Widin Carbide Drill Through Coolant, 11.1 mm diameter, combines a solid carbide body with an AlTiN coating to deliver long tool life and reliable performance in demanding drilling tasks. The through-coolant design channels coolant directly to the cutting edge, improving chip evacuation and cooling for cleaner holes and extended tool life. With a 3xD length, it offers versatility for various hole depths while maintaining stability and precision.

Whether you’re a professional machinist, maintenance technician, or DIY enthusiast, this drill is built to deliver dependable, repeatable results. The carbide core provides rigid cutting performance, the AlTiN coating enhances wear resistance and reduces friction, and the through-coolant flow helps control heat—together delivering longer life and consistent hole quality across tough materials.

• Through-Coolant Design: Efficient chip evacuation and effective cooling during drilling to minimize heat build-up and extend tool life.
• Carbide Core with AlTiN Coating: Hardened, wear-resistant surface with low friction for longer tool life and more consistent cutting in demanding materials.
• 3xD Length for Versatility: Enables drilling a range of hole depths while preserving stability and precision.

This combination of durability, reliability, and practical through-coolant performance helps you finish jobs faster, reduce tool changes, and achieve accurate hole sizing with every cut.
