Comparison Graphite 56H604 vs Bosch 2607017322

The sizes of the SL type bits included in the set and the number of bits of each size.

For the bits themselves, see above. The size is indicated by a number indicating the width in millimetres; if the bit is more than one, after the size their number is specified. For example, the marking "SL4, SL6x2" means one bit for 4 mm and two for 6 mm.

The total number of bits of type PH supplied in the set.

The PH marking stands for a classic cross-shaped tip without additional tricks. These bits have a larger area of contact with fasteners than flat SL bits and allow you to work at higher torques. At the same time, when the load increases to a certain level, such a tip pops out of the slot. In some situations, this is an advantage, because avoids damage to the tip and fasteners due to too much force; however, other types of tips, such as PZ, are better for working at maximum forces (see the relevant paragraph).

The sizes of the PH type bits included in the set and the number of bits of each size.

For the bits themselves, see above. The size in this case is indicated by a conditional number; the larger the number, the larger the slot for which the nozzle is designed. If there is more than one bit, the number of bits is specified after the size. For example, the entry "PH1, PH2x2" means one relatively small bit and two larger ones. And there are also very small sizes PH0, PH00 and even PH000. Such bits, due to their tiny size, are appropriate for repairing phones, watches, cameras and other small electronics.

The number of bit holders supplied in the set.

In most cases, a bit holder is a kind of "extension" for bits of standard length, designed to be installed in a screwdriver (extended bits can be installed without a bit holder). On one side of this "extension" there is a seat for complete bits, on the other — a standard hex shank. In some cases, such a device can even be used as an improvised screwdriver if there is no full-fledged screwdriver handle at hand.

In addition, some manufacturers call bit holders adapters from a hexagonal bit shank to a landing square of one size or another.

There is rarely more than one bit holder, however, there are exceptions to this rule when holders have different shank sizes.

The total number of sockets for 6 faces supplied in the set.

The hex profile is extremely popular in today's fasteners, sometimes even referred to as "standard". This is due to ease of manufacture, a large contact area with nozzles (which allows you to work with high forces), as well as suitability for use in hard-to-reach places (without a “ratchet wrench”, such fasteners can be rotated every 60 °, which in most cases is quite enough). As a result, if there are socket heads in the set at all, there will most likely be hexagonal nozzles among them.

A device in the form of a long rod, one end of which is inserted into the tool, and a working nozzle (usually a socket head) is attached to the other. The extension allows you to reach fasteners in hard-to-reach places where you can't reach with a regular-length tool.

Way of storing tools, standardly provided by the kit.

— Plastic case. Hard case made of plastic with nests for items included in the set; nests can be provided both in the lower half and on the lid. The case can be useful not only as a storage / transportation device, but also as an element of space organization directly at the workplace. Solid walls reliably protect the contents from both contamination and contact with foreign objects. Plastic cases are less durable than metal cases, but in most cases this difference is not critical.

— Metal case. Metal cases are in many ways similar to the plastic cases described above. This material is considered more durable than plastic, but in fact this difference is insignificant — especially considering that rather thin metal is used for tool cases. Another feature of such storage is tool nests: in metal boxes, they can be very conditional, or even absent altogether.

— Rail. The rail in this case is a clip plate, usually metal, on which nozzles are placed in a row. They are inserted into the longitudinal groove and fixed by the landing square. It is best to remove the nozzles from the rail in turn, shifting to the edge of the groove. Therefore, this method is mainly suitable for long-term storage, and not for everyday placement in the workplace.

— Cassette. This term can refer to several types of packaging. So, some cassettes look like small boxes with nests for objects and a transparent lid; ot...hers have the appearance of an oblong trough, in which nozzles are placed side by side; still others look like a cylinder with holes in the end, playing the role of nests. The common features of all cassettes are: firstly, small size (this is how cassette boxes differ from cases); secondly, the presence of clearly allocated places for each item.

— Blister packaging. Packing made of dense transparent polymer, complemented by a backing of paper or transparent material. Note that many blisters are disposable and are designed only for the delivery of the kit to the end customer; after extracting the contents, such disposable packaging becomes unusable.

— Plastic holder. Plastic bar with protrusions on which complete nozzles are put on. Holders are not as convenient for long-term storage as cases, because they do not cover the contents of the kit from contamination. On the other hand, this is a rather convenient option for the daily organization of the workplace — each item is removed from the holder independently of the others, and the holder itself is relatively small.

— Lodgement. Open tray with recesses for individual items. Note that not all lodgements are suitable for carrying without additional packaging: items in the nests may not lie very tightly and fall out when the tray is turned over. Trays are slightly better for long-term storage than plastic holders, and are also handy for organizing your workspace.

— Case. A soft case, usually, made of dense fabric and with nests for individual items. However, “soft” is a relative term: some cases have hard walls and resemble boxes. A rather specific type of packaging that is rare.

— Cardboard box. Cardboard is inexpensive, but fragile and wears out quickly. Therefore, cardboard boxes are designed rather for the role of “sales packaging”: sets are delivered and sold in them, but after unpacking, such containers are poorly suitable for further storage.
