Widin Carbide Drill Through Coolant 3xD AlTiN Coated - 17.7mm is a solid carbide drill designed for through-coolant drilling, delivering dependable performance for professionals and hobbyists alike. Its rugged construction and coated edge provide long tool life and consistent hole quality, even in demanding materials.

With an AlTiN coating, it offers exceptional wear resistance, high hardness, and low friction to help you cut more reliably between tool changes. The 3xD length balances reach and rigidity, while the through-coolant design ensures efficient chip evacuation and cooling, protecting the tip and maintaining dimensional accuracy across depths.

• Through-Coolant for Efficient Chip Evacuation: Delivers coolant directly to the cutting edge and clears chips quickly, reducing heat buildup and helping maintain precise hole sizes across a range of materials.
• Hardwearing Carbide Core with AlTiN Coating: Provides outstanding durability and stiffness with a wear‑resistant, low‑friction coating that extends tool life and preserves cutting efficiency.
• 3xD Length for Versatility and Stability: Offers practical reach for different hole depths while preserving rigidity, reducing deflection and delivering straighter, more accurate holes.

Together, these features translate to longer tool life, fewer interruptions, and more consistent hole quality. The through-coolant design and AlTiN-coated carbide work together to keep temperatures down and wear low, enabling faster cycles and lower rework. Whether you’re tackling steel, aluminum, or other challenging materials, this drill helps you complete jobs with confidence and efficiency.
