Tool Holders

Materials for tool holders play a critical role in ensuring dimensional stability, wear resistance, machining performance, and overall tool life. The selection of suitable material depends on factors such as mechanical loading, production volume, required precision, wear conditions, corrosion exposure, and manufacturing costs. Prehardened steels are commonly used for tool holders.

For cutting tools like milling cutters and drill bodies, the tool holder plays a critical role in ensuring rigidity, stability, runout control, and vibration reduction. Tool holder materials for cutting tools must provide a good balance of machinability, sufficient strength, dimensional stability.

• Tool holders for cold work carry dies, punches, forming and blanking tool inserts and operate at relatively low temperatures but are subjected to high mechanical stress and wear.
• Hot work applications place additional demands on tool holder materials due to exposure to heat, thermal fatigue, and temperature fluctuations.
• Tool holders for plastic injection moulding focus on properties like dimensional accuracy, surface finish quality, corrosion resistance and thermal conductivity.
