Melinda and Thomas worked like Trojans to get all the anchor bolts into the concrete. After the disaster of the Hilti drill expiring we went to Bunnings and bought a $130 dollar bargain basement Ozito rotary hammer drill. Ozito make really cheap tools that do what you expect them to do. If you don't use them a lot they last for years. I have had a few Ozito tools over the years and apart from a cheap cordless drill that has a battery life of about 30 seconds they have all been ok. You get what you pay for and if you want something that you are going to be able to go hard with day in day out for years then avoid them but if you want an occasional tool that you only use a couple of times a year they are ok (avoid their cordless stuff though it really is rubbish)
Anyway the Ozito rotary hammer drill is a beast and chewed through the remaining holes like a hot knife through butter.
Still sometimes you want a tool to last 20 years that will take all the abuse you will throw at it and then some. In these cases it pays to spend a bit extra. After using the brother in laws Milwaukee cordless drill I was convinced about the merits of buying a hardcore 18v drill. After some research I contacted my mate Justin at Rudd Industrial. He put me onto a Bosch Destroyer at mates rates (Big thanks Jus). It is an exquisite tool, with lots of metal components (in place of plastic). The torque this thing generates is phenomenal (it nearly broke my wrist when it caught unexpectedly drilling a 10mm hole in a frame). This is very nice tool that I expect to own for a very long time.
