Description
The OSG Carbide 2 Flute Drill is a solid carbide drill bit designed for precision and reliability in a wide range of drilling tasks. With a 4.4 mm diameter and an uncoated surface, its two-flute design delivers efficient chip evacuation and stable cutting for metalworking, woodworking, and other industrial applications that demand consistent hole quality.
- Efficient chip evacuation: The two-flute design clears chips quickly, reducing clogging, heat buildup, and stall to help you maintain smooth, accurate holes.
- Stable, durable cutting: Solid carbide construction and precise geometry resist wear, delivering consistent hole size and longer tool life across a variety of materials.
- Versatile, uncoated performance: The uncoated finish provides broad material compatibility and predictable results from metal to wood and plastics, with simple setup and minimal adjustments.
This drill helps you punch precise holes with confidence, thanks to its rigid carbide core and reliable chip management. The 4.4 mm diameter suits common drilling tasks and supports consistent setups across projects, while its proven durability reduces downtime and rework. Whether you’re refining components, assembling prototypes, or performing routine maintenance, this drill enhances workflow and overall performance by delivering clean, repeatable results.
