Widin Carbide Drills Through Coolant 5xD AlTiN Coated - 14.3mm

These through-coolant carbide drills, 14.3 mm diameter with a 5xD flute length, are built for precision and long-term durability in metalworking. The AlTiN coating reduces wear and enables higher cutting speeds, while the through-coolant design ensures efficient cooling and chip evacuation for deeper holes. Ideal for engineers, machinists, tradespeople, and DIY enthusiasts who require reliable performance on demanding materials.

• Solid carbide core for long tool life: Built from a solid carbide core to resist wear and maintain precise hole sizes, delivering dependable performance over many holes with fewer tool changes.
• AlTiN coating for wear resistance and higher speeds: The AlTiN coating provides enhanced wear resistance and lower friction at the cutting edge, enabling higher cutting speeds without overheating and extending tool life.
• Through-coolant design with 5xD length for deep, stable drilling: Through-coolant channels deliver coolant directly to the tip and improve chip evacuation, while the 5xD length provides rigidity and stability for deeper holes.

With these features, you gain reliable, repeatable hole quality across materials, reduced downtime from fewer tool changes, and the ability to tackle deeper holes in a single setup. The combination of a durable carbide core, wear-resistant coating, and through-coolant technology keeps heat in check and chips moving, so you can maintain higher feeds, longer runs, and consistent results from the first hole to the last.
