[PROBLEMS] To provide a metalworking lubricant composition excellent in workability of a metal or an alloy thereof, particularly in workability when deep drawing a nonferrous metal such as aluminum or aluminum alloy, and at the same time, generation of metal wear powder and surface damage. The object is to provide a lubricating oil composition for metal working, which can suppress the above and obtain a product having excellent surface quality. A base oil comprising a mineral oil and / or a synthetic oil and having a kinematic viscosity at 40 ° C. of 50 to 300 mm 2 / s and a general formula (I) based on the total amount of the composition. [Wherein, R 1 is an alkyl group, an alkenyl group or an arylalkyl group, R 2 and R 3 are each independently a hydrogen atom or a methyl group, A 1 O and A 2 O are each independently an oxyalkylene group, n Are 0, 1 or 2, p, q are average addition mole numbers, respectively, and p + q shows the number of 0-5. ] The lubricating oil composition for metalworking characterized by including 0.01-10 mass% of glycerol derivatives represented by these.
