Hymnorq Keyless Mini 3-Jaw Drill Chuck Screwdriver Adapter with Quick-change 1/4" Hex Shank to Hold Stright-shank 0.3-6.5mm Drill Bits Milling Cutters for Micro-production or Medical Industry

Smaller than my needs but the item works just fine.

We've all broken one or more of the small drill bits we need for starter holes. And many of us have wrapped a tiny drill bit in tape in an effort to get it to seat in a standard drill chuck. That latter solution is usually unsuccessful, producing an out- of-round effect as the bit wobbles as it turns. After breaking three small bits in a standard chuck and failing to find a way to get my one remaining tiny drill bit to seat, I ordered this chuck. When it arrived, I put it to work immediately. It is easy to hand tighten, holds the bit perfectly (no wobble) and looks like it is very solidly made. Further, it provides greater control and is easier to use with small bits because it projects an inch or so in front of the standard chuck and is of narrower diameter. I cannot believe I waited all these years to get one of these! Smart purchase and I look forward to a future of more successful starter holes.

This chuck is virtually impossible to get to run true in a drill press. Yes it will hold a small drill but to drill accurately is out of the question. I would not recommend.Update: The vendor promptly responded to this review and offered a refund as well as UPDATED the product description to reflect that this micro chuck is not suitable for use in a drill press. I will raise the stars to four because of the excellent customer service of this vendor.I’m very happy with the fit and finish of this chuck it just didn’t work for my intended purpose.The reason the micro-chuck is not suitable is most all drill press chucks have 3 jaws (120 degrees). The area of the micro-chuck that these 3 jaws are suppose to grab is six sided (60 degrees) so you can never get a symmetrical hold on it to get it to run true.It would be great if the mfg offered a version of this micro-chuck that would work in a three jaw chuck!

I got this mini chuck because my son was building a project for school out of balsa wood and I felt that my Dewalt drill was too big for him to handle safely and precisely. This chuck fits right in my small electric screwdriver which he can hold easily. The RPMs on the driver are low enough to not rip the wood out of his hand.Something that did not occur to me when ordering is that I can now use this chuck in my big Dewalt drill to hold drill bits too small to fit into the big 1/2" chuck.I did not have any issues with the chuck gripping the drill bit incorrectly, but I guess I can see that is a possibility. If you are careful while tightening the chuck, you should not have any problems.

The irony of this crap is that you can only use this chuck on a drill with a chuck!! It’s the only place it will stay and not fall out while one is concentrating trying to work. The hex chuck at the bottom where it’s supposed to catch on the impact driver is too long. I mean, one would think that the manufacturers are professionals and would know their stuff, but nah! Another group of individuals chasing an easy buck, basically successful at catching bees with with crap on a stick.The problem with their positive reviews and rating is that they are selling multiple items under the same banner, so they get away with selling garbage as treasure and Amazon doesn’t do anything about it.

Seem like a decently made little unit for the price so far. Runs pretty true, (was kinda' skeptical for the price LOL), and did exactly what I bought it for; held .030 drill and drilled through the tiny little arm of my glasses so I could repair them with a pin. Recommend

Recently bought a Black & Decker rechargeable screw driver, and it did not come with a "jig" that holds mini drill shafts so to drill a pre hole to screw something in. This "Migiwata" fits the bill perfectly.The end of it fits right in where the screw driver bits fit. Didn't need a super fast drill just a screwdriver speed drill.

Yes, it holds the tiny drill bits I need but they wobble.I put the smallest bit (3/32") my drill press can hold and got dead smooth drilling. I put every bit the Mini 3-Jaw Drill Chuck could hold and every one 'wobbled'. I do delicate fretwork on my scroll saw and need tiny starting holes. This product turns a 1/16" hole into a 3/32" hole. That is too big for some of my work.
