The Widin Carbide Drill Through Coolant 3xD (AlTiN Coated) is a through‑coolant drill designed for reliable performance in demanding metalworking tasks. With a 16.5 mm diameter and a generous 3xD length, it delivers deep, precise holes with stability and consistent results—making it a strong choice for engineers, machinists, tradespeople, and serious hobbyists alike.

Built from solid carbide and finished with an AlTiN coating, this drill foregrounds durability and efficiency. The carbide core stands up to tough metals while maintaining sharpness over many cycles, and the AlTiN coating provides excellent wear resistance, high hardness, and low friction to extend tool life and maintain cutting performance. The through-coolant design enhances cooling and chip evacuation, helping minimize heat buildup and preserve dimensional accuracy even when drilling deeper holes.

• Solid carbide construction for long tool life: Delivers durable, reliable performance and consistent hole quality across tough materials, reducing tool changes and downtime.
• AlTiN coating for wear resistance and low friction: Keeps the cutting edge sharper longer, lowers heat generation, and supports higher performance and productivity.
• Through coolant and 3xD length: Enables efficient cooling and chip removal while offering versatile depth drilling and stable, precise results.

This combination of rugged construction, advanced coating, and through-coolant design helps you complete jobs with fewer interruptions, maintain tight tolerances, and achieve smooth, repeatable results across a range of depths and materials.
