The Widin Carbide Drill with Internal Coolant is a precision drilling tool designed for metalworking professionals and serious hobbyists who need reliable performance in deep holes. Crafted from solid carbide and finished with a TiAlN coating, it delivers long tool life, enhanced wear resistance, and the heat tolerance needed for higher cutting speeds.

Its single margin design provides superior stability and reduces deviation during drilling, while the internal coolant channel promotes efficient chip evacuation and cooling at the drill tip. With an 8xD length, this drill is well-suited for deeper holes, and the 4.1 mm diameter fits a range of common hole sizes for versatile use.

• Durable Solid Carbide Construction: Built for long tool life and consistent hole quality even in demanding materials, reducing the need for frequent tool changes.
• TiAlN Coating for Wear and Heat Resistance: Enables higher cutting speeds with improved wear resistance, helping maintain accuracy over extended drilling runs.
• Internal Coolant Channel with 8XD Deep-Drill Design: Efficient chip evacuation and targeted cooling minimize heat build-up, supporting deeper, more precise holes with reduced deflection.

Together, these features help you complete deeper holes more reliably, improve workflow efficiency, and achieve repeatable, clean results across a variety of projects. The combination of rugged carbide, protective TiAlN coating, and proactive cooling makes this drill a dependable choice for precision drilling tasks where accuracy and tool life matter.
