Big Bear Rod Grease


Earth Pro Big Bear Rod Grease is specially thickened extreme pressure grease with additives that provide corrosion, wear and oxidation resistance. It is recommended for grease lubrication on diamond drill rods whether operating on the surface or underground.

Tackiness assures adherence to drill rods while providing superior resistance to water washing and centrifugal separation. It possesses the right degree of fibrous characteristics to permit easy smearing of the drill rods by hand.

As the rods are lowered into the drill hole, an adhesive film is formed on the rods that is resistant to the washing action of the water and “sludge” containing rock cuttings.

This film of grease is a durable one that will prevent momentary seizure and chattering of the rods or binding in the hole. The frequency of pulling the rods for greasing is reduced and increased drilling costs are avoided.
