Description:MK Diamond's laser welded 404DIP Ductile Iron blade’s unique electroplate coating enables it to dissipate heat – thereby eliminate the rough edge caused by cutting – as well as providing a deburring action that helps to reduce binding during cutting. The deburring action also produces less drag and resistance than any other similar ductile blades. This decreased resistance means faster cutting action and efficiency combined with longer life.
