Security Hex Inch 90mm Power Blade Set, 10 Piece

I now have nearly all they make. The 3.5" versions are great for a cordless drill (2" bits are frequently too short for me). These are smooth, clean, and have never shown signs of rusting. I do keep them in the bag when not in use, though. The tips always fit the fasteners appropriately, and I've yet to gouge out a head with one of these bits. $2 each is a little steep, but they do last. Couple these with Bondhus L or T keys and you have good hex drivers!

These fit perfectly on hardware they’re designed for. Strong with good finish.

This was an interesting product- with the shape of the mounting base I thought this was to be used in a power driver like a drill or cordless screwdriver. It could be used like that but there are two handles made for these power bits- they grip the base quite securely and the handle is very comfortable. I often work in small items and having a bit with a tip that fits properly is important to me. These bits have their Rockwell hardness specified- how often do you see that? Wiha and Knipex are two German tools who actually give that specification. This is a high quality tool, like the way it feels and the control the matching handle affords. If you enjoy good precision tools I think you will like these.

In trying to remove a hidden security Allen key I bought this SAE set. The metric set only have 4 sizes so the odds were better. I now own both and still do not have the correct size. This is not Wiha's fault. They make a quality tool set and well built.

Purchased these with stubby driver. Appear well made and expect long life. Wish each bit had been secured in ascending size in a plastic case rather than loosely contained in a plastic bag, which makes selecting the proper size a hunt and peck situation. Their smaller micro-torx bits are secured nicely this way.

Our aircraft is equipped with connectors that require the use of 3/32 and 5/64 Allen wrench. I have tried Allen wrenches, Allen T handles and various bits and nothing comes remotely close to these beauties. My only wish is that Wiha would have a longer set (though I have not had the need for it as of yet). This has set is worth its weight in gold for sure.

Needed a long, THIN 3/32 hex driver bit to use on a low-but-specific torque spec. The whole set was just a bit more than other sellers single bit offerings. Got it today, worked just fine for the torque spec needed (15 in lb in a very thin / deep recessed hole). Didn't need them for the 'security' and figure they might be a bit more easily deformed, but the low torque spec I needed it for is not an issue.

I’ve been using these things daily/weekly with a Bosch 12v impact driver for 2 years and they are probably my favorite tool in my tool chest. I’m very impressed with how they have held up. I wish these were always available but it seems that Wiha only does limited runs. If these are available buy them. You won’t be disappointed unless of course you are expecting them to be sharp.

Like it very much

Very useful bit set. Works perfectly with a power drill. Just wish there was a larger range of bits in the set.

Needed to remove deep set bolts with security torx heads. These did the job.
