Widin Carbide Drills Solid 3xD AlTiN Coated - 7.7mm are professional-grade drill bits designed for precision metalworking. Made from solid carbide, they deliver exceptional hardness and wear resistance for long tool life and consistent performance.

With a 7.7 mm diameter and a 3xD flute length, these bits strike a practical balance between rigidity and versatile drilling depth, making them suitable for a wide range of metals and thicknesses.

• Solid carbide core for long tool life: The ultra-hard carbide body resists wear, maintains sharpness through many holes, and reduces the need for frequent tool changes.
• AlTiN coating for high-heat performance: The advanced coating lowers friction and manages heat, improving chip evacuation and extending cutting edge life in demanding materials.
• 3xD length for rigidity and depth flexibility: The 3xD design provides stable, accurate drilling at deeper depths while preserving clear chip flow and minimizing wandering.

This drill delivers reliable, repeatable results that support faster workflows, fewer reworks, and higher-quality holes across a broad range of commercial and hobbyist applications.
