Comparison Makita ST113DWAJ vs Makita DST221Z

A device that protects the tool from being triggered at the wrong time.

Most often in a modern tool there are manual fuses in the form of a button or switch. Such a device blocks the release button or opens the power circuit; thus, when the fuse is on, the tool will not work, no matter what the user does. This reduces the chance of fasteners "shooting" in the wrong direction and reduces the risk of personal injury and property damage.

The number of fasteners that fit in the stapler magazine.

Note that manufacturers tend to indicate the maximum number of parts in the characteristics — that is, the capacity for the thinnest fasteners allowed by the design of the tool. Accordingly, fewer larger parts will fit in the store; this must be taken into account when choosing. Nevertheless, this parameter makes it possible to evaluate the instrument and compare models similar in class to each other.

Large capacity, on the one hand, allows you to work longer without interruptions to recharge the stapler. On the other hand, volume magazines are usually very bulky and can weigh a lot on their own, not to mention the weight of the fasteners loaded in them. Also, if parts are charged one at a time, recharging can become quite a long and tedious affair. Therefore, it makes sense to specifically look for a tool for 100 parts or more(especially when it comes to thick fasteners) only if the ability to work for a long time without reloading is more important than the disadvantages described above.

The smallest length of staples (see Fastener Type) that the stapler can work with.

The length in this case means the length of the leg — in other words, the depth to which the staple clogged "to the stop" penetrates into the material. Small staples do not require much power to drive, but the tool may not be designed for fasteners that are too short due to other parameters — for example, the design of the magazine. Therefore, for many models, this limitation is quite relevant, and in powerful professional models, the minimum length can be quite large — more than 20 mm.

The largest length of staples (see Fastener Type) that the stapler can work with.

The length in this case means the length of the leg — in other words, the depth to which the staple clogged "to the stop" penetrates into the material. This means that working with staples of great length requires not only the appropriate design of the magazine and the feed mechanism — the stapler must also be quite powerful in order to provide the effort necessary for effective clogging. And this, in turn, affects the dimensions, weight and price of the tool. In fact, this means that it does not always make sense to specifically look for a model that can work with long staples — you need to evaluate the specifics of the intended work: often the best choice is a relatively “short”, but at the same time inexpensive and compact tool.

In general, a limit of 10 – 15 mm is typical for entry-level staplers, and in professional models this parameter can exceed 50 mm.

— Adjustment of impact force / depth. The ability to adjust the force of impact or the depth of clogging fasteners. These functions are implemented somewhat differently: the impact force is changed by adjusting the power supplied to the striker upon impact, and the driving depth can be set due to a mechanical limiter — for example, by retracting the striker a certain distance back, so that it simply does not was able to move beyond a certain distance. However, the purpose and use of these functions is similar: first of all, they allow you to change the depth to which the fastener is driven into the material. In addition, adjusting the force of impact (namely force) can be useful when working with delicate materials, where too powerful impacts are undesirable. Specific details of the implementation of this function should be clarified in each case separately.

— Double hit. Possibility of operation of the stapler in the double impact mode. Here, this term means the ability to drive two fasteners at once in one blow — for example, for connections that require increased reliability. Note that double impact most often only works on staples, even if the tool is able to work with other types of fasteners (see above). Firstly, it is for brackets that this possibility is most relevant; secondly, it is much more difficult to implement it for nails or pins.

— Bending the staple.... The ability of the stapler to work not only for driving staples, but also for bending their legs after installation. The need for bending arises in cases where the tool is used to fasten relatively thin layers of material, and the staples pierce the parts to be fastened through: bent legs provide a secure hold, and are also safer — the risk of scratching or pricking the protruding edge of the staple is minimal. Note that such work requires an anvil of hard material placed under the fastened materials; in some tools with a bending function, the anvil is part of the design, but most often it is not.

— Blade of knife. The presence of a knife blade in the design of the stapler. This feature allows you to use the tool not only for driving fasteners, but also for cutting material — for example, preparing upholstery for furniture. The blades are usually made removable (so that a dull one can be quickly replaced with a fresh one or sharpened with convenience) and have a beveled shape (this allows you to cut with the very tip of the knife, providing high accuracy and accuracy). However, this function is quite specific, therefore it is rare, and mainly among percussion models (see "Type") — only they turn out to be quite light, compact and convenient for use as knives.

— Backlight. The presence in the stapler of its own built-in flashlight, usually directed in such a way as to highlight the place of impact. This feature is extremely useful when working in low light conditions. Note that such conditions can easily arise even under normal ambient lighting: for example, the tool itself often obscures the impact site, worsening visibility and complicating accurate aiming.

— Brushless motor. Such motors do not have the classic carbon brushes found in conventional power tools, whose friction during engine operation leads to additional heating, which leads to unnecessary energy consumption and general engine wear. Refusal to use them allows you to extend the battery life of the tool, on the one hand, as well as the life of the engine, on the other.

