Yesterday I previewed a couple of new Makita 18V brushless tools - an impact driver, hammer drill, and rotary hammer. In doing a bit of research for the post, I found a For Construction Pros video from World of Concrete 2012 where, at the beginning of the post, a Makita rep says “this is the first brushless rotary hammer.” While this may be Makita’s first brushless hammer, it’s not true industry-wide since Bosch came out with an 18V brushless rotary hammer in 2011.
The Bosch brushless rotary hammer kit (3/4″ SDS-Plus), model RHH180-01, is fairly compact and lightweight at 5.7 lbs. Due to the brushless motor’s greater efficiency, the hammer is said to have up to 25% greater runtime than competing models. Bosch says that you can drill up to 100 1/4″ x 1-1/2″ holes in masonry on a single battery charge. Max-torque is rated at 360 in-lbs, and the hammer operates at 0-1400 RPM and 0-4550 BPM.
It features an electro-pneumatic SDS-Plus impactor mechanism, which [sound fancy yet vague and] contributes to a boost in drilling performance. Electronic motor protection prevents the tool from overheating and electronic cell protection helps prevent battery overloading, overheating, and deep discharging. Additional features include an LED work light, auxiliary handle, and depth rod.
The kit includes two 18V FatPack batteries, a 30-minute charger, and a carrying bag.

Also available is the bare-tool RHH180B, at huge savings over the kit.
If 5.7 lbs is still a bit too weighty, don’t forget that Bosch recently came out with an even more compact 4.6 lb rotary hammer. No, it’s not brushless, but it’s also more affordable than the RHH180 previewed here.
