Knife-Lock is a high precision carbide moulder knife system for millwork manufactures who cut glue lines, hardwoods, & Medium Density Fiberboards (MDF). The carbide knife locks on to and indexes up on a corrugated High Speed Steel backing support plate as it is re-sharpened. Polished to mirror finish, our C3 Micro Grain carbide knives offer finer material finishes and longer production runs while providing longer diamond grinding wheel wear. The backing plates are a one time purchase, only replacement carbide knives are needed as they are sharpened away. Our carbide knives are also 100% compatible with your existing backing plates. Knives and backing plates are CNC ground on creep feed crush grinders for precise locking, closer balance tolerances from knife to knife, and less initial grinding.