Features of the tool configuration regarding the battery.

Modern cordless staplers can be supplied with or without a battery; Moreover, in the first case, a different number of batteries, or even a built-in power source, may be provided. It is also worth noting that models with a removable battery usually do not use any original batteries, but universal solutions for power tools from the same manufacturer. The advantage of this design is obvious: first of all, it facilitates the search for power sources, including in addition to or as a replacement for “original” batteries. Here is a more detailed description of specific configuration options:

- 1 PC. Staplers that come with just one replaceable battery. This package may seem almost ideal: the tool can be used immediately after purchase, and when purchasing you do not have to overpay for a second power source. However, tools with 1 battery included are rare - noticeably less common than models with 2 batteries or no battery at all. At first glance this looks strange, but in fact there is nothing unusual here. So, if there is no battery, finding it is usually not a problem; and if the device needs to be used right away, “out of the box” - in many cases, a configuration with two batteries is a better choice: it is more expensive, but has a number of noticeable advantages. Returning to models with 1 power source, we can say this: this con...figuration is designed mainly for two situations. The first is when the tool is planned to be used for short-term work, when it is possible to take significant breaks to charge the battery; the second - if the household already has at least one spare battery, so there is no point in buying a model with 2 batteries.

- 2 pcs. The most popular configuration option among tools that generally come with at least some kind of battery. The presence of a second battery inevitably affects the cost, but in many cases this point is more than offset by the additional ease of use. Firstly, two batteries allow you to work longer without interruptions - in fact, autonomy is doubled. Secondly, while one battery is in use, the second one can be kept on charge; This allows you to minimize charging breaks, or even get rid of them altogether. Thirdly, the breakdown or loss of one power source does not interfere with work - it is enough to install a second one. And fourthly, a spare battery can be useful for another compatible power tool - for example, a screwdriver or jigsaw; this is especially useful given that staplers are rarely used “alone” without other tools nearby.

- Without battery. The most popular option in principle for completing battery-powered staplers. Along with the obvious inconvenience - the tool cannot be used out of the box - this package has a number of significant advantages. First of all, the customer can choose the model and number of batteries at his own discretion, without relying on the manufacturer in this matter. And if there is another battery-powered tool on the farm, then the power source from it may well be suitable for a stapler; This will completely eliminate the need to spend additional money and time. The second point is especially relevant in light of the fact that construction staplers are often purchased in addition to an already existing set of power tools, sometimes quite extensive.

- Built-in. A rather rare option, found mainly in relatively simple and low-power models. The built-in power supply allows you to make such a tool as compact as possible. In addition, the customer does not need to bother with a separate charger - just connect the included cable to charge. On the other hand, a dead battery cannot be quickly replaced with a fresh one - the only option is charging, which requires an energy source and can take a lot of time. Also, this design does not allow you to select batteries at your discretion; and if there are problems with the power source, you will either have to take the stapler for repairs or replace it with a new one. In light of all this, models with a built-in battery are usually intended mainly for minor home repairs and simple tasks that do not involve long-term work and high loads.

The name of the battery platform supported by the device. A single battery platform is used to combine various power tools of the same brand (screwdriver, grinder, circular saw, etc.) into one line. Devices on the same platform use interchangeable batteries and chargers. Thanks to this, for example, there is no need to select a battery for each individual model of a power tool, because one purchased as a spare battery can be used in various power tools, depending on the situation or as needed. Batteries of the same platform basically differ from each other except perhaps in capacity.

The operating voltage of the battery installed in the tool of the corresponding type (see above).

The higher the power of the stapler, the higher the voltage may be required (but not necessarily required) to power it efficiently. In other words, a high battery voltage is usually indicative of advanced performance, while a low battery voltage is not always a sign of an entry-level tool. From a practical point of view, this parameter may be useful only for some specific tasks — for example, searching for an external charger for a battery or buying a spare battery. In addition, this parameter must be taken into account when comparing different batteries in terms of capacity (for more details, see "Battery Capacity") .

Modern staplers most often use 12 V and 18 V batteries.

The capacity of the battery supplied with the tool.

Theoretically, the higher the capacity, the more energy the battery accumulates and the longer the tool can work on a single charge. In fact, however, two points must be taken into account. Firstly, only batteries with the same voltage can be directly compared in terms of capacity in ampere-hours (if there is a difference in voltage, you need to convert the capacity to watt-hours using a special formula, and use these values already). Secondly, the actual battery life will depend not only on the characteristics of the battery, but also on the power consumption of the stapler itself; at the same time, the power consumption for battery models is not directly indicated in the specifications, and energy consumption has to be approximately estimated by other parameters — primarily performance, as well as the type and size of fasteners. Thus, the difference in battery capacity will only correspond to the difference in battery life if the compared tools have similar performance characteristics.
