ABSTRACT:
An apparatus to remove a rivet from a chain saw chain. The apparatus includes a body with a recess in the body. A partially threaded opening is formed at one end of the body and extends to the recess. An anvil can be located in the recess. There is a slot in the anvil of predetermined width to contact a saw chain of predetermined pitch. A bolt is received in the partially threaded opening and a punch member is received in the opening. The punch member abuts the bolt to extend to the recess. Thus, tightening of the bolt extends the punch into the recess and the punch can thus be driven to break the head of a rivet in a saw chain. Preferably the apparatus includes a spinner to allow forming of a rivet in a saw chain. The apparatus is easy to use, easy to transport and, in particular, can be used easily on the job site.
