Titanium 1/4" Drive RC Hex Driver Bit Set 1.27mm 1.5mm 2.0mm 2.5mm 3.0mm Allen Wrench Keys Compatible with Electric Drills Impact Drill (5-Pack)

Top quality

Not sure what material they made off. But 1.5mm snapped clean off after less then 5 uses

I'd recommend to buy this over MIPs set because of the price and you get more sizes. I also have Moore Ideal Products (MIP) 9512 Metric Speed Tip Set and Neiko Hex Allen Power Bit set (do not buy Neiko they do not fit and strip hexs where the mip bits do not). These fit just as good as MIP. I had a hex screw where the hex part was worn down and so nothing could bite down and kept spinning (not the fault of the tools, but bashing with my Kraton). There were shavings left on the bit head, but no damage to the hex tip. Next, I used a bigger size and hammered it in the hole, this allowed for the screw to become loose, again no damage.

I first tried a cheap China special from Ali express but brand new size was off and got refunded so went back to old reliable amazon and wow are these nice! Perfect fit, so well machined. They don’t feel like they will break or strip easy either. I highly recommend these hex drivers if your in the market. :-)

Great tough little hex pieces

Good quality

Long bits make it easy to get into places, and they seem durable!
