The Widin Carbide Drill with Internal Coolant is a precision 8.4 mm drill designed for metalworking professionals and serious hobbyists who need deep-hole accuracy. Built from solid carbide and finished with a TiAlN coating, it delivers long tool life, exceptional wear resistance, and improved heat tolerance for faster cutting speeds, while the internal coolant supports chip evacuation and consistent performance over extended use. Its 8xD length design makes deeper holes practical without sacrificing stability.

• Solid carbide construction for durability: Long tool life and dependable performance in demanding metals, reducing replacement frequency and downtime.
• TiAlN coating for wear and heat resistance: Enables higher cutting speeds and longer tool life by resisting wear and dissipating heat during tough cuts.
• Internal coolant with single-margin design for stability: Efficient chip evacuation and cooling, combined with a stable margin geometry that minimizes deviation for precise deep-hole drilling.

Designed to fit into demanding workflows, this drill helps you complete deeper holes with consistent accuracy, cut cycle times, and fewer reworking steps. The combination of internal cooling, robust carbide core, and protective TiAlN coating translates to reliable performance across materials and applications, giving you confidence to push for higher productivity without sacrificing hole quality.
