Widin Carbide Drill Through Coolant 3xD AlTiN coated, 3.3 mm diameter, is a high-durability drilling solution built for professional shops and serious hobbyists alike. Its solid carbide construction delivers long tool life and dependable performance in demanding materials.

The AlTiN coating reduces wear and friction for extended tool life, and the through-coolant design improves chip evacuation and cooling. With a 3xD length, it handles varied hole depths with stability and precision.

• Solid Carbide Construction: Delivers exceptional durability and consistent results, reducing downtime from wear and enabling reliable performance across demanding drilling tasks.
• AlTiN Coating for Wear Resistance: Provides high hardness and low friction to keep the cutting edge sharp, extending tool life and maintaining cutting efficiency.
• Through-Coolant with 3xD Length: Through coolant enables efficient chip evacuation and cooling during drilling, while the 3xD length offers reach and stability for deeper holes without sacrificing rigidity.

This combination supports faster, more repeatable hole quality, minimizes heat-related tool wear, and helps keep dimensional accuracy consistent across production runs.
