Extra Long Security Bit Set 32-Piece, 6” Long Shank Tamper Proof Torx Bit Set, CRV Steel Drill Bit Set with Holder

These bits are very good and do not chip. Got these because I needed longer bits at work and these have absolutely been phenomenal using on my job. The bits do not ship on the tip so far and work very well

Perfect for cheap!

The bit sizes (working end) seem to be the correct size, but the body is just a little large.It will fit in a 1/4" socket, but not fit into my 1/4" drive impacts.

There are times when you just need an extra long driver bit for those hard to reach areas and this does a great job of providing a comprehensive set with probably a few sizes that you'll never use. Nonetheless, for the price and quality, this has worked out great for me in situations where a deep hole is too small to use a regular 1/4" extension adapter with a regular bit or the hardware is just in a tight spot. These driver bits will fit any standard 1/4" hex socket drive or drill chuck. They come neatly arranged in a rubberized holder which is basic but does the job. There's even a gap in the middle to store extra bits if you have them.The only negatives I've observed so far with these is that the stamped labeling can be hard to read on some of the bits due to them being faint. Not on all but for some you may need a magnifier or angle it to the light to get a clearer visual of the label. It would have been great if the set included some square drive bits too but I'll still give it 5 stars for the price and having this handy set of extended drivers that will work on standard and tamper-resistant hardware.

The very first bit was a pain to get INTO my impact drill. Now I know these are not meant for impact drivers, so any damage from these uses are not being noted. I've never had any bits not fit into my drill. These have burrs on them that you can't readily see, but definitely notice.Anyway, even with my regular drill driver, these are weak/soft metal bits and it doesn't appear as though they'll last through many uses. I would recommend saving these for ONLY when you need that extra length.I put these into an outdoor storage container overnight while we were working on a project. The next day half of these had rusted significantly. There must have been SOME moisture in that box. However, I didn't note rust on any other items I had put in there. Like my smaller chop saw, assorted screwdrivers, measuring tape, other driver bits, and my drill bits.I was not too impressed by these. They're not easy to take out of the holder, especially if you have thicker fingers. You may be better off storing them in a plastic box. I do love the length, which was the primary motivator for the purchase.At 50 cents a piece, these aren't a terrible deal. If I knew what I knew now, I might keep looking for another set. I'm on the fence though...hence the 3 stars.

I use these bits in the electrical engineering environment for building of PCB test boards for production tests. The test boards I build are big (close to 1 meter long in some cases and weighs approximately 30 lbs). The boards are big and thick (32 layers is typical) but still need a stiffner ring around the board for support. The combination of Philips and security bits makes it a perfect set of bits for the environment I use it in. The spanner bits works great for installing SMP blind mate RF connectors. The torx bits are great because part of the hardware and designed in Germany and they sure love those torx. I use these bits with the Dewalt 8V gyroscopic screwdriver to make sure all the connectors and screws are not over torqued.These bits are definitely not designed to last in the construction environment. It will work, but you will end of shearing off the tips really fast, especially if you use it with an impact driver. However, if you are using it in a controlled environment like at home or a hardware lab, these bits should last long.

I liked the idea that I had extra reach at hand but was quickly disappointed with the first screw I installed with my No.2 Phillips tip. I was securing a valance cleat and the tip broke in half. Maybe these weren’t meant for construction use but more geared around product assembly.

I have a jump starter with a depleted battery after so many years. I attempted to open it and change the battery inside but failed to do so, as there are screws located in two locations that I can't reach with the screwdrivers I have in my toolset.Then I saw this set. Amazing! It has all bits I have seen on some devices and bits I have never seen before.These are long bits (15cm 6") which have a standard hexagon base to fit in to regular screwdrivers that you can install different bits.Material is just great and strong. The silicon holder is really useful and keep all bits in place.Yes, I managed to open my jump starter and replaced the battery inside, it works like new and saved me a lot of money.Highly recommended to have in the toolbox if you are handy. You will possibly not use them often but one use will recover the whole cost of the set.
