GSX MILL 4 Flute Endmills Sharp Edge GSX 40000S-2D 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 chatter is a problem, reduce the spindle speed and feed rate indicated in the table below by the same ratio, or reduce the depth of cut. 5. This series is not recommended for groove milling. 6. If the machine cannot achieve the recommended spindle speed, please use the maximum spindle speed available.
