Straight boring knife 20x20 for steel
Professional turning tool straight boring knife according to ISO 8, DIN 4973, size 20x20, NNWa type. This is a high quality straight boring knife with S20/P20 carbide brazed insert. It is a grade designed for machining materials that give a long chip, mainly for hard steel, cast steel and malleable iron. The straight boring lathe knives we offer are suitable for fine and medium precision machining at sufficiently high cutting speeds and moderate feeds. These unique turning knives are dedicated to both individual customers and large locksmith workshops. The biggest advantage of the knives is their high resistance to very difficult cutting conditions. The content of carbides makes the knives resistant to abrasion under high temperatures, as well as resistant to any mechanical damage. In addition, the carbides are characterized by high hardness, increasing the durability of the knives.
