Yes. Install takes less than 5 min. It will work with any brand drill or 1/4 impact as long as the base is no wider than I think 3 1/2 inches.
No. The jaws don't open far enough to get through anything thicker than what they spec.
Yes it fits perfect that's what I have it on works great.
We have not tested the DEWALT DWASHRIR with the Ridgid Brand.
I’m sure it will work and in a pinch I would but keep in mind it’s going to dull the blades quickly and most likely be done and need sharping after the one job
Yes I’ve been using the shears with a Ryobi 18v brushless 1/4 in impact driver.
Don't know for sure because the tool arms might not be the same length as 20v drill
Dear Fred,, ignore the rude answer from prev person,, I too have the Ryobi tools,, and yes the listing does state it works on all cordless drills,, but read the reviews about Ryobi,, it does not fit well, it has to do with where it connects on the battery, very sloppy and loose,, you can use it , but may need to modify,, be careful with it though,, look at other options where the shears attach to the rear of the drill, rather than the battery,, sometimes its not worth asking a question when you get a rude clueless answer from an internet TG,, hope this helps
