AE-CPR4-H 4-flute Long Neck Corner Radius Carbide End Mill

The AE-CPR4-H is engineered to achieve high-efficiency milling in high-hardness steels. Its new gash specification with a spiral shape forming from the center to the corner radius improves chip evacuation and prevents chips from getting caught. Chattering is minimized by the AE-CPR4-H’s unequal spacing teeth geometry, enabling highly efficient machining even in deep milling of L/D = 14. With the addition of OSG’s DUROREY coating and smooth surface treatment, surface accuracy is further improved.
