Special Application Notes:
- For safety and success, always pre-drill the hole with a pilot drill. This is especially true for drilling small sizes less than .078" [2mm].
- Minimum coolant pressure = 800psi (5.5 MPa).
- Coolant must have Extreme pressure (EP) Additives.
- Positive displacement type coolant pump is required.
- Coolant filter must be less than 5 microns. Fine filtration is necessary to prevent blockage of the Oil Holes.
