The Widin Carbide Drill Through Coolant with AlTiN coating is a precision 6.1 mm diameter drill built for durable, reliable performance. Crafted from solid carbide, it delivers long tool life and consistent results across a range of drilling tasks, making it a trusted choice for engineers, tradespeople, and hobbyists who need dependable holes from the first cut.

Designed for efficiency in real-world machining, this drill features through coolant capability that enhances chip evacuation and cooling. The result is reduced heat buildup and better dimensional stability, so you can drill deeper with confidence and fewer reworks.

• Through coolant delivery for cooling and chip evacuation: Keeps the cutting zone cooler, reduces heat-related wear, and supports accurate hole sizes even on longer drilling tasks.
• AlTiN coating for wear resistance: Increases hardness and lowers friction, extending tool life and preserving cutting performance over many holes.
• 3xD length for depth versatility and stability: Enables drilling of deeper holes while maintaining rigidity and straightness for consistent results.

Together, these features help you complete projects faster with fewer tool changes and less rework. The combination of durable carbide, protective coating, and practical through-coolant design translates to reliable, repeatable hole quality and longer overall tool life.
