Description
The OSG Carbide 2 Flute Drill is a solid carbide drill with a 3.1 mm diameter, engineered for precision and efficiency in everyday drilling tasks. Its two-flute design promotes fast chip evacuation and stable cutting, helping you achieve clean, accurate holes quickly across a variety of materials.
With an uncoated surface, this drill offers versatile use from metalworking to woodworking and other industrial settings. Built for professionals, shops, and serious hobbyists, it delivers reliable performance and consistent hole quality over the long term.
- Two-Flute Design for Efficient Chip Evacuation: The two-flute geometry ensures quick chip clearance, reducing clogging and heat buildup for smoother, more consistent holes.
- Solid Carbide Construction for Durability: Rugged carbide material provides rigidity and wear resistance, delivering long tool life and dependable performance in demanding applications.
- Uncoated Finish for Broad Material Compatibility: Without coatings, it works across a wide range of materials and setups, offering predictable results and easy integration into existing workflows.
This drill helps you streamline drilling workflows by delivering stable, precise holes with fewer passes, reducing downtime and material waste. Its robust carbide construction stands up to repeated use in busy shops, while the uncoated design keeps it versatile across project types—from metal fabrications to woodworking—so you can rely on consistent results and faster production without sacrificing quality.
