The Widin Carbide Drills Solid 3xD AlTiN Coated - 9.9mm is a solid carbide drill built for demanding metalworking tasks. Its 3xD length and AlTiN coating deliver long tool life, reliable performance, and versatile drilling depth options for professional shops and serious hobbyists alike.

• Solid carbide construction: Dense, wear‑resistant core that maintains sharpness for more holes, supporting consistent hole quality and fewer tool changes.
• AlTiN coating for heat resistance: Reduces friction and withstands higher cutting temperatures, helping chips evacuate smoothly and lowering tool wear in demanding drilling conditions.
• 3xD length design: Balances rigidity with reach, enabling stable, accurate drilling across a wide range of depths without sacrificing versatility.

Together, these design choices translate to real‑world value: dependable performance from first hole to last, improved productivity with fewer interruptions for tool swaps, and consistent hole dimensions that reduce rework. The robust carbide core and optimized coating help you tackle thicker workpieces and tougher materials while maintaining clean cuts and predictable results.
