The Widin Carbide Drill with Internal Coolant is a precision cutting tool engineered for deep-hole drilling. With a 4.3 mm diameter and an 8xD length, this drill is ideal for engineers, machinists, and hobbyists who need repeatable, accurate holes with reliable tool life.

Constructed with a solid carbide core and a TiAlN coating, it resists wear and heat, enabling higher cutting speeds and longer life. The single-margin design provides excellent stability and minimizes deviation, while the internal coolant channel improves chip evacuation and cooling for consistent performance.

• Durable solid carbide core: Long tool life and reliable performance across repeated holes, even in demanding drilling tasks.
• TiAlN coating for wear and heat resistance: Reduces wear and allows higher cutting speeds by withstanding elevated temperatures, extending tool life.
• Internal coolant and 8XD depth with single-margin design: Efficient chip evacuation and cooling combined with stable drilling for deep holes with minimal deflection.

This drill helps you complete deep-hole projects more efficiently by combining durability, heat resistance, and stable cutting. The internal coolant reduces heat buildup and chips stay clear, helping you maintain hole straightness and accuracy while cutting faster. With a long 8xD reach and a robust carbide core, you can reduce tool changes and keep production flow steady from start to finish.
