RECOMMENDED SPECIFICATIONS FOR ROCK DRILL
LUBRICANT
The use of synthetic oils is NOT RECOMMENDED due to possible damage to seals, “O” rings, hoses, blades, and polycarbonate oiler/filter bowls. Use
only a non-detergent, Class 2, pneumatic lubricating oil (viscosity 100-200 S.S.U. @ 100° F and minimum aniline point of 200°F); which contains no
synthetic additives; and which is compatible with Buna-N, Neoprene, Urethane, Silicone, and Hytrel components.
Consistency shall be such that the oil will adhere readily to metallic surfaces under extreme pressure conditions that exist in a rock drill.
Flash, Cleveland open cup…………………………………………………………..380°F Min. (a)
Carbon Residue………………………………………………………………………0-30% Max.
Viscosity at Atmospheric Temperature
Below 20°F………………………………………………………………… SAE #10
20° to 40°F………………………………………………………………… SAE #20
40° to 80°F………………………………………………………………… SAE #30
80° to 110°F……………………………………………………………….. SAE #40
Above 100°F………………………………………………………………. SAE #50
Mineral Activity……………………………………………………………………… None
Free Fatty Acid (as Oleic %)……………………………………………………… 0.40% Max.
ASTM Steam Emulsion No……………………………………………………….. 600 Max. (b)
Metallic Soaps……………………………………………………………………… None
Pour Point F………………………………………………………………………… +10 Max. (c)
Film Strength PSI
Almen Test……………………………………………………………….. 12,000 (d)
Weeks Test………………………………………………………………. 8,000 (d)
(a) Where lower than normal viscosity oil is used at extreme low temperature, 350°F flash point permissible.
(b) 1200+ desired where moisture is a major factor. Operator must compensate for foaming when filling the lubricator.
(c) For below normal atmospheric temperature operation, lower pour test product may be required.
(d) Desired values, not minimum. Rock drill oils must have appreciably greater load carrying ability than straight mineral oils of like viscosity. High film
strength is required by the heavy rotational loads present in drilling conditions. Additives which impart extreme pressure characteristics to the oil must
be non-corrosive to the drill mechanism.
