"Amazing power for a cordless." 2010-04-15
By S. Wysong
After foolishly trying to drill 3/4" holes in concrete with the LXT Hammer Driver/Drill, I ended up with a 1" deep mess.
I got the BHR240 and the difference is amazing. With very little effort I had two 5" deep 3/4" dia holes in less time than it took to drill the 1" deep mess from earlier. The holes are amazingly smooth and the drill is easy to contol. I'm pretty sure my 7 year old could do it. As others mentioned, the power to do this to concrete has to come from somewhere. My 4 year old 18v LXT batteries start to fade after two holes (3/4" x 10" total). So, if you were doing this all day you would need 2 chargers and 3-4 batteries. Alternatively, I believe Bosch has a 36v model. Me, I am already invested in LXT tools and have been happy with every one, including this one.
"Almost as good as a Bulldog" 2009-06-14
By Josh
I've been using a Bosch Bulldog for about 7 years. I got the Makita BHR240 as a mail in rebate from Makita for buying their LXT702 kit from Amazon. It's almost every bit as powerful as the corded Bulldog, and works great for smaller size holes. Combine this tool with a Makita impact driver, and you've got an ideal cordless solution to driving Tapcon fasteners into concrete and masonry. The part of the tool that accepts the battery is mounted on rubber to insulate the battery from vibration, and feels a little bit too loose. The battery still can vibrate against the tool itself. I think Makita could have put a little more work into their battery mount on this tool to better isolate the vibration. Otherwise, i'm very happy with my free tool!
"great portable rotary hammer" 2009-02-15
By StevieQ (Castro Valley, CA United States)
This Makita LXT 18v Li-on D-handle rotary hammer has 1.9 joules (or 1.4 ft*lb) of impact energy at up to 4000 blows per minute. By comparison, Makita's corded version has 2.7 joules (or 2.0 ft*lb) of impact energy at up to 4500 blows per minute, making the cordless version about 70% as powerful as the corded version, which isn't bad. I can't complain because the trade-off for portability is power and speed.
I bought this cordless rotary hammer specifically to drill 5/8" holes in concrete to set anchor bolts for my deck's footings. I can drill each 5/8" hole up to 6" deep in a minute or two, but it drains the battery at a fairly quick clip. My rough recollection is that it can only drill at most 2 of the 6"-deep, 5/8" diameter holes before the battery needs recharging. Based on my experience with the 5/8" holes, I have no doubt it is capable of drilling up to 7/8" holes.
I also used a 1" chisel bit on it and it worked really fast to chip concrete to set the footings. All in all, I am happy with this purchase despite the short battery life.
"Can't believe this is battery powered..." 2008-07-18
By Custom Finish Carpenter (So. Cal., USA)
I have used this rotary hammer drill for up to 3/4" holes in concrete and tile and it is nothing short of awesome. I also own the Bosch Bulldog, which is the industry standard in small rotary hammer drills, and this cordless Makita performs right up there with it, making short work of whatever I put it up against. While the Bosch is a great hammer drill as well, the portability of the 18 volt Li-Ion Makita really makes this drill shine, highly recommended for anyone who requires a portable rotary hammer with enough power to do the job.
