useful in cases where the battery(ies) must be purchased separately, for example, if the tool does not come with a battery at all, if you need to supplement the original package, or if the existing battery has failed.

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.

Approximate noise level generated by the grinder during operation. Note that this indicator is quite approximate, because. actual "loudness" can vary markedly depending on the type and shape of the material being processed, the surface it is placed on, and other circumstances. In addition, different manufacturers may use different measurement methods. Nevertheless, this indicator makes it possible to assess how comfortable this or that model is in operation and whether special hearing protection is required.

The most “quiet” modern grinders give out about 65 dB — this is comparable to loud speech at a distance of 1 m; in the loudest, the noise level reaches 107 dB — this is the volume of an industrial workshop.
