North American Tools General Purpose Thread Mills with Coolant Through Designed with the same characteristics as our General Purpose tools, these standard UN Fractional products feature Axial Coolant off the shelf. This feature is important if your machining center only has through the spindle coolant, or if high heat is present in the cut and coolant reduces the temperature and aids with chip evacuation. Bright finish is featured in first column.
