Tool steel milling and turning

Tool steels are characterized by high wear resistance, very good mechanical properties, low thermal expansion and high hardness and toughness. As a material for turning and milling, tool steel is used for a wide variety of applications in tool making (e.g. cutting edges, punches, inserts, molds, etc.).

At Spanflug you can choose from seven different tool steels for CNC machining (milling and turning). Our overview will help you choose the ideal material for your turning and milling parts.

Surface treatments for turning and milling parts made of tool steel

After turning and milling, parts made of tool steel are often subjected to a Heat treatment subjected to. For this purpose, you can choose from the common procedures.

This is how easy it is to order tool steel parts from Spanflug: 

Upload CAD model, select suitable material and post-treatment, call up instant quote and order directly online.
