The 6519-31 is more than capable of performing this demanding application. In order to get maximum blade life, it is recommended that a slower cut speed is used. The 6519-31 has a variable speed trigger, which provides the ability to control cut speed; however,
if this application is performed regularly, it is recommended that a SAWZALL with a variable speed dial is used, such as the 6538-21. The 6538-21 will provide best performance & best blade life in this tough application.
