Widin Carbide Drills Solid 3xD AlTiN Coated - 7.8mm are precision drilling tools built from solid carbide. The carbide core delivers exceptional hardness and long tool life, while the AlTiN coating reduces friction and resists high temperatures, helping you maintain sharpness and consistent hole quality across tough materials. The 3xD length provides a balanced mix of rigidity and versatility for a wide range of drilling depths.

• Solid carbide construction: A robust core delivers long tool life and reliable, repeatable performance across different materials and applications.
• AlTiN coating for heat and wear resistance: Reduces friction, improves chip evacuation, and minimizes wear during high-temperature drilling for cleaner holes and less downtime.
• 3xD length for rigidity and versatility: Provides strong rigidity for accurate drilling at shallow to mid-depths while staying adaptable for a variety of drilling tasks.

This combination of a solid carbide core, high-heat AlTiN coating, and a practical 3xD length helps you complete jobs faster with fewer tool changes, better hole quality, and consistent performance across materials. It’s a dependable choice for engineers, machinists, and hobbyists who value precision and reliability in everyday drilling tasks.
