Buy Bare-Tool Makita BHR202Z 18-Volt LXT Lithium-Ion Cordless 7/8-Inch SDS-Plus Rotary Hammer (Tool Only, No Battery)

My review is actually for the D-handle model of the otherwise identical tool.

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.Get more detail about Bare-Tool Makita BHR202Z 18-Volt LXT Lithium-Ion Cordless 7/8-Inch SDS-Plus Rotary Hammer (Tool Only, No Battery).
