Widin Carbide Drill Through Coolant 18.0mm is a solid carbide drill designed for through‑coolant machining, delivering durable, reliable hole making in metalworking and fabrication environments. With a 18.0 mm diameter and a 3xD length, this tool provides stable performance across a range of hole depths while preserving precise geometry and a clean finish.

• Through‑Coolant design for efficient chip evacuation: The coolant path along the flute carries chips away from the cutting edge, reducing heat, improving cooling, and helping maintain hole size and surface finish—even in longer or deeper holes.
• AlTiN coating for wear resistance and longevity: The AlTiN coating provides high hardness and low friction, extending tool life and sustaining sharpness for more productive drilling with less downtime.
• 3xD length for versatility and stability: The 3xD length offers reach with rigidity, enabling accurate drilling at varied depths while minimizing deflection in challenging materials.

This combination of solid carbide construction, protective AlTiN coating, and through‑coolant capability helps you achieve consistent hole quality, longer tool life, and more reliable performance in demanding machining tasks—so you can complete projects faster with confidence.
