The Widin Carbide Drill Through Coolant 3xD AlTiN Coated – 17.8mm is a high-performance solid carbide drill designed for through‑coolant systems. It delivers consistent, reliable cutting and long tool life in demanding metalworking tasks, helping you complete precise holes with fewer tool changes.
Featuring a 17.8 mm diameter and a 3xD length, this drill offers versatile depth capability while maintaining stability and accuracy. The AlTiN coating provides exceptional wear resistance and low friction, while the through‑coolant design promotes efficient chip evacuation and effective cooling to minimize heat build‑up during drilling.
- Solid Carbide Construction: Built for durability and long tool life, delivering dependable performance through tough materials and repeated use.
- AlTiN Coating for Wear Resistance and Low Friction: Elevates hardness and reduces wear, helping maintain sharpness, extend tool life, and support consistent cut quality.
- Through Coolant & 3xD Length Versatility: Through‑coolant channels improve cooling and chip evacuation, while the 3xD length provides depth flexibility without sacrificing stability.
This drill helps you reduce downtime, maintain accurate hole dimensions, and boost overall productivity. With its durable carbide core, protective AlTiN coating, and through‑coolant design, it delivers reliable performance across a range of drilling tasks, from shallow to deeper holes, in demanding materials and production environments.
