Abstract: An improved frac plug apparatus and method for setting a plug in a downhole. In an embodiment, the apparatus comprises an inner cone shaped member having a first end and a second end, the inner cone shaped member having a generally increasing outer diameter from the first end, and an expandable outer sleeve having a first end and a second end, the first end of the expandable outer sleeve adapted to receive the first end of the inner cone shaped member and the second end of the expandable outer sleeve having a plurality of fingers joined at their tips at predetermined break points. In use, upon receiving the first end of the inner cone shaped member further into the expandable outer sleeve, the fingers of the expandable outer sleeve are adapted to break at their tips at their predetermined break points and expand outwardly to engage a surface of the downhole.
