The Riveting Air Hammers have a beehive-type spring retainer. The operator can easily rotate the cutting tool in any direction while the hammer is still in use. The Riveting Air Hammer can be used for panel cutting, removing drum lids, rivet and bolt busting, setting soft iron or aluminum rivets, as well as a variety of other industrial applications. These hammers use standard .401 Parker Taper Shank Chisels. Our patented metering trigger controls 0-3500 blows per minute.
