Yakamoz 11 Piece Magnetic T6-T40 Torx Head Screwdriver Bit Set - Security Tamper Proof Star 6 Point - Drill Bits - Tools with 1/4 Inch Hex Shank, 3 Inch Length Review

It worked but neither t15 nor t20 fit perfectly on the screw I need them for and the center holes are not centered. For almost 10€ I would have really expected a better quality.

I highly doubt this is AISI-SAE S2 steel as the product description states or if so the manufacturer hasn't looked into it the heat treatment taken care of. a step that actually hardens the steel. Severely deformed after only a dozen screws and with very little torque. Secure Torx is a sophisticated bit design. Don't buy this.

Bought these for some specific electronic screws they worked well with. I recently removed some rusty bolts on my truck using an impact wrench and one of these bits. I was sure the bit would break, but it actually held up great, loosening the bolts under a lot of impact pressure and not even bending the metal tips. I was very impressed with the price, range of sizes and strength of the material.

Came better than expected. I was very happy and surprised that I didn't break them. I work on European cars and have used one of these kits to break a bolt on proven rotors. I just waited for it to deform and it continued to snap out the bolts and bang from the impact. Excellent value for money and I only recommend them for an emergency back-up kit. The packaging was really nice and strong. I ended up putting them back on the holder in my car tool kit packaging and it's great.

I bought these, only needed a bit but it was cheaper than a bit from a more well known seller (e.g. Bosch, DeWalt etc). The bits appear to be fairly well made, but not particularly accurate when it comes to size. Not a bad deal if you need to use them once or twice, but if you plan on using them for some time I'd probably recommend getting a better set. You will spend more but get a better product.

I bought these to help with the many screws holding the new motorcycle plastic in place. The kit comes with pretty much everything you need but since the magnets I received weren't strong enough to hold the screw in place I sent them back. They are made of questionable materials as one of the bits has started to round off on a stronger bolt set than most bolts. Idea for everyday use.

I had a whole bunch of Xbox 360 wireless controllers that I wanted to disassemble and clean. I had a small L-shaped key for the security bits, but they are. I tossed one of these into a cordless drill and quickly disassembled, cleaned, and reassembled all of the controllers. However, do not use them for regular Torx screws; The center hole makes these bits much weaker than standard torx bits. I haven't broken anything from this set, but I have broken several torx security bits from different…

I always use my products before I write a review. I'll tell you right now. Don't even think about buying them. I use a ton of torque bits in my shop for props and whatnot. On my first use, I drove a torque screw through wood and the bit bent, twisted and fell apart. I think I was surprised, but maybe I wasn't. I threw it in the trash, I couldn't even use it for the second screw. Definitely not heavy duty, definitely not strong, definitely not high quality steel as they claim. It's difficult to…

I used it to disassemble a total of 12 hard drives lying around. I had to go inside to destroy the disks and make it impossible to recover the data. I used them with a Black and Decker cordless drill, a very underpowered Walmart model we've had for years, to speed up the process and save my hands. Wrist. Luckily I removed each drive's cover before I broke anything, but shortly thereafter I quickly broke 4 of them by removing the components from inside the hard drives. The "tool" steel they're…
