Review on 30 Pcs Magnetic Screwdriver Bit Set 4 Inch, Mixiflor 1/4" Hex Shank S2 Steel Long Drill Bits With Storage Box (Slotted+Cross+Square+Torx) by James Roper

I already have many of these security bits, but they are very short. For many applications, you have to use an extender which makes it wobbly and difficult to control. and then the bit sometimes falls out. These bits solve all that. The 4" length is a nice middle-of-the-road length. The hex shaft can be used in a drill or with a hex handle.The bits are heavy-duty and well made with a nice chrome finish. There were no observable defects of any kind. There's a wide assortment of bit types, with emphasis on the security type for use on tamper-proof heads. But also a nice mix of common Phillips and flat-head, which will probably get more use. Each bit is stamped with the type and size.The case is good, but at 4" these are just short enough to fit into my Harbor Freight storage case where I keep other driver bits. So I probably won't use the case.Bottom line, for 30 four-inch bits, the price point is very attractive. Material and build quality are good.
