Premium oils for superior lubrication of air operated rock-drilling equipment

Basic Identifiers

ID Type BO
6529 pneumatic mineral


Shell TorculaŽ Oils are specially developed lubricants of high film-strength that provide improved lubrication of rock drills, jackhammers, sinkers and other air operated percussion tools. Shell Torcula Oils are blended with an unusual combination of high film-strength, oiliness and anti-wear additives into high quality mineral oils. These products have consistently provided outstanding field performance. Shell Torcula Oils atomize readily in air line lubricators to make an oil mist. This mist passes through the drill, lubricates the closely-fitted working parts and restricts the build-up of frictional heat. A protective oil film helps prevent metal parts from rust caused by moisture-laden air.

ASTM D341 Viscosity Calculator

You may calculate the viscosity of the oil at various temperatures based on ASTM D341. This uses the two sets of calibration data that we already have in order to calculate the viscosity at any temperature. You may input multiple temperatures at once, seperated by comma.
