Rivet busters from Chicago Pneumatic are designed for concrete breaking and metal cutting. CP 4608 and CP 4611 have 8-inch and 11-inch tool strokes, respectively, and require 45 cfm of air to operate. Controlled Power System (CPS) prevents blank firing when a unit’s rubber bumper is 75 percent worn, which extends equipment life and avoids unexpected downtime, the company says. When the bumper is worn, the outward movement of the upper and lower sleeves opens bleeding ports for air, causing the piston to stop in its lower position. An indicator groove on the lower sleeve shows when its bumbers should be replaced.
