Model HR2811F is a versatile, high-powered rotary hammer with an L-shape design ideal for horizontal work. The hammer accepts SDS-PLUS bits, and is powered by a 6.7 AMP variable speed motor delivering 2.7 Joules of impact energy. The HR2811F features 3-mode operation for “rotation only”, “hammering with rotation”, or “hammering only” for multiple applications, with 0-1,100 RPM and 0-4,500 BPM. The torque limiting clutch prevents gear damage by automatically disengaging gears if the bit binds. The HR2475 has an LED light for improved illumination of the work surface. Makita rotary hammers are engineered with the Makita Motor Advantage, which features field core interlocking steel laminations, dual ball bearing armature, and more copper commutator bars. These engineering points-of-difference increase the energy transfer efficiency for more power and longer tool life. Also included in the HR2811FX is the Makita 4-1/2 in. Angle Grinder. The 4-1/2 in. Grinder has a 7.5 Amp motor for high power output and 10,000 RPM for a range of grinding applications.
Powerful 7.0 AMP motor delivers 2.1 ft.lbs. of impact energy to handle the most demanding applications
Vibration-absorbing back handle for operator comfort
L.E.D. light illuminates drilling surface for more productivity in low light applications
Torque limiting clutch engineered to prevent gear damage by automatically disengaging gears if the bit binds
3-mode operation for "Rotation Only", "Hammering with Rotation" or "Hammering Only"
-----I was weary about getting this small rotary hammer drill, but i'm glad I bought this one opposed to a larger model after having a chance to use it allot. I am not a contractor, but used this to pull up 4 layers of linoleum glued to my slab. I pulled it off of my kitchen floor in about an hour. I then chipped the floor with it to get the glue off and actually broke a chisel due to fatigue. I also used this to pull sheet rock that was glued to a few large headers and also drill 5/8 dia holes in concrete (a little slow, maybe 15-30 seconds but ok if your not doing them day in and day out). I also used it to break up stucco to put in a few new windows. The reason im glad I bought a smaller hammer drill is that it would have been too cumbersome to do the above with a large drill (except drilling the hole). I think there is a place for a small rotary hammer drill and a large one, but for the homeowner, a smaller one will be a better selection because it doesnt weigh that much and will see allot more use.----I would also recommend getting a "sds plus to 1/2" chuck adapter" and a "jacobs chuck" so you can use this a regular drill if you only have one drill. I wouldnt recommend using the chuck adaptor and a jacobs chuck in rotary hammer now to drill small holes with masonary bits that do not have sds plus shanks. You will end up breaking the chuck, I broke a chuck on the very first 3/16 hole I tried drilling.----I hope this review helps someone.
