The Widin Carbide Drill Through Coolant 3xD AlTiN Coated — 17.1 mm diameter — is a solid carbide drill designed for through-coolant applications. Built for durability and long tool life, it delivers consistent drilling performance in demanding metalworking tasks.

This drill is suitable for engineers, machinists, and hobbyists who need reliable depth control and efficient cooling. The 3xD length supports a range of hole depths, while the AlTiN coating offers wear resistance and low friction to help maximize tool life and productivity.

• Solid carbide core for durability: Long tool life and consistent performance in tough metals, reducing tool changes and downtime.
• AlTiN coating for wear resistance: Provides high hardness and low friction, reducing wear and extending tool life even in hard or abrasive materials.
• Through-coolant and 3xD length for versatility: Efficient chip evacuation and cooling for deep holes, minimizing heat buildup and preserving dimensional accuracy.

Together, these features translate into a drill that delivers reliable, repeatable results with less downtime. The through-coolant design keeps temperatures in check, helping maintain accuracy, while the 3xD length gives you depth flexibility without compromising stability. This makes it a dependable choice for production runs, maintenance tasks, and precision projects alike.
