Widin Carbide Drill Through Coolant 3xD AlTiN Coated - 17.5mm is a high‑performance drilling tool designed for professionals and serious hobbyists who demand consistent, reliable results in challenging metals. Built from solid carbide with an AlTiN coating and through‑coolant delivery, it delivers long tool life, efficient chip evacuation, and stable performance across varied hole depths with a 3xD length (about 52.5 mm).

• Through-Coolant Capability: Direct coolant delivery to the cutting edge enhances chip evacuation and cooling, helping prevent heat buildup and maintain precise hole size.
• AlTiN Coating for Wear Resistance: A hard, low‑friction coating reduces wear and keeps the cutting edge sharper longer, extending tool life and improving productivity in hard metals.
• 3xD Length for Versatility: The 3xD design delivers deeper reach while preserving rigidity and stability, enabling accurate drilling across a range of hole depths up to about 52.5 mm.

This combination translates into reliable, repeatable results that save time and reduce downtime. The through‑coolant system keeps chips flowing away from the cut, the AlTiN coating reduces wear, and the carbide core maintains rigidity for clean, accurate holes even in hard metals. Whether you’re building, repairing, or prototyping, you can trust this drill to perform consistently across depths and materials, delivering better surface finish and fewer interruptions to your workflow.
