Houghto-Grind 4250

High speed surface grinding of metals requires the combination of cooling and rust protection with a low foaming additive package.  Houghto-Grind 4250 contains the newest synthetic additive technology to give you an economical grinding coolant for use in all vertical spindle rotary grinders.  It may be highly diluted with water and it provides excellent rust protection to highly ground surfaces.  Grinding wheels will remain open and free cutting while a high cleaning action takes away fines to minimize loading.  In-use solutions are clean and will not foam.
