spent mandrel into a bottle, creating a cleaner, safer work environment by
preventing spent mandrels from falling to the floor. A traction pulling power
of 2,000 lbs. allows this tool to easily install 3/32” to 3/16” diameter rivets
in all alloys, and ¼” diameter open-end rivets in aluminum/steel
combination. A swivel air inlet along with a push button trigger and molded
frame which provides the operator with maximum comfort using minimal
effort.
The recommended airline pressure is 85-95 PSI.
