Basics

A Power Tool that oscillates a blade at a high frequency
Attatchments similar to a Sanding Block can also be attatched, if the quality of a Random Orbital Sander is not needed
Major use is for cutting Drywall for Outlets (and essentially anything that is not square, for that a Hole Saw / Hole Saw Kit can be used)
Often called "Multitools" as a longer form name that is sometimes used is "Oscillating Multitool"
The Masonry Blades are also of use supposedly quite useful for applications where a SDS Rotary Hammer Drill wouldn't be used
Framing and Masonry Work Seem Pretty Significant Application Wise, i haven't been around any residential/wood stud framers yet, but may ask about that, know nothing and have no contacts masonry wise short of asking my electrical coworkers, see if they did the same tasks in remodel (may have been what they were reffering to with the masonry blades)

Industry Standards

Dewalt and Milwaukee are what i have seen, looking for more deatails now
- Most of the tests/reviews are agreeing, one might have been UK and they mentioned Festool which was suposedly good as well
Now currently getting lost in voltages
- Milwaukee has the M12, M18, and MX (Not Missile lol) Fuel Systems
- Dewalt had a 12v system but are doing away with that
- Otherwise has 18v and 52v System
  - Also a somewhat novel 18v Battery Pack (in the same form factor) consisting of an enclosed stack of Prismatic Pouch Cell Batteries
    - More Amp Hours for the Same Size Pack is the Advantage i think, need to see if/how quick they form "forbidden pillows"

Recipricating Saw (Can be used in similar situations, although it can be less "gentle" and more bulky, single handed options don't have as much of the bulkyness issue)
