How well does this work for removing caulk?

I've used it many times to remove grout from showers and tubs.It works GREAT.

What is the total plunge depth? I need to detach silicone from under a granite window sill.

Check this link, There is a scrapper that is 3" long that's for removing or cutting sealant. https://www.amazon.com/Genesis-GAMT613-3-Inch-Tapered-Sealant/dp/B00FJSWFEM/ref=sr_1_6?crid=10Q1SFGON1H6L&dchild=1&keywords=oscillating+multitool+scraper+blades&qid=1607572816&s=hi&sprefix=Oscillating+Multitool+scraper%2Ctools%2C241&sr=1-6

Will this work for removing wall tile?

I assume you are removing ceramic tile. I have this blade and it’s very flexible. I’ve never used it on ceramic tile. So not sure how well it will hold up. It’s good for removing stuff like hard glue from hard surfaces like concrete where you need the flex. My suggestion would be Rockwell’s Carbide Blade # RW8963.2 (.2 means 2pac). They out last many of the hardened steel blades. I don’t know why but they are hard To get. I think mine came directly from Rockwell. What ever you do don’t buy from the rip off seller on Amazon for $60. They retail for a fraction of that. I forget what I’ve paid. They have teeth & are 1 3/8” wide. Hope this helps.

Is it safe to use this blade on my oscillating multi-tool to remove grout from travertine?

It should be but you would still want to be careful and also test it in a hidden area.
