Semi Synthetic Oils (Sharp-7000)

Product Description

Sharp 7000 has been developed to supply the modern machine workshop with a single versatile product to cope with a wide range of machining operations. It is soluble oil based on solvent refined mineral oil containing sulphurised and chlorinated EP additives. Sharp 7000 Forms an opaque translucent emulsion. Its excellent lubricity handles slow speed and high pressure operations, while its superior level of Extreme Pressure additives permits the use of high speed CNC machine cutting of tough alloys.

Sharp 7000 possesses first class inhibition to ferrous corrosion and aluminium stain formation. The product readily dilutes in all water qualities to form a fine, low odour, translucent brown emulsion, and resits oil separation and separates tram oils. 


• Very good rust prevention on parts after machining

• High Level of Extreme Presssure Additives

• Excellent Cooling Power

• All metal compatibility - Al, Cu, Zn, Fe, Bronze, Mg etc.

• Extended sump life- 6months - 1 year

• Exceptional Resistance to bacterial degradation

• Adapted for a wide range of machine feeds & speeds

• Fewer nicks & wearability on tools

• Lower Operational temperatures

Coolant Management

Dilution: Do not add just water and then the cutting oil to the tank. Rather make a mixture separately in a barrel for the required concentration and mix throughougly. Then add this mixture to the machine coolant tank. Use a hand refractrometer to constantly measure the concentration and record regularly on the machine.

Tramp Oils arise from positive loss lubricators, oily stock, hydraulics, etc. If allowed to build up in the system, tramp oils are the most frequent cause of performance loss. Their presence leads to bacterial degradation, deemulsification, souring (pH drop) corrosion and poor finishes. On machines standing idle, anaerobic spoilage can be prevented by re-circulating the coolant a few hours twice weekly. Staff will be pleased to provide onsite technical advice and training on your specific coolant requirements.
