Soluble Oil HD

Heavy-Duty Emulsifiable Metalworking Fluid

Phillips 66®Soluble Oil HD is a chlorinated, heavy-duty metalworking fluid designed to emulsify easily and form a stable emulsion when mixed with water. It provides excellent cooling and lubricity for medium- to heavy-duty cutting and grinding of ferrous and non-ferrous metals, resulting in extended tool life and good surface finishes on the machined parts.

Features & Benefits

• Excellent cooling and lubricating properties

• Excellent anti-wear and anti-weld properties

• Helps extend cutting tool life

• Good surface finish

• Emulsifies easily with water

• Forms a stable emulsion

• Good rust protection

• Good antifoam properties


Soluble Oil HD is recommended for medium- to heavy-duty machining operations with water hardness up to 300 ppm. Typical applications include:

• Broaching • Milling

• Deep hole drilling (gun drilling) • Reaming

• Gear hobbing and gear shaping • Sawing

• Grinding • Tapping
