Rated pressure
Air pressure for which the
pneumatic nailer/stapler is designed (see "Type"). It is this pressure that the compressor to which the tool is connected should give out: if the pressure is too low, the efficiency will noticeably drop, and if it is too high, it can lead to breakage and even injury.
Air consumption
Normal air consumption during operation of the pneumatic nailer/stapler (see "Type"). Indicated per one hit; knowing the performance of the tool (see below), it is possible to assess whether the performance of the existing compressor is enough for the normal operation of the stapler. For example, for a model that produces 150 beats / min and consumes 3 liters per beat, ideally at least 3 * 150 = 450 liters of air per minute are needed. At the same time, in fact, even the most experienced operator finds it difficult to maintain a pace of 90 bpm or more; therefore, in fact, even relatively low-power compressors that do not reach the perfect value often turn out to be quite suitable for "quick-fire" staplers.
Max. staple width
The largest width of staples (see Fastener Type) that the stapler can work with.
The width of the bracket is, roughly speaking, the distance between its legs. Different situations and types of work require different sizes of staples, and sometimes the width must be quite large. However, a staple that is too large simply will not fit into the store, not to mention the fact that the stapler can “shoot” it normally. Therefore, this limit cannot be exceeded, and if you plan to work with brackets, you should pay special attention to the maximum width when choosing.
Min. staple length
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.
Min. nail length
The shortest length of nails (see Fastener Type) that the stapler can handle.
The shorter the fastener, with the same thickness, the less effort is required to drive it, but a nail that is too short simply cannot stand under impact normally. Therefore, for many instruments, this restriction is directly indicated. It is worth paying attention to it first of all if you plan to work with small short nails.
Case (bag)
The presence of a case or bag in the tool kit.
Such accessories are more convenient than impromptu packaging, they greatly simplify the storage and transportation of both the tool itself and accessories / consumables. At the same time, cases are the most popular in construction staplers — characteristic suitcases made of solid material. Such a suitcase perfectly protects the instrument not only from moisture and dirt, but also from shocks and shocks; it is also often used as the factory packaging in which the tool goes on sale. Bags made of soft material, in turn, are less common: they do not provide such protection against impacts, and they do not resist water / dust as effectively. On the other hand, such packaging itself is less bulky, and when the bag is not needed, it can be rolled up quite compactly.
