HobbyfireTitanium 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

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. :-)

I saw a lot of reviews saying the go to speed bits are mip brand speed bits. But I didn’t want to spend 35-40 bucks for just 3 bits. So I decided to buy these since they caught my eye and had good reviews. When I got them I was impressed by the quality and feel of them. They have a good weight to them and nice finish. Then I removed various screws on my Arrma big rock to check the fitment. It was perfect on all sizes. No wobble and it was a snug fit. I’d say if you are looking for a good quality set of speed bits without wanting to spend the money for the mip bits, try these out.

They are better than the Traxxas bits and way cheaper

I got these to use with my electric screwdriver for working on my RC cars. They are very hard and don’t dull easily. I’ve found that they will damage some screws if not perfectly straight on. They work best with good quality hardware. If the screws are soft. I’ll use my manual tools to prevent stripping them out.

Thank you for the lenght. They fit into clean 2mms tight. shaft inside driver started to spin on them after a few months of use. 5000+ screws.
