This tip worked great for my application, be sure to let the tool do its job, no pressure is required or the tip cannot move back and forth. work almost without pressure, if necessary at a 45-degree angle, on hard-to-reach places from the opposite direction. Don't start work that you won't have time to finish. Plan ahead so you don't rush things. I didn't end up breaking a single tile, this tool offers precision, it's a lot easier than by hand and safer than using the multi-tool for narrow gaps
