1/2"(13mm) Drill Chuck with 1/4" Quick Change Hex Drive and Wrench to Drill

Just what I needed, runs true, accurate chuck. Seem high quality and hardened, key fit is superb too.

I was surprised at the accuracy of this chuck as it was not a really expensive item. Worked really well!

This drill check works perfectly in my quarter inch call it impact driver, allowing me to use drillbits with the impact driver. I was able to easily drill through Brecken concrete using this combination.

This is a useful, cost effective tool but it did not "lock" into my Dewalt driver, as others have experienced. That probably won't be a problem but it will require keeping the pressure on the work. Also, the shaft fit is a little sloppy, so its not going to be for precision work. That said, it will turn a driver into a drill.

Excellent, well built, surprisingly it even came properly lubricated. Thick, heavy. Perfect.

Took out of packaging installed shaft with phillips screw. I then inserted a drill bit tryed to turn the chuck by hand to tighten down on the bit and chuck kept on binding. I finally got it secured and inserted the chuck key and tryed to tighten started the drill and bit was spinning inside the chuck trying again and again with no sucess. I decided to return the item when trying to disasemble the unit I could not release the phillips screw so I packed the unit up in the original package scotched tapped it the best that I could and sent it back to AMAZON for a full credit. DON'T BUY THIS IT IS A PIECE OF JUNK!

make power drill more versatile and change easily.

Excellent quality, just what I needed to get the job done without having to buy a bigger drill !
