Summary: I bought this hammer drill about a year after selling my bosch sds max drill that i had. I wasn't expecting to be wow'd by its performance, but after using it to drill all my wall plates in my basement i was suprised at the durability of the drill and how hard it hits. I would definitely buy another hitachi product after using this drill, and expect to be using this one for many years to come.
Summary: I wasn't aware of what SDS meant when I purchased this. Practically what it means is that you need to purchase specialized drill bits to work with this chuck system. And while I can find regular spade wood bits that work with an SDS system relatively easily, finding a masonry bit for SDS is a lot more difficult. I wasn't prepared to throw away all of my drill bits just because they didn't work with an SDS system. So I gave back the drill.
Summary: Don't believe this price: Original or reduction. The US site has original at $230 (where did they get $530 from?) and currently on sale at $60. For quality of product see american reviews below.
Excerpt: Для долбления можно применять только 4х гранное долото.Проштрабить стену в квартире можно,а в роли отбойного молотка использовать не стоит.
Cons: Нет долбления отдельно от вращения,плоским долотом нереально долбить-вращается,греется если работать беспощадно. Провода со временем оборвались-починил. Хотелось бы регулятор усилия как на шуруповерте.Был бы как электрошуруповерт.
