Widin Carbide Drill Single Margin Internal Coolant 8XD TiAlN Coated - 3.9mm is a precision deep-hole drill built for professionals who demand dependable performance in demanding materials. Designed for engineers, machinists, and workshop teams, it delivers true holes with minimal wandering and exceptional edge durability.

With a solid carbide core and a TiAlN coating, this drill combines outstanding wear resistance with excellent heat tolerance. The internal coolant feature enhances cutting efficiency by promoting fast chip evacuation and keeping the tool and workpiece cooler, which supports higher speeds and longer tool life. The 8xD length provides extra reach for deeper holes while maintaining rigidity and accuracy in a single setup.

• Single Margin Design for Stable Drilling: The dedicated margin geometry delivers enhanced guidance and reduces deviation, helping you maintain straight, true holes even on challenging workpieces.
• Internal Coolant for Efficient Cooling and Chip Evacuation: Built-in coolant channels flood the cut, carry chips away, and prevent heat build-up, resulting in smoother cuts and more consistent hole quality.
• 8XD Length with TiAlN-Coated Carbide for Deep, Durable Holes: Long reach supports deeper drilling in one setup, while the TiAlN coating boosts wear and heat resistance for faster speeds and extended tool life.

This drill helps streamline workflows by delivering reliable, repeatable deep-hole performance with fewer tool changes and less rework. The combination of carbide hardness, TiAlN coating, and internal cooling translates to consistent hole quality, improved surface finishes, and greater overall productivity across a variety of materials.
