Meet the Widin Carbide Drill Through Coolant—designed for engineers, machinists, and workshop teams who demand dependable drilling performance. This 9.1 mm drill features a solid carbide core for exceptional rigidity and long tool life, an AlTiN coating for wear resistance, and through-coolant capability that improves cooling and chip evacuation. The 3xD length adds depth versatility and stability, making it suitable for a range of hole depths.

• Solid carbide construction: Delivers exceptional rigidity and long tool life for repeatable performance in tough metals.
• AlTiN coating for wear resistance: Provides high hardness and low friction to reduce wear, preserve edge sharpness, and maintain hole quality under heat.
• Through-coolant design with 3xD length: Enables efficient chip evacuation and cooling, minimizes heat build-up, and supports deeper, stable holes without sacrificing accuracy.

Combined, these features translate to faster cycles, reduced tool wear, and consistent hole accuracy across production runs. The through-coolant path and robust coating help you keep temperatures under control, improve surface finish, and extend tool life—so you can complete more work with fewer tool changes and less rework.
