   More important than model etc, is type of drill. For holes this size in aged concrete I strongly recommend a SDS Plus or Max drill - the improvement over a hammerdrill is hard to believe.

   I just rented a Milwauke 1/2" Magnum hammer drill for some AB locations I missed. The concrete was 4 days old and the bit went into the concrete like it was butter. I tried it on some old concrete and it still drilled about 1" deep in 30sec.

   *If you're just doing your own house, rent a drill.You can rent a good one for $50/day or buy the same for $500.00.A $200.00 hammer drill sounds like alot of hard work.

   *The Bosch is a rotary hammer SDS drill. Another option would be the Milwaukee model 5368-6 3/4" rotary SDS drill at about $250. Decisions, decisions, decisions...Jerry

   Bosch 11224 is a very good choice for projects around the house. With an optional chuck (about $30), you could drill anything you can find as a DIY. You can even use it to drive screws. With a right angle attachment, you may start thinking about building a new house.

   Of course, you may already have a Milwaukee RAD, 12v, 18v, 24v drills and drivers, then I would suggest you buy the latest and the newest Bosch 2" SDS Max, only about $1,000. It should be big enough. Have fun.

   *If you're considering renting two days of rental will probably buy you a drill at eBay. All of these SDS drills are industrial tools and hard to wear out, a used tool -which a rental is - still have alot of life left. When done with the tool, if your interest is only short term, sell it back on eBay. Really you can't go wrong, as for best choice, buying retail gives you the opportunity to see how each feels in your hand.

   *I think it all depends on how your going to use it. I am a DIY'er.I needed to drills some hole for some red heads to install my patio cover post. The milwakie I dont remember the actual model number is running about 188 bucks appox 212 bucks after taxes(here in orange county calif)so if your a DIY type person like myself. Thats the one I got. Its not a SDS. Its a regular jacobs chuck so I can use it as a heavy duty drill also. Good luck. I guess its like trying to figure which is better Pepsi or Coke.

   *Ron,Pepsi.No one mentioned the difference between hammer drills and rotary hammers. They work differently and require different bits. Rotary hammers are far superior in their performance, bits cost more but last longer. They operate at a slower RPM, but hammer with every revolution.A hammer drill doesn't pound with each revolution, and they tend to burn out bits.

   *I have had that model of Bosch in my truck for years. We drill up to 1" holes but usually 1/2". Never a problem. I'm sure you could spend a ton more $$$ but I have never seen the need for it.

   *Another vote for the Bosch SDS, great little drill. Much better and quieter than any regular hammer drill I've used.Chuck

   *I used a Bosch the other day. I'm not sure of the model number, but know it retails for $600-700. I was going though a basement wall of a 300 year old house (very thick, Big rocks & a course of cinder block). I couldn't have been more impressed with this thing.I've never been disapointed w/ and Bosch tools I've used

   *And get the hammer drill, to churn the Coke into some really big belches.Anybody have a neat trick to retrieve a bit seized against re-bar?

   *nathan,There has been a thread or two on seized bits in concrete. I wonder...if you applied dry ice to the part of the bit still showing if you could get it to shrink enough to come out. Someone talked about how useful dry ice was at the Fest.Rich Beckman

   Any recommendations for a hammer drill (brand, model no.) in the $200 price range for drilling anchor bolt holes in concrete. The hole diameter will not exceed 3/4". Tool Crib offers the Bosch 11224VSR for $209.99 which after a $25 special discount will end up costing $184.99. Seems like a very good price. Does anyone have experience with this unit? I want to do some seismic retrofitting on my house. Thanks ahead of time for any information on this subject.

   This particular drill has provided nothing but problems for my staff and myself. Three repairs later and the chuck still vibrates itself loose after repetitive use when drilling mild concrete. I've sinced swithched to the Makita line and have had no complaints for almost 15 months.
