I bought the 18v Milwaukee 1 1/8" rotary hammer, couple SDS drills, and chisels. Now there are jobs where I won't need to drag my 30 some year old Hilti TE-72 along. A couple months ago I bought the Milwaukee 18v 15 ga brad nailer...used the the day it came to reinstall mahogany stops at a skating rink where we replaced all the 4' x 5' insulated units. Won't need my Senco and hose as much.
