Description: Drill-Thread Milling Cutters is designed specifically for grey cast iron. This equipment is capable of performing three operation- drilling, counter boring, and thread milling. Thereby it saves at least one tool change and allows thread manufacturing to be carried out in a single operation. The tool reduces the machining time compared to the conventional methods. In standard versions, the BGF drill-thread milling cutters are designed with two flutes and appropriately large chip spaces for drilling into solid. A new 4-flute version is designed especially for use in grey cast iron and allows even shorter cycle times for this. With the same feed per tooth, double feeds can be achieved at thread milling. This reduces the cycle times by up to 30 per cent compared to 2-flute version. In addition, because of the large number of teeth longer tool life is also possible.
