The Widin Carbide Drill Single Margin Internal Coolant 8XD TiAlN Coated — 6.5 mm diameter is a high-performance drill bit designed for deep-hole drilling. Built from solid carbide, it delivers exceptional rigidity and long tool life, making it a reliable choice for professionals and serious hobbyists who demand consistent results.

With TiAlN coating for wear and heat resistance and a single-margin geometry that maintains stability, this drill stays on target in demanding materials. Its internal coolant and 8xD length enable efficient chip evacuation and accurate holes from start to finish.

• Solid carbide construction: Delivers rigidity and wear resistance for longer tool life and consistent hole quality, even in tough metals.
• TiAlN coating for heat and wear resistance: Reduces edge wear and allows higher cutting speeds without sacrificing life, helping you finish jobs faster.
• Internal coolant with single-margin stability and 8xD depth: Efficient chip evacuation and cooling keep temperatures down, while the single-margin design reduces drift for straight, accurate holes at depth.

Whether you’re machining steel, aluminum, or other tough materials, this drill delivers dependable results from first hole to last. The robust carbide core, protective TiAlN coating, internal cooling, and deep-hole reach work together to reduce heat buildup, minimize chatter, and extend tool life — helping you complete jobs faster with consistent, precise holes.
