I took a long time deciding but ultimately settled on this rotary hammer. I recommend it for use in apartments and private houses.
As for constant professional work, I can't say.
-Not too heavy, can be managed with one hand

Legendary DeWalt Quality Still Valued
26 May 2017 
I have been familiar with DeWalt tools for a long time, and over time, this affinity only grows stronger. I think anyone who has dealt with their equipment might express a similar opinion. Yes, they are quite expensive, but even their household tools often surpass a good half of the "professional" Chinese models. In short, I don't mind spending money on good quality tools. I work in the installation of air conditioning systems, drilling walls of various thicknesses and strengths, and as you understand, without a rotary hammer, it's like being without hands. I chose this "household" model from DeWalt based on its combination of features; it may not work for an hour without interruption, but it can quickly make up to two dozen holes in load-bearing concrete walls without much effort.
From my own experience, I can say that DeWalt's 900W are worth one and a half kilowatts of pure Chinese. In concrete, it can drill with drills up to 28 mm in diameter, and it does it quickly and cheerfully, the engine pulls out such a load without really slowing down. Adjustment of speed of rotation, naturally, electronic, with soft start-up. A brick in hammer drilling mode generally goes through like butter, with almost no serious resistance. There is a slight heating, but I can work for 20-25 minutes without long breaks and this is usually enough for me. It weighs a little more than three kilograms, it holds comfortably in the hands, the handles are ergonomic, the mode switch and reverse are exactly where they should be. One-year warranty, but when registering on the site, you can extend it to a three-year one! It will be necessary to do this, but the hands do not reach in any way.
These are almost the most expensive "household" rotary hammers on our market. In fact, this amount already falls within the range of a lot of semi-professional tools from many budget brands.
Everything is fine, except for the drill compartment. It gave me a burning feeling.

A very good rotary hammer for home use, but it does have its drawbacks. First, the advantages. 1-Power. It has plenty of power if you're not doing professional work. I use a Bosch 3-28DFR at work, and if I need to do chiseling, I take that, while I use the DeWalt exclusively for drilling. 2-Case. Let me elaborate on this. The case seems convenient at first glance, but after using this rotary hammer for over 2 years, I can say that everything is convenient except for the drill bit compartment. For the person who designed the drill bit compartment, there's a special place in hell because it was too difficult for them to make it so that the compartment would CLOSE WITH A CORRESPONDING PART OF THE BODY ON THE LID!!
Power, quality, weight, cord.

Rotary hammer for installers

DeWALT D25143K is a classic three-mode multi-purpose rotary hammer. His element is assembly work. If you need to quickly make 10 – 50 holes in a concrete floor or masonry, then the DeWALT D25143K will easily cope with this task. Do you need to drill a metal corner, knead a mortar or cut a hole with a bimetal crown? The perforator is on the shoulder. But during intensive dismantling work with classic demolition hammers, he will not be able to compete.

Professional approach to the design of rock drills

Due to the fact that the tool weighs only 3.1 kg, if necessary, you can work with one hand. But it is better to use an additional rubberized handle to relieve your hands. It rotates and locks into position. A depth gauge with markings is attached to the handle.

The keyless chuck is compatible with all drills and drills of the SDS+ standard. Between the gearbox and the chuck there is a safety clutch that helps out when the tool is jammed. Given the high "rate of fire" (up to 5350 beats / min) and high impact energy (3 J), it is recommended to use DeWALT branded equipment or high-quality drills, chisels and drills from other well-known manufacturers in order to avoid cartridge loosening.

The DeWALT D25143K has electronic speed control: the harder you press the start button, the faster the cartridge rotates (in shock mode, the frequency of impacts increases or decreases accordingly). There is a button lock in the on state to fix the selected speed.

Reliable and durable, but "hard"

The DeWALT D25143K is perfect for installers looking for a reliable and durable tool for drilling holes for anchors, dowels and other fastening systems. But it is worth remembering that, despite the presence of the AVC anti-vibration system, the rotary hammer is “harsh” in shock mode. In the case of prolonged work, it is worth using anti-vibration gloves, or even better — pick up a tool equipped with an active damper.
