Description
The Widin Carbide Drill Through Coolant 3xD AlTiN Coated - 18.5mm is a solid carbide drill designed for durability and precision. Its AlTiN coating reduces wear and friction, while the through-coolant design improves coolant delivery and chip evacuation for tougher materials.
The 3xD length adds depth versatility without sacrificing stability, making it ideal for engineers, machinists, fabricators, and serious hobbyists who need reliable, repeatable holes with minimal tool changes.
- Solid carbide construction for long tool life: A robust carbide core resists wear and maintains a sharp cutting edge, delivering consistent performance over many holes and reducing the need for frequent replacements.
- AlTiN coating for wear resistance and low friction: The hard, low-friction coating extends edge life, enables efficient cutting at higher speeds, and helps maintain hole geometry across demanding applications.
- Through-coolant design with 3xD length: Through-coolant channels improve cooling and chip evacuation, while the 3xD length provides depth flexibility with steady guidance and reduced heat-related distortion.
This drill supports efficient, reliable metalworking workflows by combining durable carbide, a protective AlTiN coating, and through-coolant technology. Expect consistent hole quality, reduced downtime due to tool wear, and versatile depth options that keep your projects moving smoothly from start to finish.
