Total number of items
The total number of core items included in the set.
In this case, the main items are all devices that are directly used during work: non-separable tools (traditional wrenches, hammers, pliers ...), elements of collapsible tools (for example, a ratchet for removable heads and 5 such heads will be considered 6 units) , as well as accessories (such as extensions or universal joints). Additional accessories — such as lights — may or may not be included in this count, depending on the manufacturer; however, there are usually few such accessories, and they do not fundamentally affect the total number of items.
The most modest modern tool kits include
up to 25 units. However, such kits are very popular — they are inexpensive and at the same time can be very versatile.
25 – 50 items is still quite a small number,
50 – 75 pcs can be called an average,
76 – 100 items are more than average, and the most extensive modern sets can include
100 – 150 items or even
more.
The general rules for choosing this parameter are obvious: a more extensive set, usually, is more multifunctional, but more expensive, weighs more and takes up more space. It is also worth bearing in mind that with a similar number of items, the specific assortment of these items in differ
...ent sets may be different; so when choosing, it is worth specifying not only the number of tools, but also their specific composition.Socket heads (6 points)
Number of
hex sockets included in the tool kit.
All end heads are accessories for a collapsible tool; during operation, they are mounted on a ratchet, wrench or other similar device. The head itself has the appearance of a characteristic “cap”, which, during operation, is put on a bolt, nut, etc. This design, among other things, allows you to work with parts located in recesses and some other hard-to-reach places that cannot be reached with open-ended, captive or split keys. And compared to a set of classic socket wrenches, the holder plus socket set takes up much less space, providing almost the same functionality.
As for the 6 faces, this type of socket head is the most famous and widespread, because. most modern nuts and bolts have this shape.
Bits
The number of
bits supplied with the tool kit.
A bat in this case is called a working nozzle, which plays the role of a screwdriver tip; in fact, they are most often used with screwdriver handles (see above).
Many types of splines (slots) are used in modern fasteners — starting with the well-known
straight, cross-shaped (
Phillips and
Pozidriv),
Torx sprockets and ending with exotics like Torq-set (a cross with lines shifted from the centre), Pentalobe (with five ledges), etc. .P. In addition, the size of the slots can also vary, and in many cases, tool matching in size is very important. Accordingly, the more bits supplied with the set, the more versatile it is, the higher the probability that it will contain a nozzle of the desired type and size. However, the specific list of bits in the kit also does not hurt to clarify — in order to make sure that it has all the varieties you need. In the characteristics of individual sets, these data are given in the paragraph "Bit sizes" (see below).
Drills
The number of
drills supplied in the kit. Note that some modern kits include
only the overhead, without any other fixtures or accessories.
Modern drills can differ both in diameter and in purpose (for wood, metal, concrete, etc.), as well as in the type of shank. As with other bits, more drills mean more options, but the specific set of options can vary, so it doesn't hurt to check them out.
It is also worth noting that, unlike most of the working nozzles described above, drills are not designed for use with hand tools — except with rotaries, which are extremely rare today. Therefore, it is worth paying attention to sets equipped with such accessories only if the farm has a drill or rotary hammer (or if such a tool is planned to be purchased in the future). And many sets with numerous drills are initially created precisely as an addition to electric or pneumatic tools.
Screwdriver handle
Number of
screwdriver handles supplied with the tool kit.
Such handles, in fact, are screwdrivers without a tip — in its place there is a seat for a bit. It can be either a square (see above) or a hexagon socket, often magnetic; in fact, the presence of more than one handle in the kit is typical mainly for cases where different types of fasteners are used. Also note that, in addition to fixed mounts, in which the bit is fixed rigidly, there are also reversible devices — with a ratchet mechanism, similar in operation to ratchets (see above).
Theoretically, bits can be used with other types of tools — for example, the ratchets described above — and in many sets this possibility is directly provided. At the same time, it is work in the format of a screwdriver that is considered the classic option, and often it is he who is optimal.
Magnetic grip
Magnetic head on a conventional or telescopic extension, designed to get nuts, bolts and other metal parts from hard-to-reach places.
The magnetic grip is most in demand in auto repair shops in order to extract metal fasteners in a cramped engine compartment of a vehicle.
Weight
The total weight of the tool kit. Indicated with a case, stand or other storage/transportation device (see Tool Storage). First of all, you should pay attention to this parameter if you plan to often carry the kit over long distances — the lighter the weight, the easier it will be to do. At the same time, extensive sets inevitably turn out to be weighty.
