Widin Carbide Drill Single Margin Internal Coolant 8XD TiAlN Coated - 9.4mm is a high‑strength carbide drill designed for precise, deep‑hole work. Its solid carbide construction delivers stiffness and long tool life, making it a reliable choice for professional shops, engineers, and hobbyists alike. The TiAlN coating boosts wear resistance and heat tolerance, enabling higher cutting speeds while maintaining edge life on tough materials.

Its single-margin design provides stability and reduces wander for clean, accurate holes, while the internal coolant channels deliver efficient chip evacuation and cooling. With an 8xD length, you can reach deeper into thicker workpieces with confidence and consistent hole quality.

• Single Margin Design for Stability: The single cutting edge concentrates the load to reduce deflection, helping you drill straighter holes with consistent diameter and a smooth, reliable finish.
• Internal Coolant for Efficient Cooling and Chip Evacuation: Coolant flows through the drill to the tip, keeping the cutting edge cooler and actively flushing chips away to minimize heat build‑up and protect tool life.
• TiAlN-Coated Solid Carbide with 8XD Reach: The TiAlN coating delivers excellent wear resistance at elevated temperatures, while the 8xD length enables deep‑hole drilling with reliable alignment and longer service between sharpenings.

Together, these features deliver faster material removal, deeper hole capability, and repeatable results across demanding applications. The robust carbide core, combined with protective TiAlN coating and efficient internal cooling, helps you maintain high speeds and consistent hole quality with fewer tool changes and less rework.
