The high-efficiency thread mill AT-2 R-SPEC is engineered to dramatically reduce machining time in non-ferrous metal applications such as aluminum alloy by its continuous helical cutting ability, which combines drilling and threading into a single process.
Features & Benefits:
- DLC-IGUSS Coating: prevents welding on the cutting edge
- End Cutting Edge: Helical drilling and threading can be done simultaneously
- Unique Cutting Edge Shape: Prevents deflection of tool
- 2-Flute: For wide chip room
