® Tiny Tools CMR General Recommendations Coolant fluid Dry machining should not be performed under any circumstances. It is necessary to use an internal coolant in all applications. Oil or Emulsion lubricants are recommended for best performance. In the event of low coolant pressure, adding an external coolant can improve the tool operation. The cooling stream is designed to provide three benefits: 1. Cooling the cutting edge of the tool, and the contact area. 2. Pushing the chip away from the tool quickly, thereby reducing wear of the edge. 3. Helping to break the chip into smaller pieces and evacuating them from the cutting area.
