GYROS Keyless Mini Adapter Chuck, ⅛ - 3/16 Inch Straight Shank w/3 Collets, Small Drill Bit Adapter Chuck sized 0 to 0.098 Inch for Micro Drill Bits #61-#80, Micro Drill Chuck for Dremel & Power Tools

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.

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!

Why did you pick this product vs others?:As others have stated, the small chuck does not grip the small drill bits very firmly and so they often slip/let go even drilling into old growth doug fir. Otherwise this is still pretty useful as small drill bits will slip even on the regular chuck of the driver tools. I like just leaving the drill bit in place in the small chuck and removing the entire chuck when switching between driver bits or when work is done.

Bought two, love them. My drill will not clamp down on very small drill bits. But using this tool I can use very small number drill bits instead of using pin vise. Arrived on time undamaged. Great price great product recommend seller

On first use I put the chuck in my Dremel tool and as soon as it spun up the out of balance caused the shaft to bend even more. Very dissatisfied with this item. UPDATE... The customer service people at GYROS contacted me and offered a refund or replacement. I requested a replacement and it seems to be just fine. The original did not fit properly in the packaging. The replacement fit perfectly.

I can't accuse the listing of being a line. At least there was an attempt. It is technically a collet. The shaft is roughly one quarter of an inch, and the collet does adjust. I didn't bother to measure, but I suspect it's close enough to the advertised dimensions.However the shaft was on arrival. Bent enough to be seen by the mark 1 eyeball. I measured how much walk was in the bit and is was something near 250+ thousands. That is completely unacceptable for a tool that is supposed to hold a .5mm bit.The threads for the collet are very rough. It wasn't deburred at all.If you want to play a joke on a machinist, feel free to purchase one as a stocking stuffer.

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.

This is such a handy item to have. Works great - if you get a good one! Despite the packaging claims of improved quality, I've had two of these that were junk. Similar to issues with cheap dremel collets, the slots in the Gyros were cut so poorly - off center and with burs all over. I bought one locally and then one here on Amazon and both were so far from acceptable that they had to be returned. A replacement from Amazon was fairly decent so I kept it. Still not cut quite exactly the but the runout is tolerable enough to make it worth keeping (some runout with such tiny bits is pretty normal even with the good bits). So inspect yours and chuck it up for a test upon arrival and be prepared to do a return. These are made in India.
