I’m sure Eric will chime in but it actually is strong enough. I used it to cut the holes for my Aerocatch latches. Keep in mind that was a smaller job size wise. Blade/wheel is key but I kept having to recharge mine. RL template is two rectangles so it’s possible to use it.Clearly this hobby tool is not large enough or strong enough.
And I wonder if this will do the job, maybe better than standard angle grinder because this will have a narrow blade and thus not remove as much material.
I watched a YT video of a mustang owner use the Milwaukee version of the saw to install his Trackspec vents. Both will work
