Victory TDX series segment milling tools
1. Tool structure (see Figure 1)
2. Technical specifications for TDX series segment milling tools (see Table 1)
3. Working principle: After starting the pump, the tool piston descends under the pressure difference, and the lower push plate of the piston pushes the blade to open; After stopping the pump, the piston resets under the action of the spring, and the blade automatically retracts.
