I took apart my highschool's shop vac to see the dirtiest filter I have ever seen. Going to order a brand new one and I took the whole thing apart and cleaned it all just waiting for the filter .
Are you looking for a brand new drill or used ? If you think about getting a 1/2 drill I highly recommend this drill I have two of the older versions and they run flawlessly . found this one on eBay usually they cost around $200 ish .
