This Widin Carbide Drill with Through Coolant and AlTiN coating is built for demanding metalworking tasks. Its solid carbide construction and a 7.8 mm diameter deliver durable, reliable performance and long tool life, while the 3xD length design adds versatility and stability for drilling various hole depths with through coolant capability.
- Solid carbide construction: Delivers high durability and long tool life for consistent, reliable performance across demanding materials.
- AlTiN coating for wear resistance: Combines high hardness with low friction to extend tool life and maintain sharpness under tough cutting conditions.
- Through coolant capability with 3xD length design: Ensures efficient chip evacuation and cooling while drilling at different depths, helping maintain dimensional accuracy and stable cutting performance.
Together, these features translate to longer tool life, more predictable hole quality, and reduced downtime. The through coolant design improves heat management and chip removal, protecting the cutting edges, while the 3xD length design provides versatility for a range of drilling depths—all contributing to reliable, repeatable results in professional shops and workshop environments.
