How to Select
Choose neutral, left-hand or right-hand form according to feed direction.
Confirm groove width, shallow-groove depth and available clearance.
Match the insert to the compatible holder system.
Confirm material and cutting stability before selecting the grade.
Grade & Coating Selection
The insert ordering code defines the geometry and dimensions. The coating is selected through the JetEdge grade according to the workpiece material and cutting condition.
