Built as an improvement to its predecessors, the cordless rotary hammer features the LXT Lithium-ion battery technology and a horde of tiny innovative features that make the use of the Makita DHR243RMJ a more pleasurable experience than previous rotary hammer drill kits from Makita.
With the more efficient brushless DC motors that cut power losses by up to 30%, the Makita DHR243RMJ makes optimum use of the last ounce of juice in its 18V 4Ah LXT Li-ion battery. The motor runs at a no-load speed of up to 950 rpm and can make up to 4,700 beats per minute in hammer mode at 2.4J on each impact. The DHR243RMJ can drill a maximum of 27mm in wood, 24mm in concrete and 13mm in steel. It also has a 3-mode operation that can be set to rotation and hammering, hammering only and rotation only.
One of the most prominent features of the DHR243RMJ is the separation of the upper body from the lower body of the rotary drill with a cushioning rubber acting as a go-between between the two parts. The rubber absorbs vibrations and deters them from reaching the user or the battery area, thus prolonging the longevity of the batteries. This is done by preventing the vibrations from causing battery failure resulting from poor electrical contact or even terminal breakage. The positioning of the handle is designed to be the Center of Gravity of the hammer, ensuring perfect handling and balance. An easy-slide SDS-Plus chunk release makes sure the transition from the hammer to drill mode is almost seamless. An easy-grip ergonomic handle makes use of the Makita DHR243RMJ comfortable in any angle it is used in.
The Makita DHR243RMJ, however, has several shortcomings. It offers a lower no-load rotation speed in comparison to other rotary hammers. It also has no LED light for working in dimly lit areas. The depth gauge rod is also not conducive for left-handed use.
