Indexable Tools Tooling by DIJET DIJET Mill 90 SSD90TYPE Economical shoulder milling cutter SSD90 uses four cutting edge insert. 1. Combination of M class insert with 3D geometry and high precision body achieves true 90 degree with no mismatch and excellent surface roughness. 2. Adopted carbide shim prevents body damage and improves security in case if insert is broken. SSD90 gives wide application for cast iron, general steel and hardened steel. JC5040 is suitable for general steel, JC605W for cast iron, JC8015 for nodular cast iron and hardened steel and tough grade JC8050 for unfavourable conditions. CUTTING PERFORMANCE 1.
