SCT’s Sun Hydraulics Rougher is built for aggressive stock removal and consistent performance in cartridge valve cavity machining. Featuring a brazed carbide tip, AlTiN+ coating for high-speed cutting, and coolant holes in each flute, this tool promotes efficient chip evacuation and thermal control. The polished flute face and precision-ground geometry ensure maximum concentricity, making it the ideal choice for preparing Sun cavities prior to finishing.
