Comparison Master Tool 78-0349 vs Brigadir 57-027

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.

Dimensions of the wrenches supplied in the set. Specified as a range — from the minimum to the maximum size. In this case, the specific distribution of different types of keys over the range may be different. An example is the following set: 17 open-end wrenches, 5 box wrenches, size range 6 – 24 mm. In such a set, box wrenches are almost guaranteed not to cover the entire range of sizes, but for open-end wrenches, this is quite likely. Such details can be specified separately.

Also note that a wrench size of 24mm or more is considered quite large for today's general purpose tools. However, on the market you can find sets that include wrenches for 27 mm, 30 mm and even 32 mm.

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

Number of precision screwdrivers ("telephone screwdrivers") supplied with the tool kit. Note that some of these kits are specialized kits that include only screwdrivers for phones.

The colloquial name of such tools is due to the fact that they are widely used in the repair of mobile phones and other portable equipment (MP3 players, cameras, etc.). Some time ago, the name “watch screwdrivers” was also widely used — for similar reasons. And the term “precision” means that such devices are highly accurate and well suited for fine work with small details, where accuracy is much more important than high effort. Thus, "phone screwdrivers" have a specific design that distinguishes them noticeably from ordinary screwdrivers. So, the general shape of the tool remotely resembles a nail: the handle is made slightly thicker than the working part, and a characteristic cap is provided in the upper part of the handle. This hat is made to rotate, it is convenient to hold the tool with the other hand if you need maximum accuracy and stability.

As for the quantity, in general, the more precision screwdrivers in the kit, the wider the possibilities for using such a tool. At the same time, note that sets with a similar number of such screwdrivers may differ in their specific assortment — that is, in the types of slots for which they are designed, and in the size of the working part. These details should be clarified separately.

Number of classic screwdrivers supplied in the kit. Note that some modern tool kits include only screwdrivers, without any other fixtures or accessories.

Despite the proliferation of screwdriver handles with interchangeable bits (see above), traditional non-separable screwdrivers also remain popular nowadays. One of their advantages over collapsible counterparts is the convenience of working with different types of fasteners at the same time: keeping several separate screwdrivers with different sizes and types of tips on hand (for example, two flat and two cross-shaped ones) and taking a tool as needed is much more convenient than constantly changing bits on the screwdriver handle. Other advantages include strength, reliability, as well as matching the size of the handle to the size of the tip and the expected features of the work. So, screwdrivers for large fasteners are equipped with thick handles that allow you to develop a lot of effort; and with small tips, handles of small thickness are used, contributing to precision and accuracy.

As for the quantity, it is worth considering here: a larger number of screwdrivers gives more opportunities, however, the specific set of such tools (and opportunities) in different kits may be different. These details will not hurt to clarify before buying. Also note that it hardly makes sense to look for numerous screwdrivers for simple work — in suc...h cases, a handle with bits may be more convenient.

Additional items included with the toolbox but not listed above. Here are some of those items:

— Adapter. Adapter from one type of mount to another. Quite often, adapters are designed to fit magnetic bits (see above) with a hex shank into a tool that uses a landing square, but there may be other options — for example, adapters between different sizes of the mentioned squares (see above).

— Holder for bits. A specific type of adapter designed to mount bits with a conventional hex shank in screwdrivers where a shank with a notch for a retainer is required. In extreme cases, they can also be used as improvised screwdrivers. Several holders can be supplied, in such cases they usually differ in length.

— Level. A tool for assessing the position of a particular surface. The simplest levels are for testing whether a surface is horizontal or not; however, tool kits usually include more advanced fixtures that allow you to also control verticality, and in some cases also check compliance with a 45 ° tilt and even measure a specific angle of deviation from the horizontal / vertical.

— Depth limiters. They are used together with drills (see above). They allow you to set the maximum drilling depth — the tool simply will not go further; this is useful in cases where you need to make holes of a given depth.

— Telescopic magnetic probe. A device in the form of an extendable rod (like an antenna or a pointer) with a strong permanent magnet at...the end. Facilitates the collection of small metal parts — for example, crumbled bolts or bits — including and in hard-to-reach places (like the space under the cabinet or a narrow gap between the boards).

— Lamp. Classic flashlight for lighting in dark places.

— Tester. He's an indicator. A specialized screwdriver for searching for a phase in electrical networks during electrical work. The indicator rod is almost completely covered with insulation, and a light bulb is located in the transparent handle. Such a device can also be used as a classic screwdriver, but it is not designed for applying great efforts — the main purpose is to search for the phase.

— Fastening devices — for example, screws with dowels. In normal cases, it is more convenient to buy fasteners separately, for specific needs; however, there are situations when the "emergency stock" provided in the kit is very handy.

This list is not exhaustive — manufacturers may provide other equipment, sometimes very specific.

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.
