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

This hammer drill did the trick for me. I only needed to drill around 20 anchor's in concrete. I was going to rent a hammer drill, but it turned out to be cheaper to buy this hammer drill than rent one. So instead of renting I bought this. Now I own a hammer a drill! The hammer function works great, it plows through concrete like a boss. Be sure to dial down the rotational speed of the drill. For hammer drilling you want less rotation. Use the little dial on the trigger to dial it in. It came with a tone of bits. I I've already used a couple of them for other projects. Great vlaue for the money. And as far as I can tell, it is durable.

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.

It's not even in the makita or milwaukee ballpark, but I'm not drilling into concrete for a living.

Quality equipment..affordable price

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.

I needed it to make four holes in cinder blocks. I heard the hammers and it banged through the block easily. And, since my need was so modest, I wasn't going to spend hundreds on a rotary hammer drill. I wanted a very competent, well built, and corded hammer drill because I understood that a corded one would be stronger, in general. For under 32 dollars with a coupon, the DongCheng Rotary hammer drill fit the bill. Even though the drill bit slipped a little in the keyed chuck, I still gave this drill a 5 rating, because I chalked it up to MY error after reading a review which stated that the chuck slipped for another user. You really must crank it down hard to succeed using all three holes on the chuck. After doing so, the last two Tapcons went in perfectly. If you slip the switch to the right, you've got a variable speed drill. Most homeowner DIYers can stop right there, now owning two of the three drill functions in one tool. The only function left is an impact driver. This unit is not an impact driver. I'm very please with myself for this considered purchase.

Hammer drill works well but the included drill bits are garbage - had to buy Bosch to get the job done!

Realmente el taladro es bueno 👍
