Widin Carbide Drill Through Coolant 3xD AlTiN Coated - 15.8mm is a rugged carbide drill engineered for reliable through-coolant drilling. Its solid carbide core and through-coolant design deliver consistent performance, efficient chip evacuation, and effective cooling, making it a dependable choice for engineers, machinists, tradespeople, and serious hobbyists tackling demanding metalwork.

• Through-coolant design for efficient cooling and chip evacuation: Directs coolant through the drill to control heat, prevent built-up edge, and clear chips, helping you maintain hole quality and reduce downtime.
• Durable carbide core with AlTiN coating: Combines a tough carbide body with an AlTiN coating for high hardness, excellent wear resistance, and low friction, extending tool life across challenging materials.
• 3xD length for versatile depth coverage: Provides deeper hole capability with maintained stiffness and stability, enabling accurate drilling in thicker workpieces without deflection.

This 15.8 mm diameter drill is built to deliver consistent, precise results from start to finish. The combination of through-coolant capability, a robust carbide core, and a hard-wearing AlTiN coating helps maintain dimensional accuracy, reduce tool wear, and speed up workflows in metal fabrication, automotive, and general machining applications. A reliable, long-lasting choice for shops that demand repeatable performance and minimal rework.
