When purchasing a screwdriver, the purchase of various attachments to it remains unchanged - a bit. There are a huge number of manufacturers of these consumables on the market. My choice fell on the Taiwanese manufacturer Whirlpower Taiwan PH Philips. These bits have a hexagon on the reverse side, the size of which is 6.3 mm. The slot forged with small notches, due to which the self-tapping screw is better held, for all the time I have never had a bit pop out of the self-tapping screw during operation. Bits are magnetized, they last for a long time, about once every 300 twists. Their length is different, starting from 25 mm and ending with 250 mm.
For me, from democratic options, these bits are probably the best, of course there are better ones, for example, Magna and Vikh, but there is much more cost. So, from myself I can safely recommend them as an affordable option, with normal quality.
Minuses
There are better options, but more expensive.
