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.

Easy to release, good quality, it looks like it will last. Fit perfect in my Bosch screwdriver. 4 stars as its kind of stiff to close it and grip the drill bit.

Works as intended.

Com furadeira de impacto, da pra fazer muitos trabalhos com essa peça. Creio que para serviço mais pesado ela ñ aguente. Gostei!!!

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"

This is a nice little chuck. I some times use very small drill bits for some of my projects 2 or 3 mm (1/16 -3/32) my regular chuck wont hold them. Years ago I bought a chuck for a Dremel tool, a replacement chuck and machined a shank to fit it. I actually used to use it in the 1980s with my old 6v battery operated screw driver which didnt have the torq to drive the screws in so every hole had to be predrilled. I used this old chuck for over 30 years and I came to depend on it for more precision work later on, and now use it mostly on my 20v driver and sometimes in a 1/2" drill press. I was making my grandson a display case for his pocket knives and needed to predrill holes for small brass screws, but I lost the Dremel chuck some where, so I ordered this one which is a bit heavier but also grips the bits much better and fits in the driver much better, the old one, with the home made shank, it wouldnt lock into the driver so would some times it would fall out.. You can change bits in seconds when drilling different size holes or replacing broken or dull bits. Now you should remember this is not for real heavy work. I have used it in my small drill press for some precision work. But mostly use it in my driver and like I said, usually only for very small drill bits, in oak up to 1"thick or lite guage metal. It grips the bits much tighter then the dremel chuck. I have used it for 1/8 bits but only cause I was to lazy the grab my drill. Its well worth the small cost.

Excellent product
