Metalworking Straight Oils
Industry Applications

Straight oils, also sometimes called neat oils, are petroleum-oil or synthetic-oil based and do not contain water. They are generally used for processes that require maximum lubrication with little cooling capability. Lubrication is necessary to reduce friction between the tool and the part, which results in improved tool life and better finishes on the new part. They perform best at slower speeds, high metal-to-metal contact, or with older machines made specifically for use with straight oils.

Straight oils provide excellent corrosion protection for the newly machined parts and machine tools. Tulco has developed a full line of straight oils that cover the multitude of metalworking operations and the different metal types used in these operations. Different additive technologies work best at certain temperatures and with certain metal types. Tulco can help you select the best straight oil for your specific operation with these factors in mind.
