How to sell a trademark?

Can I place a phrase on t-shirts to sell under my brand if the phrase is a trademark of another company in an unrelated class of goods?

• I’m starting a t-shirt business and I came up with a catchy phrase (made of 5 really common words) I would like to put on a t-shirt to sell under my brand name. Unfortunately I found that the catchy phrase is a registered trademark in an unrelated field (a company that makes industrial machinery has it trademarked). In addition, I found that the phrase I want to place on a t-shirt has been registered as a domain name by someone unrelated to the industrial machinery company; however the domain name is not currently being used and nothing comes up when I type in the URL. My question is whether I can place this trademarked name (made of 5 really common words) on a t-shirt under my brand name. I understand that I would be infringing on the rights of the company that makes industrial machinery if I attempted to use the phrase as my company name in the same field or class of goods but I’m not sure if that is true in this particular situation since I’m in a different field and have a different company name. To be clear, I have my own company name for which I have filed a trademark application as well as my own domain name for my website which is my companyname.com. My company name is different from the catchy phrase I want to place on t-shirts. Thanks in advance.
