Description
The OSG Carbide Drill 3XD, WD1 Coated, Solid, 7.8mm is a high‑performance solid carbide drill designed for precise drilling across a wide range of materials. Featuring a 3XD (three times diameter) length‑to‑diameter ratio, it provides deep hole capability with stable, reliable performance in a single setup.
The WD1 coating enhances wear resistance and improves chip evacuation, helping you achieve longer tool life and consistent hole quality even in tougher materials like steel and aluminum. This combination makes the drill a dependable choice for production runs, service work, and demanding machining environments.
- 3XD geometry for deep, stable drilling: Delivers deeper holes with improved rigidity and predictable hole sizes, reducing rework and tool changes.
- WD1 coating for wear resistance and chip evacuation: Extends tool life and keeps chips flowing freely for smoother, faster drilling and better finishes.
- Solid carbide construction for rigidity and precision: Ensures tight tolerances, clean hole edges, and reliable performance across common metals such as steel and aluminum.
This drill is built for engineers, machinists, and hobbyists who need durable, accurate drilling tools that deliver consistent results. With its combination of deep‑hole capability, protective coating, and rigid carbide construction, it supports faster setups, fewer interruptions, and dependable performance across a variety of machining tasks.
