I was just organizing shed for brew day and realized my 1500 isn't variable speed. Figured i best correct myself here Just in case anyone is misled by my post. Still an awesome renovators tool.How much extra is the OZRH1500WAK? I bought its predecessor in 06 and have done a huge amount of work with it over three renovations. It's an awesome tool and came with a chuck when you didn't want to use sds bits. So if it doesn't cost much more spring for a rotary. I think it cost me $70 from bunnings.
