LABEAR-Keyless Mini Drill Chuck Adapter, 1/4" Hex Shank Quick Change Micro Drill Bit Holder, 0.3-3.2mm Precision Chuck Converter for Cordless Screwdrivers, Impact Drivers, Electric Drills & DIY Tools

I'm not a pro, but the item seems to work fine; it is able to securely hold a #80 drill bit (0.34 mm) as advertised. However, parts of the item description are either unclear or incorrect, so to clarify: (1) I received ONE drill chuck, which is the smaller of the two (50 mm long) pictured in the second photo. (2) Based on extensive materials analysis (aka checking with cheap refrigerator magnet) all parts of this item are made of different types of steel, NOT aluminum. (3) The mass of the item is 13.6 grams, NOT 0.02 kg. (4) I don't believe the description mentions country of origin, so FYI the inner packaging of the item indicates that it was made in Taiwan.

Works great for what it’s intended for, I seen some reviews complaining it broke well it’s not meant to go hog wild with large bits, this is a great attachment for small drill bits and it works as intended.

This really helps with very small drill bits but it seemed to be off just a minute amount from being perfectly centered. Still worked well for my purpose.

Excellent quality for drill bits from 1/8in to zero when using a 1/4in drill

My drill press chuck can't grip the smaller bits in my 0-60 numbered drill bit set. This adapter solves that issue. I have not used it yet, but the adapter appears to be well made.

Only good for light duty drilling. It did not hold the bit for light metal.

Very pleased with it, used it extensively today holding bits from anywhere from .030 to .060. I read in some reviews that it would come loose so I used pliers to give it an 1/8 turn once tight. Only other thing to watch is depending on the medium you’re working with, I did have the jaws get a little gummed up with rubber adhesive. I took the drill bit out and used that to get the crud out. I did about 250 holes just today with it. Very happy, considering a .035 drill bit doesn’t even fit in my Milwaukee M18 1/2 Hammer Drill.

The mini adapter does not handle a 1/32" drill bit gracefully. Even after resetting it several times the chuck could not grip the bit in a way that allowed it to drill a hole. The bit it was gripping span for a little and then the chuck rotated around the bit in question and just polished its backside. Even when i feathered the input on the lowest settings to give it a chance to pilot a notch for itself it couldn't overcome the friction when too much of the bit was surrounded by material. I applied the same 1/32" bit to the larger1.5-6mm Alloy LaBear chuck I happened to also purchase from this page and it worked flawlessly despite a 1/32" bit being outside its suggested size range. While a 1/32" bit is about 0.8mm so I have very little faith this will gracefully machine out more narrower applications with mini cobalt bits.

Producto que cumple con las necesidades y buena calidad.

Dieses Bohrfutter ist gut verarbeitet. Leider eiert es ein wenig.

Thanks

Im just using it to hold micro drill bits for carb jets. The chuck jaws lined up perfectly, holds them well. I use it by hand.
