Last year I bought a Makita HR2470 for home use from German Amazon, because it had many positive reviews. Since then many negative ones appeared saying that the drill bit wobbles. There is also a user video on their site. It is an SDS-plus drill and I have an adaptor to use normal round bits too. With this I have put a ball pen in it, and touched to a paper when the drill was on, without the hammer function. It made a split pea sized circle on the paper. I also have a Bosch GBM 1600 RE normal drill. This leaves only a point on the paper, as expected.

Recently I have made with the hammer drill + adaptor holes in tile, and did not know why the tile was chopped around the hole.

I have two questions. Is this a property of hammer drills, they are less precise or mine is defective? I actually sent it back, and now I am looking for a different model. Do you know any hammer drill without this problem? I understand if a more precise tool is more expensive than this.
