The Widin Carbide Drill with Internal Coolant is a high-performance drilling tool designed for professionals, engineers, and serious hobbyists who tackle deep-hole tasks. Built from solid carbide and TiAlN-coated, it delivers durable cutting performance and enhanced heat resistance for faster, more reliable results.

With an 8xD length and a single-margin design, this drill delivers stable, accurate holes with minimized deviation, even when drilling deeper. Internal coolant channels actively deliver coolant to the cutting edge and evacuate chips, helping maintain consistent performance and extend tool life. The 12.8 mm diameter provides a strong balance of rigidity and versatility for medium-to-large hole applications.

• Single-margin design for stability: Keeps the drill on course, reduces deviation, and improves hole concentricity in challenging materials.
• Internal coolant and efficient chip evacuation: Delivers coolant directly to the cutting edge, cools the tool, and clears chips to prevent heat buildup and maintain precision.
• 8xD length with TiAlN-coated carbide: Enables deeper-hole drilling with consistent accuracy; TiAlN coating enhances wear resistance and heat tolerance for higher speeds and longer tool life.

This combination of rigidity, cooling, and advanced coating supports faster setup-to-hole completion, cleaner finishes, and reliable performance across a range of materials. It helps you reduce rework, maintain tight tolerances, and maximize productivity in every deep-hole drilling task.
