Readytosky RC Hex Bit 1.5 2.0 2.5 3.0mm Hex Head Allen Wrench Drill Bit Set for Screwdrivers Electric Screwgun/Power Drill

These bits are better than the comments would let on. These have lasted me a few years with over 15 drones and half a dozen 1/10 scale and 1/16 scale rc vehicles they have seen plenty of abuse. If you know how to use tools, these shouldn’t break or chip the ends off. They fit excellent even after years of use. And I have used them everyday just about for years. Ordering a new set as mine are a bit corroded and before I set them in some rust remover, I need to make sure I have a spare set in case I screw up the rust remover and eat them up. In any case, people complain about the MIP brand ($40) and the traxxas brand ($30). These will do just fine if you use them correctly. Keep the 90degree right angle on them when you use them and they won’t break. If you make sure the bit is fully engaged with the screws before you dump the torque from an electric driver into them they will survive just fine. I had to search my history to find this purchase as it was from so long ago. But as an automotive technician and gunsmith, I have learned over the years to treat my tools like I treat my money. Responsible and correct. These bits have built and re-built 30+ different rc vehicles including no prep drag cars, off road truggys, mini bashers and short course trucks. Don’t abuse them and they will last you years.

Work great in my cordless screw gun

After a few cheap purchases I gave this one a tried. 1,000s of screws later and they are still perfectly shaped!! Little bent now but they were perfect when bought. I use them for my RC cars so there is not a lot of torque going to them. But these are perfect and exactly what I needed!

Work very well for the price point.

I bought these because the last set I bought on Amazon was of poor quality and the tips rounded off after about 2/3 hours. These have nicely cut tips that fit very well in hex screw head. Very little if any slop. The first one I used was 2.5mm. The shaft was not straight at all, only one out of the other three was acceptable, but not perfect. I don’t know if I got a bad set or if the production quality control is lacking. Get what you pay for I guess.
