Review on 🔧 30 Piece Boxer Precision Screwdriver Bit Set, 4mm – Ideal for Cellphones, Laptops, Clocks, and Glasses by Jonathan Fernandez

The kit is exactly as advertised and is well made, functional and well organised. Screwdrivers are as described in the listing: different types of screwdrivers, torx bits and hex bits of different sizes. Screwdriver bits include flat standard Phillips and posi-drive Phillips (Phillips head with small wings between crossed head flanges, optional); A standard Phillips screwdriver can be used with posi-drive screws, but not vice versa, so you'll need to look carefully to make sure you have the correct bit. The exact dimensions are given; In fact, they range from "jeweler" size to the small end of the normal range. The size is engraved on each bit shank, although the markings are tiny. (Note: Torx sizes T6 and T8 and small Phillips fit case screws on Macs; I've used this set for this purpose and it works great.) The bits appear to be very good - machined; The heads are accurately carved and well finished. I can't say anything about the hardness behavior, but they seem to be good. All bits are magnetized and hold small screws very well when inserting or removing from threaded holes. The screwdriver is slightly larger than is usual in "jewelry screwdriver" sets, but is handy and easy to use. Steel shank with standard hex bit holder; Part of the handle is plastic covered and has a rubberized gripping surface, and the rotating lid is also plastic. I was a bit suspicious of the plastic handle at first, but it seems to work well. Bits and screwdrivers are organized and easily accessible in the corner slots in a sturdy snap-on case; Case and lid are made of hard plastic, but not too thin. In short this is a good set that is functional and appears to be well made; this is a great deal for the price.
