Deep-hole Drilling Inserts Description
Deep-hole drilling inserts are universal inserts designed for high productivity in various industrial sectors: Energy, construction machinery, injection moulding, aviation, shipbuilding, national defence, etc. They achieve consistent drill straightness in long workpieces and maintain a high surface finish. The available geometries and grades allow machining of steel, stainless steel and superalloys, etc.
