FIRST OF ALL SHOW ME ANOTHER DRILL THAT HAS THE 4 FUNCTION FEATURE. . . . yea I didn't think you could, so bravo for Makita on that important point. If you don't care about doing an efficient project don't worry about getting this tool. I love efficient and streamlined work so naturally I enjoy this product from Makita. I have used this drill on a daily basis for about 2 years give or take in commercial enviornments and I am satisfied with what I have purchased, the ability to both hammer drill and impact drive in one light, slightly inconveninet package (and I only say that because the difficult gear changing). With this drill you sacrifice some power and tork but the benifits depend on your specific use each day. On most days I did not need to bring any other drill, once in a while I would have to bring my 454 Makita to do heavy penetrations (like one inch holes through concrete) but on an all around regular use day I only needed this tool.
Hey you have to get the right bits for this tool, duaa! Lowes carries 1/4" drive masonry bits and they are not that expensive and if you have some brains in your scull you can figure out that the bosch concrete ancor drive kit has a toob with a 1/4" drive socket in one end and a socket on the other end that will drive tap-cons (concrete screws I think they are usually 5/16") any way once you get all this together you can move fast on many projects only having to carry one drill.
This drill will not do well if you try to use it on structual concrete (high density) and you can not use a chuck adaptor to hammer drill, the drive function is not enough to hammer the assembly. Step bits in the adaptor are ok but again you have less tork (though there are two drilling speeds so really it's like a 5 function drill) so I have an old step bit that I used on impact setting and that gets through most stuff. The gear shifting is something that Makita really needs to work on. It is hard to shift nice and clean to get the function you want but after you get good at fighting and trouble shooting this obstical it is a minor glitch in an otherwise fast and smooth day of drill/driving.
On a high rise building where you are climbing multiple flights of stairs with all your tools daily this drill is a must have because you only have to worry about one drill not an impact driver and a drill, less to lose and less weight to carry. If this drill will fit your specific task and you use it daily it is well worth the money and I can't wait for a smoother shifting slighly more powerful model from Makita, an awsome drill non the less.
