30 mm Arbor

Does anyone have any information on machining out saw blades holes. I have a table saw with 30mm arbor which reduces my choice on saw blades. I'm interested in the Freud blades but as far as I can find out they only have 5/8 holes. So if I purchased a Freud blade and had it bored out would it upset the integrity or safety on the table saw. I emailed Freud 10 days ago about this question but until now I've had no answer.



Thanks you in adavance.
