Answer: 
A rotary hammer drill is the tool to use for drilling holes in concrete. Some clarification is needed however. What is the diameter of the hole you need to drill? If you are sinking a sump pump below the level of the floor, a hole the size of a 5 gallon bucket +/- will be necessary. If this is the case, a jackhammer would be a better tool for that job.

Answer: 
It can be done with the smaller roto hammer, but will take a little longer than with the larger one Bosch suggested. However, if you think you may run into re-bar, you could save yourself a headache and hire or rent a core driller.

Answer: 
The Bosch 11255VSR would be too small of a hammer to chip out the floor, you would need a SDS-MAX hammer with more impact energy to do that type of work.

I need a drill to drill 1 inch holes in some very hard rock. Is this drill capable of doing that?

Also, I heard that if I was going to drill holes in rocks, I would most likely need a Max model and bits. Are the SDS & SDS Plus drill bits capable of drilling 12 inch holes in rocks? If they are, are they durable? DO you need to use water on them to keep them from heating up?

Answer: 
Never ever buy a cheap bit for any drilling tool, and the Bosch seem to be as good as they get. If you pay 50% more money and get 100% more work out of one, you've bought well.
If your bits are heating up to the point that you are worrying about them (yep, they can turn red!), the poor drill motor will need a break as well. Pull it out and let it spin freely.

Thank you for your question. The Bosch 11255VSR will drill up to a 1" diameter hole into concrete. You do not need to use water with this rotary hammer. We do offer 1" diameter SDS Plus bits up to 16" usable length and 18" overall length.

They do make 1 " diameter bits for it. I am not sure about your specific rock though as you did not specify. With concrete there would be no problem. To give you an idea how this rotary hammer works. I tried to drill 3/8" holes in some tough concrete with a lot of rocks in it with a regular hand hammer drill. I would take me about 20 minutes for a hole especially when it hit a rock, which would happen Read More

I tried to drill 3/8" holes in some tough concrete with a lot of rocks in it with a regular hand hammer drill. I would take me about 20 minutes for a hole especially when it hit a rock, which would happen 2-3 times per hole.
I broke down and bought this rotary hammer. And was able to finish the job at the rate 20 seconds per hole, rocks did not slow it down at all.
And no you do not use water with this.

I bought this tool specifically to break up large Granite rocks. I just tackled my first one, drilling 20 holes at 5/8" diameter, to a depth of 6", with the holes spaced about 5" apart in a "+" sign pattern across the face of a 4'x3'x1' rock that was far too heavy to lift or move by hand.

I bought this tool specifically to break up large Granite rocks. I just tackled my first one, drilling 20 holes at 5/8" diameter, to a depth of 6", with the holes spaced about 5" apart in a "+" sign pattern across the face of a 4'x3'x1' rock that was far too heavy to lift or move by hand. I chased the drilling with 5/8" feather & wedge pieces, first across one line, and then across the lines in the resulting two pieces, and rock split easily. The only trick is not putting too much pressure on the drill as its doing its work - let the hammer action bounce the bit in the hole, and break up/pulverize the stone as its cutting. Great tool for this sort of work. If I had LOTS of stone to do, I probably would buy something larger, but this rotary hammer drill will do what I need it to for many pent-up projects around here that have been blocked by boulders hiding just below the ground, and sticking up in to the yard in other places.

Rated 5.0 out of 5.0 by Good Investment Easy to assemble and use. Way more capability than I needed but the price made it a good investment over comparable makes/models. Will inspire me to tackle other projects around the farm. May 31, 2016
Rated 5.0 out of 5.0 by Great tool, wish I had gotten it sooner I used this to take down a 40ft chimney. Worked like a charm. Very easy with a good chisel bit in hammer mode. I originally started by trying to take out the mortar by using a 4" grinder. Nope. rotary hammer is THE tool for masonry removal. May 24, 2016
Rated 5.0 out of 5.0 by Great value The rotary hammer is nice and light but has plenty of power. The narrow linear design helps when reaching into tight spaces or deep holes, like post holes. I can always rely on Bosch product quality. May 3, 2016
