Shearing, Cutting, Burrs

Plain sheet metals such as Stainless Steel, Brass, Bronze and Copper should only be cut with a shear. Such a cut will result in a minimal burr on the underside (the unfinished side) of the sheet, while “drawing” the cut on the finished side into very slight rounded edge: the “down-cut” edge. Thin gauge aluminum and metal laminates are generally cut by metal saws and hand tools. Deburring is done with routers and files.
