I am trying to remove my kitchen sink. The problem is that there is a clamp in the fromt and one in the back. Usually you can just unscrew these but this is not the case. It looks like they tips have been clipped off or that it was screwed in magically from the top of the sink. It is a stainless steel sink
How am I going to get these clamps off to install my new sink?
What is the sink made from?
Can you break the clamp away ?

If you want to save the sink, breaking off the clamp could very well dent the sink badly. Grinding it away may be in order.
Most sink clips are either formed hardened sheet metal or aluminum. Either can be ground away but I first try to twist the 90 degrees, which will usually cause them to release their grip or at least loosen enough to work the sink out. They may bend, pop loose, of deform that one spot in the mounting rail but unless you use lots of pressure there's little danger to the face side of the sink. In tight spots you may have to get inventive with tooling; try a long open-end wrench with a screwdriver on your end to apply the twisting force. I've only seen a few times this method didn't work.
