With a powerful 4.5 amp motor that delivers 1.03 ft.Lbs of impact energy, this tool can handle even the toughest applications.
An engineered torque limiting clutch is designed to prevent gear damage by automatically disengaging gears if the bit becomes stuck in the clutch.
The variable speed trigger allows the user to match the speed of the trigger to the application, resulting in greater versatility.
For dust management, use the dust extraction cup that is available, which includes a side handle SPACER, a side handle base, and a bolt.
There are two modes of operation: “rotation only” and “hammering with rotation..
Its compact and lightweight design, the Makita HR1840 11/16-inch rotary hammer (which accepts SDS-Plus), makes it an excellent choice for concrete drilling. The HR1840 provides more efficient hitting in a more compact package, allowing for faster and more productive work to be completed. The HR1840’s compact size and high power-to-weight ratio make it an excellent choice for overhead work and applications that require close proximity. The HR1840 is equipped with a 4.3 amp Makita-built motor that delivers a No load speed of 0-2, 100 RPM, with an 0-4, 800 BPM and 1.4 Joules of impact energy at zero load. For a variety of applications, the two-mode operation includes “rotation only” and “hammering with rotation” options. The HR1840, like the rest of Makita’s rotary hammer lineup, is engineered to take advantage of the Makita motor’s superior performance. The addition of field core interlocking steel laminations, a dual ball bearing armature, and more copper commutator bars are all part of the upgrade process. These characteristics ensure the most efficient transfer of energy, resulting in increased power and longer tool life. An additional performance feature is a torque limiting clutch, which is designed to prevent gear damage by automatically disengaging gears if the bit becomes clogged with dirt. An ergonomic “pistol-shaped” handle with a rubberized soft grip for increased comfort is among the features that contribute to comfort and ease of use. Among the other features are an easy-to-use one-touch sliding chuck that allows for quick bit changes, as well as a large trigger switch with recessed lock-on button for continuous operation. The longer the life of the brushes, the less downtime and the more work that can be done between service intervals. Masons, remodelers, electricians, maintenance crews, and general contractors will find the HR1840 to be an excellent tool.
I’ve owned hammer drills in the past and used masonry drill bits with them, but I’ve mostly just sat back and watched as they polished the stone or concrete. For one hole, I would have to take the drill out and slam it back in, which would take me half an hour and cost me half an hour. A few weeks ago, I attempted to drill a few holes in a concrete wall but kept hitting a stone and becoming stuck again. So, I decided to rent a tool from AGGRESSIVE PROFESSIONAL DRILL TOOLS, or so they claim, and they rent me what I believe to be a pile of junk that looks exactly like this. Unfortunately, they do not rent out the parts to you as well, so I had to purchase two of them from them. Anyway, after spending $80 and bringing this item home, convinced that it was not going to work for me, I ended up drilling the holes in mere seconds. The drill was so smooth and easy to use, that I went outside and tested it on a piece of granite that I had attempted to drill a hole through five years earlier and it went through like butter. My first impression was so good that I decided to buy it even though I already had two drill bits and it didn’t cost much more than a day’s rental at Home Depot.
