Brochure List . | . Aluminum Rougher | | Do you have a machining center with Coolant Through the Spindle capabilities? If so, take advantage of Onsrud Cutter's through-coolant roughers.Through coolant provides flow and pressure directly to the cutting zone. The coolant provides lubricant, dissipates heat and clears chips, which is especially important during deep cavity work, resulting in increased tool life and productivity levels. An improved rougher pattern generates lower cutting forces and allows for increased feed rates. |
