Security Hex Inch 90mm Power Blade Set, 10 Piece

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.

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!

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.

Very well made, far more durable & stronger than cheap “bargain” tool store sets! I own a number of Wiha manufacturer Ed sets & individual tools, drivers, electrical service items & very satisfied with them all; Quality that’s worth the extra investment.

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.

We purchase Wihaa products because they are manufactured in Germany and have an outstanding reputation in durability, quality and value. Going forwards we will look to other manufacturers.

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.

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.
