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

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.

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

It is very convenient, but the small springs that hold all three teeth in place are not very strong and when you’re drilling move out of place.

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.

It worked nicely for 30 min. Then it became garbage (see picture). Unfortunately, I cannot recommend.

I love my Migiwata Keyless Drill Chuck! I am very pleased with the high quality drill chuck that your company produces. I do a lot of scroll saw work, so I needed a chuck that I could use for the smaller drills and this chuck is just what I needed. The delivery time was excellent. I would recommend to a friend!

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.
