Note on cutting fluid d : Stocked items
• Cutting fluid should be sufficiently supplied to the drill point and the entrance of the hole.
• Use a water soluble cutting fluid containing relatively high content of extreme pressure additive for heavy duty cutting or use a water-insoluble cutting fluid.
