This tool is also available under the Husky for Home Depot brand. This is by far the best compression tool I've found. This is my second. I put it in about 50 silicone tubes a year, and with the following tips it will be good enough for your commercial use for a $5 tool. I suggest: clean the rubber three-way tip every time you put it down. 100% silicone cannot be removed with solvent, it must be shaved off with a razor blade after it has set somewhat. That's why I'm giving up my first instrument. Here's another tip to extend the life of your stainless steel grout remover: My first one broke after about 5 bathrooms (here's a hotel staff). It's barely screwed on from the Chinese factory but works very well. My new one has a continuous ring of JB Steel Stick Epoxy around the pivot and I think this will make it a lot less prone to cracking. See photo of my modification. Enjoy!
