Makita DHR171Z reviews
It integrates a powerful motor with BL technology, which provides brushless operation, to favor the lightness of the equipment and a long useful life. Similarly, it prevents energy losses to reduce heat production during use.
It does not include a charger, but it is possible to get it separately for an affordable price. Either way, the tool is compatible with same-brand chargers and batteries for added versatility.
This equipment offers a maximum capacity of 17 mm in concrete, 10 mm in metal and 13 mm in wood, which indicates a good performance. Also, it doesn’t cost too much money.
Main Features Explained
It is one of the best percussive hammers according to the opinions of some users, since it incorporates an LED light pointer capable of providing optimal lighting in the work area, which is very practical, especially if you use the tool in light places limited. Similarly, this feature can improve accuracy when doing professional-level projects by allowing you to better position the fixture in the desired contact area, avoiding drilling the wrong area on the surface.
For greater practicality, it has a tool holder with a quick insertion system SDS Plus, indicated to change the drill in a comfortable way, which favors ease of use. Additionally, it offers two modes of operation, rotation and rotation with percussion. In this sense, the percussive rotation mode is capable of delivering up to 4800 gpm, which provides great speed for removing and breaking tiles, concrete, etc.
For its part, the rotation-only function can offer speeds of up to 680 rpm, enough to drill surfaces of wood, metal, among other materials. It is important to mention that the trigger has a variable speed system to adapt it to your needs. Also, it offers a reversible mode that allows you to rotate in the opposite direction for greater versatility.
engine and battery
To guarantee optimal performance, this equipment is made up of a brushless BL motor, which avoids friction to reduce the heat produced by the tool, thus lowering the temperature of the casing, gears and other elements in the lower area of the structure. In this way, the motor protects itself from overheating, which allows you to use it for long work days at an industrial and professional level. Likewise, this reduces breakdowns, which saves money and provides a long service life.
It is important to mention that the motor is powered by a Makita brand 18V lithium-ion battery, which is 40% lighter compared to Ni-Cd and Ni-MH batteries, which reduces the weight of the tool.. Additionally, the Lithium-ion cells have no memory effect, which allows you to charge the tool at any time without reducing its useful life.
For added durability, the internal structure of the battery is covered with a layer of rubber that absorbs shock in case of falls and has an internal design that allows airflow. In this way, it can provide faster cooling.
One of the most outstanding aspects of the design of this hammer is its body divided into two parts, capable of considerably reducing vibrations between the motor of the device and the handle, which avoids discomfort in the hands and joints when used for a long time..
In addition, both the front and rear handles are covered with anti-slip material, which allows you to hold the tool with greater security and confidence. Also, this provides more control over the movements of the tool. As for the rear handle, it is shaped like the letter D, which provides a more ergonomic design to hold the hammer comfortably.
To the left of the chuck, this tool has a depth stop with an adjustable length from 1 to 24 cm, in this way, it gives you greater precision to carry out drilling or demolition work on any type of surface. On the other hand, this is one of the most compact and light hammer drills of its kind, since it measures 27.3 x 8.6 x 21.1 cm and weighs only 2.8 kg. For this reason, it is possible to use it on long working days.
