DongCheng Hammer Drill 6A,1/2 Inch Keyed Chuck, 0-3000 RPM/45000 BPM Impact Drill with 15PCS Drilling Bits for Concrete，Metal & Wood, DZJ05-13

For the price, this item was incredible. Not sure about the longevity of it yet but worth it for the price either way.

Took a chance on this and am thoroughly impressed. If you let 'er rip, she'll run straight through concrete no problem. The bits it comes with are, as expected, not great and will break after a few runs through concrete (hence the minus one star on durability), but no biggie there. Used it for multiple projects so far and has had no issues. Feels super sturdy, built like an old school drill from decades past. I especially like that it comes with extra brushes for the motor - very cool that a company is still making serviceable tools like this. Feels kinda goofy walking around with a tool branded "DONG CHENG" when you've got name-brand tools sitting next to it, but hey, it does the job, and can't beat it for the price.

Bought this to drill a hole in a boulder for a project. It worked but not sure of longevity for this drill. I bought it to drill a hole (which it did) but this is clearly a cheapo hammer drill that did the job for me.

Muy buen equipo y marca, ya libro su costo hace rato, es potente para trabajo en metal hasta 3/16

This is a solid heavy duty drill. Very impressive quality!

My first impression was positive as the drill had good power, and using it on the hammer setting with only a 1/8 inch drill bit, drilling a few holes in a concrete block was a breeze. Unfortunately, on only the second use (3 months after purchase) and using it with a 2 inch hole saw just a single time, the chuck fell off! The chuck is threaded onto the drill arbor but they use a tiny screw, apparently made out of pot metal, to keep the chuck securely in place. With just a little stress with the larger drill bit that screw snapped off rendering the drill useless, as the chuck will just unthread itself in normal use without that screw. Unfortunately, part of the screw is now snapped off and stuck in the drill and it would require a very small screw extractor to take out, and then getting a replacement screw from the manufacturer, to fix it. There are two problems with this drill that I can see just from this one issue: 1st, the screw they used is undersized to hold on the chuck of a 6 amp drill. Secondly, if they were going to use such a tiny screw then they need to make sure the screw is made from high quality titanium steel. Since my purchase is beyond the return date, the only thing I can hope for is that the manufacturer will contact me about getting a replacement. If that happens I will change this review rating, and hope that the next drill is better.

My old drill just wore out after 2 decades of dedicated service. Replaced it with this one. It made me forget my old one immediately. It does everything better, especiallydrilling through concrete!

Was easy drilling into the concrete block. Took no time at all. The only issue is that the stabilizing handle kept coming off. Other than that it's a great buy for someone like me who doesn't need it very often
