==========High-concerned chemical : None

• Made from solid carbide with a hardness of HRC70, this twist drill bit delivers superior wear resistance and durability for drilling into tough materials like cast iron and aluminum.
• Features an extended 150mm length, providing the necessary reach to create deep holes in thick workpieces while maintaining stability during CNC machine tool operations.
• The precision-ground spiral flute design ensures efficient chip evacuation and reduces heat buildup, preventing clogging and allowing for smooth, continuous drilling performance.
• Available in diameters from 3.0mm to 13.0mm (sold as 1 piece per size), this tool meets diverse requirements for precise hole making in automotive, mold, and general mechanical fabrication.
• Engineered geometry supports high-speed rotation and consistent material removal, resulting in accurate hole dimensions and clean surface finishes on both ferrous and non-ferrous alloys.
