TC685 Supreme Thread Milling Cutter for Core Hole and Thread in One Operation

The TC685 Supreme orbital drill/thread milling cutter reduces hard machining times by producing the core hole, the chamfer, and thread in one operation. The cutter’s face milling geometry is specifically 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 2 x DN and 2.5 x DN.

Areas of use include mold & die making and general mechanical engineering, among others. The tool can be used for machining a range of metric thread sizes from M2 to M20.

The cutter is a left-hand cutting tool that features a 15-deg. helix angle for chip removal. Cooling with compressed air helps 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.

Potential benefits include maximum process reliability, a very low cost per thread, and a reduction in the number of tool positions that are required. The new geometry and post-treatment process reduce torque requirements and extend tool life. The TC685 Supreme orbital drill/thread milling cutter is a cost-effective solution even for small and medium batch sizes.
