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

So much power in such a lightweight package. Low vibration but solid torque. I'm actually going all in on this brand. DongCheng makes some good quality tools. I was always a diehard fan of the big name tools like dewalt and Milwaukee but DongCheng can compete with those big brands easily at less than half of the cost in most cases. Great value for money

This is a very good Cordless Rotary Hammer Drill. It works very well in drilling concret wall, and come with everything you need : drill bits, powerful battery, and a charger. It used to take me hours to drill concret wall with cord or cordless drill that I have for just 12 holes. Now, it only take me 5 minutes on less for the same amount of holes. On top of that, I can replace my other cordless drill with this powerful one for any other drilling. This machine has 4 functions: Drill, Hammer Drill, Demolition Dril, and another one that I am not sure what is for.

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

So far, I have only used this to drill small holes in concrete paving blocks (16x8x2) to install screws to hold down a storage building. It worked great. It seems very sturdy. I have a chain saw from the same company (which I like a lot) and it uses the same batteries, which is nice. This is my first time to use this type of device, but it worked very well for me, and the price was very good.

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.

As a first time sds user am impressed with the power of sds bits to penetrate concrete compared to a regular cordless hammer drill with chuck. The possible drawback of not accepting regular bits can be overcome by getting an sds drill chuck adapter for non hammer use only. Could drill about 10 1/2"x6"deep holes in hammer drill mode before the battery was down to 50% or 2 out 4 LEDs. This is probably when I am ready for a break. The charger shows a red light when charging, green steady when charged, and green blinking when battery is removed. The battery 4 bar led is a nice indicator of remaining charge. Like almost all tool brands this uses a unique style of battery. It would be an advantage if you could interchange batteries. After using this for over a year, it's been a good if somewhat heavy tool. It offers a 3 or 5 year warranty to consumers if you register.

I was unhappy when I opened the box as it did not have a user manual but I still figured out how to operate the Rotary Hammer. The description mentions four bits will be shipped with the user manual but the smallest size bit and the user manual were missing in the package. When I tried to use a smaller size drill bit which was smaller than the one not included in the package, It would not work. There is no mention in the product description that specific type of bits will work with this rotary hammer.

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...

Es el segundo que compro porque el primero me salio muy bueno y necesitaba otro

Very bad
