GSX MILL 4 Flute Endmills Anti-vibration Type GSXVL 4000-2.5D Type

Recommended Cutting Conditions 1. For stable machining performance use rigid, high-precision machines and holders. 2. Use air blow when dry machining. 3. Use wet machining for stainless steel, heat-resistant alloy, and titanium alloy applications. 4. If the machine cannot achieve the recommended spindle speed, please use the maximum spindle speed available.
