Screwdrivers with position change mechanism are distinguished as a separate group.
Separate attention while choosing a hand tool should be paid to its additional functions. This could be a ratchet mechanism (reverse), telescopic tip, percussion base of the handle, dielectric winding with LED, flexible shaft, tool kit in the handle.

Good afternoon dear readers. Today a little bit about the screwdriver with bit set for small jobs. Such sets are quite popular among online shopaholics and their reviews are published regularly. This set is notable for its low price and really hardened bits. on that below. Let’s start with the box: On the other side of the sticker with the composition of the kit: No mention of a brand, but the set looks like Laoa or Jakemy, I do not remember exactly. On the side there is a catch: When you open the box the bits are stacked at an angle: But once you press the “OPEN” button, the bits will almost rise to a right angle. Set contents: Set weight: The main item is an aluminum screwdriver: length 15 cm. Quality workmanship. Like this in your hand: three rubber rings for extra grip.
- torx 2-20
- hex 0.7. 6
- flat screwdriver 1,5-4
- cross 1-3,5
- triangle 2 and 3
- Three-armed star (often in BP) 0.6 to 2.5
- and also exotic U 2.6-3 and S0-S2 squares.
How did I get along without such a set? To be exact, I had a set with a couple of dozen bits for 300, but I twisted all the bits on it when disassembling the knives. Had a kit for radio-controlled models, but there is a limited number of tools.
Such set is good for working with small devices like clock: The same set is good for dismantling power supplies and blades (there are usually tricky screws).
Testing the real hardness of the bits: Bulk hardened 58 on a pair of sample bits. This is a good result. The bits have brown coating, I peeled it off with the sharpener: The alloy check is not clear: But I think it is a common carbon steel, something like Steel 45 (the instrument does not show the carbon). Although the claimed S2 is also typical carbon steel.
What can I say in the end, I kept this set for small jobs and ordered another one for my money as a gift to a friend repairman. Good quality for modest money.
