Widin Carbide Drill with Internal Coolant is a robust, precision-focused tool designed for metalworking and fabrication environments. With an 8.7 mm diameter and an 8xD length, it’s built to drill deep, true holes in challenging materials while delivering dependable tool life. The solid carbide construction and TiAlN coating make it a reliable choice for engineers, machinists, and hobbyists alike.

Engineered for performance, the TiAlN coating provides exceptional wear and heat resistance, enabling higher cutting speeds without sacrificing edge life. The single margin geometry delivers stable, straight drilling and minimizes wandering, even when drilling hard metals. An internal coolant channel ensures efficient chip evacuation and effective cooling at the cutting edge, helping maintain consistent results and reduce heat build-up during extended runs.

• Internal coolant for cooling and chip evacuation: Delivers coolant directly to the cutting edge and flushes chips away, minimizing heat buildup and preserving edge life for consistent hole quality.
• Single margin design for stability: Provides improved guidance and less wandering, helping you maintain straight, true holes even in tough materials.
• 8XD length for deep-hole accuracy: 8xD overall length enables deeper hole drilling while preserving rigidity and precision in demanding applications.

This drill is designed to help you complete deep-hole projects with confidence—combining durable carbide, wear-resistant coating, and intelligent coolant-assisted performance to deliver reliable results, reduce downtime, and improve overall workflow in professional shops and serious DIY setups alike.
