Widin Carbide Drill Single Margin Internal Coolant 8XD TiAlN Coated - 3.8mm is a precision-dedicated drill designed for professionals, engineers, and serious hobbyists who demand reliable deep-hole performance. Its solid carbide core and TiAlN coating deliver long tool life and consistent cutting in demanding materials.

Designed for stability and depth, this drill uses a single-margin geometry for reduced wandering, and an internal coolant system to flush chips and cool the cutting edge, enabling clean holes at depth with an 8xD reach.

• TiAlN-coated solid carbide construction: provides exceptional wear resistance and heat tolerance, enabling higher cutting speeds and longer service life for demanding drilling tasks.
• Internal coolant for efficient cooling and chip evacuation: directs coolant to the cutting edge and clears chips effectively, reducing heat buildup and preserving hole accuracy during extended cycles.
• 8xD length with single-margin geometry for deep, stable drilling: supports drilling deeper holes with tight tolerances while the single-margin design minimizes drift for smoother, more reliable holes.

This drill helps streamline deep-hole work by combining a durable carbide core, a hard-wearing TiAlN coating, proactive cooling, and extended reach. Expect consistent hole quality, reduced tool changes, and improved workflow across repetitive or precision-focused applications.
