Sorry if this is a really stupid question but can anyone tell me if this bench grinder with flex shaft http://www.ebay.com.au/itm/BRAND-NEW...item20cde4e2f2 will do the same thing as this flexshaft with hanging motor kit and handpiece? http://www.ebay.com.au/itm/Flex-shaf...item53e748b5f0

They both have a rotary hand piece and I just really want it for polishing and a bit of drilling of sterling silver and gold pieces.

I'm guessing with the bench grinder I will be able to buy some polishing wheels to put in where the grinding wheels are and polish some pieces like that?? And I assume that the hand piece thats in the bench grinder set can be used to polish and drill?

Ahh sorry I dont even really know what other qeustions I need to ask. Just if anyone can help me. I don't need anything expensive like foredom or do you think i shoudl invest in a foredom flexshaft system? Argh so confusing!
