The Widin Carbide Drill Through Coolant 3xD AlTiN Coated - 4.2mm is a high-durability drill designed for through-coolant machining. Built for engineers, machinists, and fabricators, it delivers reliable, precise holes with long tool life and stable through-coolant performance.
The solid carbide construction and AlTiN coating resist wear, reduce friction, and help maintain dimensional accuracy, while the 3xD length enables versatile drilling depths without sacrificing stability.

• Solid carbide durability: Long tool life and consistent performance in demanding metals, reducing tool changes and downtime.
• AlTiN coating for wear resistance: Hard, low-friction surface protects against wear, extending tool life and improving cut quality.
• Through coolant with 3xD reach: Efficient chip evacuation and cooling keep temperatures down and maintain accuracy across deeper holes.

This drill helps you complete jobs faster and more reliably. The through-coolant design, paired with the wear-resistant AlTiN coating, reduces heat build-up, minimizes tool wear, and preserves hole dimensions, so you can tackle deeper holes and tougher materials with confidence. Its robust carbide core and length-to-diameter ratio deliver stable cutting performance, fewer reworks, and consistent results that support tighter tolerances and better overall productivity.
