Unlike pop rivets, solid buck rivets must be exactly the right length for the material you are clinching. A rivet cutter is used to cut the bodies of longer aluminum rivets to the proper length for the project you are doing. Simply set the head's adjustable leaves to the desired length and cut as many rivets as you need for the window frame, door frame or whatever you are working on. Our high quality heavy duty cutter is made of durable hardened steel and can easily cut rivets of any standard diameter from 1/16" to 1/4" without burring. The length of the cut rivet can be varied from 1/4" to 3/4" in 1/16" increments.
