When you read the words "high speed steel" you think durability. Unfortunately not in our case. The first hole I tried to drill broke with the drill bit. It's okay because the drills keep breaking. Now the second drop, the flute flies out, rubbish. Going forward, you'll need to take care of these items to ensure they last. If the last two sinks aren't the last ones, I order more expensive sinks that have worked in the past. Needless to say, the buyer needs to beware.
