Abstract: A collar removal tool can be used on the same type power tool that is used to install frangible collar fasteners. The collar removal tool can be an accessory attachment that couples to the power tool. The collar removal tool can be designed to grip the fastener collar via a collet mechanism that is self-tightening using the power tool. The collar may be removed with the tool running in the reverse rotation, which is the same direction of rotation required to tighten the collet on the collar by raising the collet up into a collet holder. After the collar is loosened and removed from the bolt, the tool can be run in the forward direction and the collar mechanism can automatically loosen the collet on the collar. The collar can then be free to fall from the collar removal device.
