DWT rotary hammers (DVT)

Unfortunately, I covered myself in a couple of days of work (I worked for an hour or two a day, and then with small loads). It works, but with a small load it does not twist the drill, but simply bursts.

Beautiful appearance.

Covered up

I work in the construction industry, and I can’t do without a punch here. I chose the VN-850 BMC model from DWT, initially I was worried for a long time, I took it for quality of work, I used it several times, I used several types of machines, many simply could not cope with the intensity and simply broke. But my purchase simply pleased me.

There is a lot of good in it, now I will tell you the main advantages: it’s done qualitatively, overheating even with constant work does not happen, the power is just excellent, the weight is normal, the hands do not jam, there is an emphasis on the drilling depth, it has never broken in four years of operation, it's just fantastic! The operation is simple, you only need to occasionally lubricate it. For me, this is the best hammer drill of its kind, it simply has no shortcomings. I recommend, take a closer look at this option, it's good!

Not!

Just recently, my wedding flew by, examining gifts I found that one of my friends gave me a DWT BH-850 BMC puncher. The puncher was very useful in a new apartment when installing curtains. It is very easy to make holes in the concrete of the load-bearing wall, despite its “mini” dimensions, it has a very significant strength. It’s very convenient for them to work, since it is very light, which makes it possible to work at a height with outstretched arms (hands almost never get tired of it).

I hollowed them with technical holes with a diameter of 14 centimeters and a depth of 30 cm, for this hole I needed only 25 minutes. For such a miniature punch, this is a pretty significant indicator. All the mechanisms of the punchers are well lubricated and maintained, I have been working it for 8 months, the grease on the parts still remains.

Not afraid of dust, miniature size.

I did not see the flaws.

It has already been 6 months since I purchased the DWT BH-1200 BMC rotary hammer. When I bought it, I pursued several goals: the price that was optimal for my pocket (I took it for 2300 rubles) and powerful impact force. This punch, fully met all my expectations. The blow was excellent, without any problems, it made him 46 meters deep grooves, in a 25-cm cement-sand screed, the puncher after the work was a little warm.Then he gave him a more serious load, in the form of a shtroba, already in a concrete slab, as it seemed to me, the puncher “did not notice” any difference in material, he also made the shtrobo well, but he just warmed up thoroughly. The puncher works like a clock, for all the time it has no complaints.

low price, powerful blow, practically does not heat up.

a very uncomfortable form of the case, when you press a button, it tries to press your finger.
