SOURCE: hammer drills and rotary hammers comparison
Basically yes. Lower power units are usually titled as "hammer drills." Higher power units, usually labeled "rotary hammers," tend to be larger and provide bigger impact forces. But there are a few differences that are worth knowing: The rotary hammer usually have a chisel only feature, for light chiseling and masonry removal. Rotary hammers also have specially designed chucks that only accept bits specifically designed to fit their chuck. The special chuck on a rotary hammer helps hold the drill bit and prevents it from slipping during use.

look at the back of the brush holder for a tab that the forward/reverse lever locks into, it might be broken not allowing it to shift.
SOURCE: hammer drill only works when you tap on it with a hammer
Yes, check the brushes on the motor, see if they can be replaced - I don't know your drill, but some can be checked without pulling the case apart - look for a round slotted cover on the sides near the rear of the drill
SOURCE: drill keeps on stopping and won't restart
Check the cord...sometimes if the brushes are not seated well or if there is a cut in the cord you will run into that problem....If it is not that then possibly you just have a faulty drill

Inside there is a little plastic shaft, where the selector hooks to. They have had problems over the years stripping. Replacement part is still plastic. Yay! You may need a bearing puller or find some way to get the clutch off the shaft. Lemme know. Please rate me
