The main functions of a cutting oil are to lubricate or reduce friction between the tool and the work piece, and to act as a coolant by rapidly removing heat generated at the tool-work piece interface.
Soluble cutting oils are mixed with water in proportions of 3 to10%. They are used where rapid heat removal is a major requirement. Usually formulated with emulsifiers, rust inhibitors, and EP additives.
Insoluble cutting oils are used in operations involving tough cutting such as tapping, threading, and broaching. Lubricity and anti-weld characteristics are important characteristics of this cutting oil.

These oils are formulated to lubricate saw chains, and should provide the following benefits:
=
An unbroken film of lubricant between chain links and bars.
= Anti-wear characteristics to prevent chain and bar wear.
= Chain oil should have throw-off resistance. Classified as "tacky".
= Prevent corrosion of the chain.
Tip! The winter grade may be used as an air filter coating where a tacky product is required for dust removal.

A lubricant used as a heat transfer medium in applications such as:
= Plastic extrusion machines.
= Textile dryers.
= Die casting. Some high quality heat transfer fluids can provide clean, odorless operation up to temperatures of 326°C. Petro Canada has a product named CALFLO which is a unique semi-synthetic heat transfer fluid.

Hydraulic systems provide a means to transfer power where gears are impractical. A typical system includes a reservoir for the hydraulic fluid, a pump, transfer hoses, and return hoses to the reservoir.
The important characteristics of a hydraulic fluid are:
=
Thermal stability
= Corrosion protection
= Anti-wear properties
= Anti-foaming properties The oil is available in different viscosity grades to accommodate a variety of ambient operating temperatures.
