Description
The OSG Solid Carbide Step Drill is a precision cutting tool designed for professionals who need clean, accurate holes at multiple diameters without repeatedly changing tools. Its solid carbide body provides rigidity and long-term performance, and its 3xD length adds reach for deeper work. The tool features an M10x1.5 shank for secure mounting in compatible holders.
Coated with EGIAS, this drill offers enhanced wear resistance, helping to extend tool life and maintain consistent hole quality across a range of materials. The step drill geometry enables progressive hole sizing in a single operation, helping you speed up setups and reduce downtime.
- Step Drill Geometry for Multi-Size Holes: Drills a sequence of hole sizes in one pass, eliminating the need to swap tools and speeding up setups in metal, plastic, and composite workpieces.
- EGIAS-Coated Solid Carbide for Extended Tool Life: The EGIAS coating reduces wear and friction, helping edges stay sharper longer and deliver consistent hole quality even through tougher materials.
- 3xD Length with Stable Shank for Deep Holes: A 3xD length provides extra reach while preserving rigidity, minimizing deflection and ensuring accurate holes in deeper pockets or hard-to-reach areas.
This combination of versatile geometry, durable coating, and extended reach helps you complete drilling tasks faster with reliable, repeatable results. The tool minimizes downtime from tool changes, maintains consistent hole quality across a range of materials, and pairs with standard holders for straightforward setup. Ideal for professional shops, contractors, and serious hobbyists who demand precision and efficiency.
