The Widin Carbide Drill Through Coolant 3xD AlTiN Coated - 15.5mm is a solid carbide drill built for through‑coolant machining. It’s designed for professionals and serious hobbyists who need dependable performance, long tool life, and consistent hole quality in metalworking tasks.

With an AlTiN coating for superior wear resistance and a through‑coolant design that promotes efficient cooling and chip evacuation, this drill helps keep cutting edges sharper, reduces heat buildup, and delivers stable, precise holes. The 3xD length provides versatile depth options while maintaining rigidity across a range of drilling applications.

• Solid Carbide Construction: Delivers exceptional rigidity and durability, resisting wear under demanding cutting conditions and reducing tool changes for higher productivity.
• AlTiN Coating for Wear Resistance: A hard, low‑friction coating that minimizes edge wear, supports higher cutting speeds, and extends overall tool life for more holes between changes.
• Through‑Coolant Design with 3xD Stability: Directs coolant to the cutting edge for efficient chip evacuation and cooling, helping maintain dimensional accuracy even on deeper holes and providing versatile depth options with steady performance.

The 15.5mm diameter drill is engineered to deliver reliable, repeatable results across metalworking tasks. By combining through‑coolant efficiency, a durable carbide body, and a protective AlTiN coating, it reduces downtime, improves workflow, and helps you achieve cleaner, more accurate holes with fewer reworks.
