Duracool BR 300 from Enterprise Oil Co. represents an advanced technology in biostable cutting and grinding coolants. Duracool BR 300 is a semisynthetic cutting and grinding fluid with a high oil content for machining all metals from high-alloy stainless steels to aluminum and copper-based alloys.

Duracool BR 300 addresses the problem of multiple coolants in a shop. Duracool BR 300 is unique in that it can be used as a cutting fluid for all machining applications, including severe applications such as aluminum tapping and gundrilling, but can also be used for all water-based grinding applications.

Duracool BR 300 is formulated to be resistant to biological degradation and thus eliminates "Monday morning odors." Duracool BR 300 has high operator acceptance due to its extremely eco-friendly additive package containing no chlorine, sulfur, nitrites, phenolics, heavy metals or dyes, according to the company.

Duracool BR 300 has the lubricity of a soluble oil and the cleanliness of a synthetic. As a result, Duracool BR 300 maintains exceptional cleanliness of both the interior and exterior of a machine tool. Duracool BR 300 has a heavy-duty corrosion package that prevents rusting on all surfaces of the machine including the toolholders. It also gives exceptional rust protection to machined cast iron parts.

Duracool BR 300 will not foam in high-pressure coolant systems even when exceeding 1,000 psi. Duracool BR 300 is 100 percent recyclable, making it environmentally friendly. Duracool BR 300 rejects tramp oils readily so they can be easily skimmed off either in the machine tool or in an exterior recycling system. There should never be a need to dispose of the coolant reducing disposal costs dramatically.
