Metal Cutting Solutions: Matching Blade Types to Metal Fabrication Tasks
From slitting to shearing: an overview of metal cutting blades — circular slitter blades, shear blades, separator discs and press brake tooling.
Metal fabrication uses a small family of blade types, each matched to a machine and a task. Knowing which family a job belongs to is the first step to buying tooling that lasts.
Slitting: Circular Slitter Blades
Slitter knives cut coil or sheet into strips, working in pairs with spacers and separators. Slit quality depends on the whole set, not just the knife. See our circular metal slitter blades guide for tolerances and steels.
Shearing: Guillotine and Shear Blades
Shear blades cut plate and sheet in a straight line with a rake angle. Steel selection and rake determine edge life and cut distortion. Our metal shear blades and guillotine article covers grades from D2 to HSS.
Bending: Press Brake Tooling
Strictly forming rather than cutting, press brake punches and dies still share the same tool-steel discipline. A primer is available in press brake tooling.
Supporting Parts
Slitting lines also run spacers, rubber bonded rings and separator discs. These wear parts decide how long the expensive knives last, so plan them together as a set.
Why Choose zhongjian
zhongjian (ZHONGJIAN TECH) manufactures the complete metal cutting tooling family in one factory, so hardness, flatness and finish standards stay consistent across knife types. OEM drawings and samples are welcome.
