Description
The OSG Solid Carbide Step Drill is a precision tool built for professionals who demand clean, accurate holes with minimal downtime. Featuring a solid carbide core and a 3xD length, this drill is designed to handle a variety of materials with consistent results and reduced rework. Its robust construction and compact profile make it suitable for both shop floors and field work where reliability matters.
- EGIAS-coated solid carbide for extended tool life: The advanced coating reduces wear and loss of sharpness, helping you complete more holes between tool changes and improving overall uptime.
- 3xD length for versatile depth drilling: Three times the diameter length enables deeper, multi-application drilling in a single tool, reducing setup time and increasing productivity.
- Step drill design for efficient, multi-depth holes: Progressive diameters allow for precise hole sizing at multiple depths, delivering reliable results with smooth hole exits and fewer deburring steps.
This drill blends durability with practical performance, providing consistent hole quality across a range of materials. The EGIAS-coated carbide core resists wear in demanding tasks, while the 3xD length minimizes tool changes in setups requiring deeper holes. With its straightforward, reliable design, it supports faster workflows, fewer interruptions, and professional-grade results in everyday machining and fabrication tasks.
