End Mills. The Essential Beginners Guide.

The feed rate of the material must be matched to the optimal speed of the end mill. A 50% reduction in operating speed can double the life span of your end mill. Choose the correct flute count for the application - proper chip evacuation is crucial as heated cutters can lead to low-quality cutting (burnt material, burred edging and dull tooling).
