NEIKO 20753A Keyless Drill Chuck for Impact Driver, Chuck Conversion Adapter, 1/4” Hex Shank, Convert Cordless Screwdrivers into Power Drills in Seconds, For Round-Shank Drill Bits, No Keys Needed

Excellent chuck for 1/4" hex shank bit screwdriver or similar driver. Purchased for the use of smaller diameter bits so I could get the clearance needed in smaller places in which my full-sized drill could not fit. It measures right at 3 inches when fully closed and works perfectly with my Vessel screwdriver. This drill chuck is not made of cheap material like some of the others in which reviewers have indicated possible aluminum bodies and the holder having fractured under light torque. This one appears to be made of carbon or steel alloy and a magnet will definitely attract to it. Another giveaway of its construction is that it weighs close to 3 ounces. I was able to secure the smaller thickness of a sewing needle and even up to a 1/4" diameter drill bit. Very pleased with this Neiko brand!

Works as it should, better quality than expected. Easy to use, and helps get into some tight to reach spaces.

Handy Chuck Adapter with Some Limitations I picked up this Neiko keyless drill chuck to get more flexibility out of my cordless impact driver, and it does the job reasonably well. It lets me quickly convert the driver into something that can handle regular round-shank drill bits without needing a separate drill. The 1/4" hex shank makes swapping tools simple, and the keyless design means no fumbling with extra parts—just twist, tighten, and you’re set. That said, it’s not perfect. While it holds bits securely for lighter work, I did notice some wobble with larger bits or when pushing through tougher material. It’s definitely not as solid as using a dedicated drill, so I wouldn’t recommend it for heavy-duty applications. For small household projects, quick holes, or when you don’t want to drag out another tool, though, it’s a useful accessory to have on hand. Bottom line: A convenient, budget-friendly way to expand your impact driver’s capabilities, but best reserved for light to medium duty tasks.

I have several "full-size" DeWalt and Ryobi drills that I use in my shop. Here, I needed something to use inside my home on small craft projects. Mostly, I use small, numbered, drill bits so the 1/4" chuck limitation here was not a problem for me. I planned to use this chuck in smaller Ryobi and Black and Decker battery powered drills as torque was also not an issue. These smaller drills do not have chucks but do accept 1/4" hexagon bits like the shaft on this chuck. This chuck, and other 1/4" hexagon bits, have a "locking" feature near the end of the shaft. My Ryobi uses this feature to retain a bit while the Black and Decker uses only a magnet to hold a bit in place. Sometimes, when using the Black and Decker, this chuck will pull out when I'm backing the drill and chuck out of the material. So, I prefer to use the Ryobi. The only other thing to note is that there isn't any easy way to hold the chuck's shaft while you tighten the barrel around a drill bit. One could use a wrench to hold the shaft, but, so far, I have not needed to do this. However, I'm reluctant to tighten the chuck to the point where the drill motor starts turning because you can sometimes damage internal gearing by manually turning the output. I think that's why my other, larger, drills have a "locking" position that is supposed to be used when tightening the chuck.

I've had mine for about 2.5 years. It finally broke so now's the time to write a review. I bought this to be able to attach standard drill bits to the end of a flexible 1/4" flex drill extender for working in tight areas. It ultimately failed by having one of the tips of the claws break off. Pros: * It's pretty much as compact as something like this could be. * Lasted 2.5 years with frequent use. * Holds smaller drill bits well. * Works reasonably reliably. Cons: * There is no solid way to grip the body to get leverage against the chuck. This can result in bits coming loose or binding in the material being drilled. * Design works by having weird spring mechanism push the claws apart which are forced together by rotation of the chuck. This means that should a claw get stuck to the bit, rotating the chuck will not provide any force to release. * The chuck threading is very rough. This isn't a functional issue but it is concerning. * Mild eccentricity makes it more likely small bits will break and it limits precision work. Not generally a problem for routine work, though.

Most drill motors with a 1/2" chuck that I have owned will not hold a bit smaller than 1/16". Because I use number one and number two wood screws for a few projects, I need a drill with a chuck that will hold a 1/32" bit. This mini-chuck looked like it would fill that role. Alas, t'was not to be. First, I put it in my 1/4" impact driver. It wobbled, as in would not spin true. Thinking there may be a little play in the driver, I put it in my 1/2" drill. It wobbled. Next I put it in my 3/8" drill. Still wobbled. Since any drill bits I chuck in the drill motors spin true, the problem is in the mini-chuck. I tried several different sized bits, even simply loosening then retightening the mini-chuck. Although the degree of the wobble would change some, it never did spin true. Seems to be little or no quality control during manufacturing.

This is great, because it'll let you chuck tiny bits, smaller than 1/16", for things like drilling pilot holes for #4 and #6 screws. Not all full sized drills will hold a bit smaller than 1/16", and it's a pain to have to get out a dremel, and not everyone has an adjustable chuck for those. I wouldn't fault it for not being all that useful for large bits in impact, because that's a bit of a hack anyway. Get a drill for drilling things, use a driver for driving things. The bits themselves aren't designed for it.

Works great

Bought this to go on my impact driver for times when I have to switch between drilling and driving screws in, keep having to change from drill bit to driver many hundred times a day was a pain, so this does the trick. It feels solidly made, and has a professional feel to it, it will only take drill bits up to size 8, but that’s all I needed, if you need larger drill bits you will need to find a larger chuck. Haven’t used for long but does the job and feels like it will last a while.

O mandril de conversão da Neiko, sem chave, é uma ferramenta de construção robusta e que apresenta uma usinagem perfeita, que confere ao produto um excelente acabamento. Quanto à sua aplicabilidade, esse mandril, com haste de encaixe sextavado com 1/4", tem a capacidade de converter uma simples chave de fenda, manual ou elétrica (com ou sem fio), em uma pequena furadeira com muita versatilidade. Há no mercado produtos similares com preços mais em conta, mas estão muito distantes da qualidade apresentada pelo mandril da Neiko que, a despeito de ser mais caro é, sem dúvida, não só o melhor, mas, também, o que apresenta, a médio e longo prazo, a mais satisfatória relação custo/benefício.

Excellent Good

Me permite usar brocas de 5/16", de las que tienen bastago triangular, al límite y con poco agarre, pero eso ya supera su capacidad. El accesorio trabaja muy bien con brocas de 1/16" hasta 1/4"

only used it once quickly and did what its supposed to. nice and solid, packed in a box also. thx
