what size drill bit would i need to drill my 93's to 120's??
#31, but why??
im not quite up on my machinist tools but a #31 would come out to a what on standard sizes like in 32's
hey man thanks! I think im just gonna drill them out myself i got a nice drill press and my 93's already got the filters knocked out so it would be a walk in the park if i take my time
do the filters ever need replacement?? if they are filters they must eventually get dirty, no?
