The Widin Carbide Drills Solid 3xD AlTiN Coated—13.7 mm diameter—are high-performance drill bits designed for metalworking tasks that demand durability and precision. Constructed from solid carbide, they deliver exceptional hardness, long tool life, and consistent hole quality across challenging materials.

These drills feature a tough solid carbide core with an AlTiN coating that provides high heat resistance and reduces friction. This combination improves chip evacuation and minimizes wear, letting you run at productive speeds with greater reliability. The 3xD length design strikes a balance between rigidity and versatility, enabling stable drilling across a wide range of depths.

• Solid carbide construction: Delivers sustained sharpness and wear resistance for consistent hole size and long tool life, even when drilling hard metals.
• AlTiN coating for heat resistance: Reduces friction and dissipates heat, enabling higher speeds with better edge protection and extended tool life.
• 3xD length for rigidity and depth versatility: Provides stable entry and reduced deflection, making it suitable for shallow to deep holes without chatter.

Together, these features translate into faster, more predictable drilling with fewer tool changes. The tool’s durability and heat resistance help maintain hole accuracy under demanding cutting conditions, while the 3xD length delivers reliable performance across a variety of depths. This means less downtime, consistent results, and more efficient workflows for production runs or DIY projects.
