Air-Powered Squeeze Tools for Solid Rivets

Powered by compressed air, these tools install rivets with nearly double the force of manual rivet tools. Since they squeeze rivets from both sides, they’re also easier to use than air hammers—no need to line up a setter and bucking bar.

Alligator Jaw—1 1/2" Throat Depth


93970A210	93970A101

93970A310	93970A102

Alligator-style tools have two pivoting jaws that meet in the center. They can install rivets at any angle, but they can be harder to position than tools with C-style jaws.

Bench-Mount Air-Powered Squeeze Tools for Solid Rivets

With a bench or cart to keep them steady, these tools install solid rivets along edges more consistently than portable squeeze tools. They close with the press of a foot pedal, so you can use both hands to feed a workpiece through the jaws. These tools are also known as alligator squeezers.

A die set (sold separately) is required and must be attached to the tool jaws to properly form rivets during installation. Choose a die set that matches the rivet's head style.
