Cut more, cut faster

Get more tons processed every hour, and put more money in your pocket. Cat shears cut efficiently, and can handle everything from structural steel to cable and sheet scrap. Full rotation gives the operator total control to cut more while moving the machine less.

Tougher than any scrap pile

Built with a structural safety factor almost double of some competitors, your Cat shear will endure wherever your job takes you. Work-hardened steel structures and a solid jaw are just a few of the durability features built in. Plus, the cylinder and hydraulics stay fully protected inside the shear through the entire cutting cycle.

Takes a wrench, not a machine shop

Your Cat shear is designed to make maintenance easy for you. Cutting blades and the piercing tip are all independently replaceable using hand tools. Greasing can be done at ground level - no ladder needed! And all hydraulic systems can be serviced with the shear mounted on the machine - meaning you spend less time servicing, and more time working.

Single-source solution

Only Cat provides you with a scrap-handling SYSTEM: shear, excavator and hydraulics all designed to work together for you. Plus, there's one point of contact for support - your local Cat dealer, part of the world's best dealer network.
