Orbital drill/thread mill machines the core hole and thread in one operation

Walter has introduced the TC685 Supreme orbital drill/thread milling cutter, which produces the core hole, the chamfer, and thread in one operation.

The cutter’s face milling geometry is designed for core hole creation and chamfering. After chamfering to start a hole in the workpiece material, the tool creates the core hole and thread using helical interpolation.

Applications include blind-hole and through-hole threads in steel and hardened steel from 44 to 65 HRC (ISO P and H material groups). The tool is designed for producing thread depths of 2xDN and 2.5xDN. The tool is suitable for machining a range of metric thread sizes from M2 to M20.

The cutter is a left-hand cutting tool that features a 15-degree helix angle. Cooling with compressed air makes it possible to achieve maximum tool life in materials harder than 50 HRC. Additionally, internal coolant delivery is available for tools that create the M6 size through the larger thread sizes. The tool shank is in accordance with the DIN 6535 HA standard.
