Gulfcut 91A is low viscosity neat cutting oil, imparting high lubricity and extremely good thermal stability. This product is particularly suitable for operations requiring high precision like honing. Gulfcut 91A has special additives, which give excellent surface finish on machining of hard to machine metals. This also can be used for super-finishing operations using stones in place of tapes. Carefully selected additive technology does not allow sulphur-leaching of the work-piece.
