sweet, thanks for your suggestions. im looking up the dremel metal cut, ppl seem to like it universally. quick question, im on ebay right now, can you tell me all the parts there are to this dremel and metal cut off wheel? to me it looks like these circle pads as well as a handle that attaches to them. am i missing anything? and is there such thing as cheaping out on these things? their pretty cheap in price as it is. if there are any more suggestions, please! thanks!
EDIT: 1 more thing, these come in different sizes, does that mean it cuts exactly the size it says? so 4" wheel cuts 4" hole?
