The Widin Carbide Drill Through Coolant 12.9 mm is a solid carbide drill designed for through-coolant applications. It delivers dependable, consistent hole-making with efficient chip evacuation, making it a reliable choice for engineers, machinists, and DIY enthusiasts seeking reliable performance and long tool life across a range of materials.

• Solid Carbide Construction: Delivers outstanding rigidity and wear resistance, meaning more holes per drill and fewer tool changes, so your production stays on schedule.
• Through-Coolant Capability: Integrated coolant channels flush chips and cool the cutting edge in real time, reducing heat buildup, preserving accuracy, and enabling deeper, cleaner holes without chatter.
• AlTiN Coating for Wear Resistance: A hard ceramic layer minimizes friction and wear, extending tool life and sustaining sharpness for consistent hole quality across repeated cycles.

Together, these design choices translate into real-world benefits: faster throughput, fewer interruptions for tool changes, and more repeatable hole quality. The Widin 12.9 mm carbide drill maintains dimensional accuracy through long production runs, reduces heat-related distortion, and supports a steadier workflow from start to finish.
