Total number of items

The total number of items in the set. In this case, both the actual bits and end heads are taken into account, as well as additional accessories such as an adapter, a bit holder, etc.

The more items in the set, the wider its possibilities. However, note that the specific composition of the kit may be different, so when buying it is worth specifying not only the number of items, but also their specific types.

SL bits (Slot)

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

Marking SL means bits with the simplest flat tip. For such a tip, in principle, strict compliance with the size of the slot in the fastener is not necessary — it can be a little narrower or a little wider. In addition, flat-slot fasteners are used relatively rarely today, more advanced varieties have become more common. Therefore, the SL-type bit in the kit, usually, is not much.

SL bits sizes

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.

PH cross bits (Phillips)

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).

PH bits sizes

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.

PZ cross bits (Pozidriv)

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

The PZ is a modified version of the PH cross tip (see the relevant paragraph). In PZ tips, the angles are more pronounced, there are additional edges to increase the contact area with the slot — thanks to this, unlike PH, these tips do not push out of the slot even with a very large effort. All this makes the PZ a fairly convenient option for working at high loads, including uneven — in particular, for tightening self-tapping screws.

PZ bits sizes

The sizes of the PZ 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 "PZ1, PZ2x2" means one relatively small bit and two larger ones.

T bits (Torx)

The total number of Torx bits supplied in the set.

The Torx tip has the shape of a six-pointed star. This provides a larger area of contact with the fastener than flat and cross bits, and allows you to work with higher forces.

T bits sizes

Sizes of the Torx 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. The specific size to which this or that number corresponds can be clarified according to special tables. If there is more than one bit, the number of bits is specified after the size. For example, the entry "T7, T8x2" means one bit of T7 and two of T8.
