Steel construction steel materials provide exceptional hardness and wear resistance, making this step drill suitable for demanding cutting applications. The robust construction helps extend tool life and reduces replacement frequency in tough work environments. Large chip removal design Fully ground spiral grooves maximize chip removal efficiency, reducing sticking and buildup. This design helps maintain smooth operation, improving overall production speed and consistency on compatible machines. Individual packaging Each drill is individually packaged in plastic to maximize protection against damage during storage and transport. This packaging helps ensure the tool arrives in readytouse condition. Compatible with multiple machines Designed for use with CNC machines, machining centers, and engraving machines, enabling versatility across a range of projects and setups. Use scenarios CNC machining or milling of metal panels: drill stepped holes in metal workpieces for fixtures and assemblies with clean finishes and reliable chip evacuation. Machining center prototyping: produce precise stepped holes in metal sheets for rapid prototyping and component fitting, helping improve throughput. Engraving machine or decorative metal work: prepare holes in metal components used in signage, frames, or other decorative applications with consistent performance.
