Description
The OSG Solid Carbide Step Drill is a precision cutting tool engineered for clean, accurate holes across a variety of materials. With a solid carbide body and an EGIAS coating, it delivers durability and wear resistance that professionals rely on for repeatable results. Its 3xD length and stepped geometry let you initiate holes and widen them in a single setup, boosting efficiency in everyday machining tasks.
- 3xD length for deep, multi-depth drilling: Enables deeper holes in a single setup, reducing tool changes and speeding up workflows while maintaining stable guidance for precise results.
- EGIAS coating for longer life: Reduces wear and friction, extending edge life and helping maintain consistent hole quality over many cuts in challenging materials.
- Solid carbide construction for reliability: Delivers rigid, precision-driven performance that stays accurate under load, providing repeatable hole sizes and smooth finishes across applications.
This combination of deep-reach capability, enhanced wear resistance, and rigid carbide construction supports faster setups, fewer tool changes, and consistently clean, accurate holes. It’s a dependable choice for engineers, machinists, and serious hobbyists who demand professional results with every drill operation.
