Product Details

1.Outer diameter:between 28-610mm (can be customized according to customer requirements) 2.Thickness:0.3-80mm (can be customized according to customer requirements) 3.Material:high carbon steel,high speed steel,tool steel,alloy steel,stainless steel,65MN,9CRSI,CR12MOV,SKD-11,SKH-51,3CR13,9CR18,SUS440C,420J2,W6MO5CR4V2 and many more materials. 4.Cutting edge: small cutting edge single layer :This is more commonly used at present.It is mainly used for cutting relatively hard or relatively thick materials.Such as:self-adhesive,paper,leather,plasitc,etc. large cutting edge double layer:This because the knife edge bevel is relatively large,so the cutting resistance is smaller ,the incision is more flat ,no burrs.Mainly used for cutting relatively high requirements,relatively thin materials,such as:film,thin plasitc,and so on.
