This 12" manual plate shear is designed for precise cutting of sheet materials in workshops and job-site applications. It uses heat-treated T10 steel blades and a solid Q235 steel frame for strength, stability, and clean results. The shear handles aluminum, steel, copper, plastic, PCB boards, and other thin materials with a maximum cutting thickness of 0.08". A precision blade gap helps reduce burrs, while the extended handle lowers cutting effort during repeated use.
