i have a big intall comming up and i have to use a bunch of 3/4 threaded rod so i have to drill for 1 1/4" anchors. i have tp ick up a new hammer drill that fits the sds max bits. i wish they made a press atachment for the drill for drilling it to cellings. nothing sucks more the drilling in the celling. actually i won't do it anymore but i feel bad for the guys.
What the heck are you hanging with 3/4 ATR. Buy a HILTI hammer drill you wont be sorry!
