High-performance M35 cobalt high-speed steel round shank point welding drill bits — available in 6 mm and 8 mm. Key benefits Fast, reliable installation: straight round shank with a rounded chamfer for easy seating and stable mounting, which helps speed up tool changes and improve workflow. Longer tool life and consistent cutting: made from M35 cobalt-containing high-speed steel for high hardness, excellent wear resistance, and a sharp cutting head that lasts longer and resists sticking. Better cutting performance: super-spiral flute and optimized chip-removal geometry reduce cutting resistance and clear chips efficiently, improving processing speed and surface quality. Versatile finishing: suitable for direct machining or for fine finishing of heat-treated molds and workpieces. Features Material: M35 cobalt high-speed steel for high hardness and wear resistance. Design: straight shank handle, rounded chamfer for easy installation, and a sharp, welded point for reliable starts. Flute: super-spiral shape with chip removal design to lower cutting forces and prevent clogging. Durability: sharp cutting head and robust construction for extended service life with less tendency to stick. Specifications / Box contents Included: 6 mm and 8 mm round shank point welding drill bits. Intended use: machining levels, grooves, forming surfaces, and separating workpieces. Typical applications Mold and die work: direct machining and fine finishing of molds, including heat-treated mold surfaces. Detail machining: producing levels, grooves, and precise forming surfaces where a sharp, wear-resistant tool is required. Workpiece separation: cleanly separating components during metalworking or fabrication tasks. Practical advantages Reduces downtime with easier installation and efficient chip removal. Maintains cutting performance over longer runs thanks to M35 cobalt HSS and a wear-resistant geometry. Suitable for both roughing and fine machining operations on challenging materials and mold components.
