How to Select
Select the groove width first: 1.5, 2.0, 2.5, 3.0, 4.0, 5.0 or 6.0 mm as listed.
Match DR, G, M or T to the required geometry and compatible holder.
Confirm parting or grooving operation, work diameter and maximum depth.
Choose grade according to material, overhang, coolant and machine stability.
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.
