I had noted in another thread that there are different terminologies in common use in different countries (and probably even in different regions) for these types of drills.
EX - In general I never see (in print) or hear "percussion drill" in the USA. Unless the source is from outside the USA. And if someone says "impact drill" I usually need to ask exactly which type they are talking about.
Here, in my experience, "hammer drill" is the non-SDS type, and "rotary hammer" is the SDS type. A quick perusal of manufacturers advertising and nomenclature will show this also.
Some people use "hammer drill" to describe both SDS and non-SDS types collectively.
And "impact driver" or just "impact" is the type specifically for driving fasteners. Or "impact wrench" being used in the automotive trade.
So this type of terminology differentiation is something to keep in mind when discussing these tools.
