DongCheng 20V Max Cordless Rotary Hammer Drill, 7/8" SDS-Plus, 4 Application Modes, Brushless, 2.1 Joules, Cordless Demolition Hammer for Concrete, Including 4.0Ah Battery and Charger, 4 Drill Bits

I bought one of these drills and it performed beyond my expectations and within a week I bought another one. Good gravy for the price you just can’t beat it. I’ve been running both for a while now without any troubles. Drilling pilot holes for tapcons and sammys through steel and concrete. Blowing 1” holes through poured concrete walls. They’ve worked great. I’m not sure I’d venture to anything bigger than an inch or core bits.

Haven’t used as yet but it will definitely worth the buy

I was thinking of buying a Milwaukee, but for the price, why not try it?It gets the job done. Battery life is good, so far, and it makes 13 holes of 3/8 with 3 inches deep.

I'm an electrician by trade, I'm usually a Milwaukee tool guy, but I wanted to mix things up a little bit with my tool platform. The Dongcheng brand gives me nostalgia, because I lived in China for ten years and was quite a tool junkie back then. Dongcheng is a well established brand in China, I've used some of their power tools in the past and wasn't disappointed by them. When I picked this rotary hammer up for the first time, I could feel that it is well built, it's probably not at the same level as Milwaukee, Bosch or Hilti, but it seems like a quality rotary hammer none the less. Dongcheng is offering a 5 year limited warranty on their tools, which tells me that they stand behind their tools. I paid for next day delivery and it was here on the next day. Shipping was fast, build quality is seems good, warranty is good and it came with everything as advertised. I highly recommend buying into the Dongcheng line of tools if you want a decent quality tool for a lower price than the big box stores. The only thing against this tool so far is that it says "Dongcheng" in English, not the red letter "东城" that I'm used to seeing on the sides of the tools, but I guess that's for the foreign market. I really hope Dongcheng starts selling their tools in stores here, I miss walking into Dongcheng shops and checking out the tools that they have...

It is a nice quality product. The only thing is that it is too light for my use, The battery depleted pretty quick and it takes a little north of two hours to fully charge it again. If you intend to use it on an occasional basis, go ahead and purchase this, it is perfect. If you are like me, Contractor either purchase another battery or go with a corded product

Runs like a champ. Pounds rebar into degenerate granite. Breaks up cement. Powerful. Batteries are big. Instead of calling China our enemy maybe our politicians should study what China is doing right. Singapore is their model. This company makes a lot of other brands as well. From the battery it looks like they might be making Milwaukee tools.

Don’t waste your money on this hammer drill. Poor quality and not strong enough. Also the battery doesn’t last enough. It last less than 10 minutes

I was a little nervous purchasing this drill, but for the price I figured I would give it a try. I can say that I have been pleasantly surprised with the power of this drill. I have used other hammer drills in the past when drilling holes in concrete block that dont have near the power that this drill has. With the hammer drill setting on it goes through concrete block like butter. I have been using this to drill holes to put up hurricane panels and it has made the jobe so much easier. I would definitely buy this again.
