KAIFNT K301-009 3/8-inch Drive to 1/4-inch Hex Bit Holder Socket, 3/8"DR to 1/4"H Magnetic Adapter

I have several such adapters with different features, but this one has it all. The magnet, the ring retainer, and the most important to me - the undercut dimples inside the 3/8 female part to hold the quick ratchet ball. It's made in Taiwan, so the S2 steel is great and is very compact. I don't think even the expensive Snap-Off has these features. Good job KAIFNT!! - Highly recommend this socket.

They seem well made and fit well with my current drive extensions. Very useful adapters.

I found this tool to be pretty handy for using with Torx bits. Seems to provide a good hold no noticeable slack or bit wobble. I'd recommend the tool.

Beautiful product, not much else I can add, it holdsbits well, snug and it's magnetic. I've already usedit for a very difficult to get at set of bolts, this madeit very easy.Would buy again.

This is the perfect tool for your ratchet. I use it with my cordless electric ratchet and it makes screwing and unscrewing in tight spaces a breeze. Socket is high quality Cr-V, coupled with a VERY strong magnet. The hex bits will not come our unless you want them too. Thought about making my own, not worth it once you see the value for the money here. Only weird thing is that it's marked 3/8 on the side instead of 1/4, but you learn to live with it.
