This tool is designed to maximize reach without sacrificing rigidity, making it ideal for deep slots and extended pockets. The cobalt-based HSS‑E composition offers enhanced wear resistance when cutting tough steels and copper alloys, helping maintain sharpness and accuracy over longer runs. The two‑flute geometry supports efficient chip evacuation and smooth cutting action, while the 30° helix promotes steady chip flow and reduced cutting forces in shoulder milling. With a 12 mm plain shank, it fits standard machines and collets for dependable compatibility. Whether you’re fabricating enclosures, automotive components, or intricate prototypes, the C122 slot drill delivers consistent performance in demanding long-reach applications.
