Thanks All.

On the matter of the power, the potential difficulty in using a 3.5+KW machine with a regular extension lead was my main concern. If a 1.7KW is up to the job of dealing with most DIY breaking tasks, then I will probably stick with that.

With regard SDS, SDS Max etc.- yes, I think I used the wrong term. It's a hex shank breaker that I'm after.

Regards.
