Does the moen 137401 replacement tool fit the moen 66100rb faucet?

Yes it does. This part (Moen 137401 is the 1.5gpm version, while Moen 180158 is the 1.2gpm version (just has a smaller flow restrictor). This information is clearly shown if you search for "Moen 6610 Parts". By the way, your part number is not 66100rb, it's 6610orb, the last three letters just mean oil rubbed bronze. The aerator doesn't change for a bronze, nickel or chrome faucet.

Does this work with any Moen faucet. I just bought a 2 year old house. The bathroom faucet is clogged

No, it does not. I had to try every different aerator key at the big stores until I finally found the model of my Moen faucet. There are different sizes.

Which swivel adapter can fit Moen 6410 model?

Hello and thank you for your interest in Moen products. Moen does not manufacture a swivel aerator for the 6410 faucet with an internal aerator. Our products have not been tested for use with external accessories, therefore, we cannot confirm if an adapter will fit. The 137401 aerator has a thread size of M18.5 x l-6G. Should you have additional questions, please feel free to call us at 800-289-6636. We are available Monday through Friday from 8:00 am - 7:00 pm (EST).
