Comparison Bosch 2607019331 vs Bosch 2607017195

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.

Working size range of hex sockets (see above) supplied with the kit. This parameter allows you to evaluate how the heads fit the dimensions of the fasteners with which they are planned to be used.

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).

Varieties of bits (see above) included in the set.

Note that this paragraph specifies not just the size, but also the type of slot for which this or that bit is designed. This type is indicated by a letter index followed by a number describing the size — for example, SL5. Here are the most popular designations found in modern bits:

— SL. Flat bits for straight slot. The size is indicated in millimetres.
— Ph. Classic cross bits. The size is indicated by a conditional number.
— P.Z. Bits for a modified cross slot with improved engagement, have additional edges. The size is indicated by a conditional number.
— TX, T. Torx bits, with six-pointed sprocket tips. The size is indicated by a conditional number.
— H. Hex bits, with hex tips. The size is indicated in millimetres.


If there is more than one bit of a certain type in the set, the number is specified after the designation, for example, PH2x2.

An adapter for docking seemingly incompatible elements from a set. For example, socket heads with an unsuitable landing square on a ratchet, screwdriver handle or in a drill driver. The adapter provides full-fledged work with all the required list of tools from the set.

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.

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.

Adjustable wrenches are all types of wrenches in which the distance between the jaws (that is, the working size) can be changed at the request of the user. The most famous type of such a tool is open-end wrenches (see above), in which one sponge is made movable and moves using a characteristic worm mechanism; colloquially, they are sometimes referred to as plumbing. Also referred to as adjustable are the so-called gas or pipe wrenches. Their jaws are located at an angle to the handle, and the mechanism is designed in such a way that the key not only adheres to the fastener, but also compresses it. Both varieties are quite common, so before purchasing a set of tools with an adjustable wrench, it would be useful to clarify the type of this wrench.

Note that the range of adjustment of such tools is quite extensive. In one fixture, it may well cover almost all sizes of fasteners found both in everyday life and in many areas of professional use (with the exception of perhaps the smallest or largest — but other tools can be provided for them). Therefore, usually, it does not make sense to include more than one wrench in the delivery set.

The number of hex wrenches supplied in the kit. Note that some modern kits include only hex wrenches, without any other fixtures or accessories. It is also worth emphasizing that in this case we are talking about the simplest hex wrenches. Imbus tools — similar in purpose, but different in design — are highlighted in our catalog in a separate category (see below),

Keys of this type usually have the form of L-shaped handles made of a hexagonal rod. Thus, the user can work with both the short and long side of the key; in the first case, the long part of the letter "G" works as a lever, providing a good effort, in the second — it plays the role of an extension. And such tools are used for bolts and other similar parts with a hexagonal cut in the cap. Such splines have a number of advantages over the classic straight and cross splines (in particular, better tolerating high torques), which makes them quite popular — in particular, in bicycles.

As for the quantity, it is worth considering here: sets with the same number of keys of the same type may differ in the specific sizes of these tools. Such nuances should be clarified before buying separately.
