Powerful motor: The DEWINNER rotary hammer drill is made to do heavy-duty concrete and metal work quickly and accurately.
In this game, there are three ways to play. The drill, hammer, and hammer drill have three different functions that can be used in a wide range of situations. It is easy to switch between them. The double function switch design can last 100% longer than a single function switch design.
People who make things that are easy to us. DEWINNER’s rotary hammer drill has an ergonomic design with a rubber and 360-degree adjustable handle that makes it easy to use. Users will be safe with the SDS-plus hammer drill because it has a well-designed heat dissipation motor and a double anti-dust bottom.
A DEWINNER rotary hammer can do a lot of drilling. Wood, masonry, concrete, and steel can use this. It can only drill up to 1-1/2 inches wide. It’s best to drill at a depth of 16/25 to 22/25 inches. There is no load on the DEWINNER rotary hammer drill, which means it can go at no-load speeds of 850 RPM and 4400 bpm.
The DEWINNER Rotary Hammer comes with a depth stop, a key type drill chuck, and an SDS shank. It also comes with 8/10/12 X 250 mm drill bits, a flat chisel (14x250mm), and a pointed chisel (14x250mm).
For now, at least. The drill is powerful and does a good job breaking things down, at least while it lasts. I’m sorry to say, but it’s not very long.
It broke for the first time after about two hours of chiseling, or even less than that. The force of the impact started to go down and then stopped. People were able to get things back to normal after giving them a lot of lubrication. This is easy because you only need to remove the large cover on top.
The next thing that broke was the chiseling/drilling rotary switch, which was the next thing to go. A lot of dust makes it hard to move. Again, dismantling, cleaning, and lubricating helped. Even though the switch was still a little stiff, it was still easy to turn.
After a few more hours of work, the third thing gave up. Do you know. The motor, the only carbon brushes, or the switch could be to blame for this. The drill didn’t work at all. At this point, I’ve had enough, so I’ve packed it up and sent it back to Amazon.
Even more bad news: The power cord on this drill is way too short. There is no way anyone would think that having just over 1m of power cord would make it hard to use the drill in most situations.
