Widin Carbide Drills Solid 3xD AlTiN Coated – 6.7mm are precision drill bits made from solid carbide, engineered for dependable performance across demanding metals and deeper drilling tasks. With a 6.7 mm diameter and a 3xD flute length, these bits deliver steady rigidity and versatile reach for professionals, technicians, and serious hobbyists who value consistent hole quality and long tool life.

The AlTiN coating enhances heat resistance and reduces friction, helping cutting edges stay cooler, improving chip evacuation, and minimizing wear during extended use. This means more efficient drilling with fewer stops for tool changes and less chance of galling or built‑up edge issues.

• Solid carbide construction: Delivers exceptional hardness and wear resistance for consistent hole quality and longer tool life in a range of materials.
• AlTiN coating for heat resistance: Reduces friction and enhances chip evacuation, helping edges stay sharp and extend tool life under high temperatures.
• 3xD length for rigidity and depth versatility: Balances stiffness with reach, enabling clean, accurate holes at multiple drilling depths without deflection.

Designed to boost your workflow, these 6.7 mm drills provide reliable, repeatable results from the first hole to the last. The combination of solid carbide, heat‑resistant coating, and the 3xD length helps you complete projects faster, with fewer tool changes and less rework, whether you’re in a professional shop or tackling home workshop tasks.
