Gyros Keyless Mini Adapter Chuck, ¼ Inch Hex Shank, Small Drill Bit Adapter Chuck, 0 to 0.039 Inch, Micro Drill Chuck for Cordless Screwdrivers, Dremel, & Power Tools

It is well made.

Love this little screw bit to chuck adapter. Works incredibly well. Fits perfectly, easy to use, and the teeth line up well with the drill bits. Can only be used with smaller bits, but it's great and lightweight, and precise for those smaller jobs, without adding a bunch of extra heft to whatever tool you're using, like an electric screwdriver. All in all, should get some good use out of this!

I received a bad batch of amplifiers and had to replace them. They were 15 pin thru hole parts. The task of removing the ICs from the board and then cleaning out the solder from the plated thru holes in preparation for the new parts was very time consuming. The worst part was adequately clearing all of the solder from the holes. I decided to try and clear the holes with a drill bit. I found #64 drill bits an this site. The Gyros Keyless Mini Adapter Chuck was perfect for this task. I was able to securely fix the drill bits in the chuck and the 1/4" Hex Shank fit perfectly in my cordless screwdriver. I am now able to replace the ICs 4 times faster.

Very true

I bought the 1/4" drill chuck and when it arrived I put a #60 wire drill bit in it, for jewelry work. The chuck centered well and fits into the larger drill chuck just fine. Craftsmanship seems very good, and it performed well. This chuck is designed to be tightened with fingers, although you can use small pliers if your need to really torque down on your bit to keep it from spinning in the chuck. I had no trouble with finger tightness. There were no troubles or rough bits with this chuck, it is just as in the pics for the listing.
