Widin Carbide Drills Solid 3xD AlTiN Coated - 12.3mm are high-performance drill bits built from solid carbide, designed for demanding metalworking tasks. With a 12.3 mm diameter and a 3xD flute length, they deliver strong rigidity and versatility for a range of drilling depths, making them suitable for professional fabrication, maintenance, and hobbyist projects alike.

Coated with AlTiN, these drills resist high cutting temperatures and reduce friction, helping you maintain sharpness and achieve clean, accurate holes even in tougher materials. The coating also supports better chip evacuation and lowers tool wear, which means fewer tool changes and more dependable performance over longer runs.

• Solid carbide construction: Delivers exceptional hardness and long tool life, maintaining consistent hole quality across demanding metals and thicker materials.
• AlTiN coating for high heat resistance: Reduces friction and dissipates heat to keep cutting edges sharper longer, enabling stable performance under tougher cutting conditions.
• 3xD length design for rigidity and versatility: Balances stiffness with reach, allowing accurate drilling at various depths without deflection or chatter.

These drills help you move from setup to finished holes more efficiently, with reliable results you can trust across projects. The robust carbide core and AlTiN coating work together to minimize downtime, maintain consistent hole quality, and support productive workflows from prototype work to full-scale production.
