Widin Carbide Drill with Internal Coolant (5.3 mm diameter) is a high-precision drill built for demanding metalworking tasks. Its solid carbide body and TiAlN coating combine to deliver long tool life and reliable cutting performance, making it suitable for engineers, technicians, hobbyists, and workshops that need consistent results.

With an 8xD length and a single-margin geometry, this drill achieves stable, accurate holes and deeper drilling without wandering. The internal coolant channel ensures efficient chip evacuation and effective cooling, helping maintain performance even at higher speeds.

• Durable solid carbide construction: Provides exceptional rigidity and long tool life, maintaining sharpness and reliability through tough drilling tasks.
• TiAlN coating for wear and heat resistance: Enables higher cutting speeds and extended life by reducing wear and dissipating heat more effectively in demanding metals.
• Internal coolant and single-margin stability: Delivers efficient chip evacuation and cooling at the cutting edge, while the single-margin design maintains alignment for consistent, precise holes even at depth.

By combining these design elements, the drill supports faster, more predictable drilling with fewer tool changes and less rework. The robust carbide core, enhanced heat resistance from the TiAlN coating, and active cooling with internal coolant work together to deliver consistent hole quality and improved workflow across production runs and hobby projects alike.
