NEIKO 20753A Keyless Chuck Conversion Adapter | 1/4” Hex Shank | Convert Cordless Screwdrivers into Power Drills in Seconds | for Round-Shank Drill Bits | No Keys Needed to Tighten…

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"

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!
