SDFTools Custom Tooling:Precision and Efficiency Combined
At SDFTools, we specialize in custom-designed internal coolant step drills that streamline your machining process. These tools are engineered to create multi-level step holes and chamfers in a single operation , saving time, reducing tool changes, and ensuring superior surface finishes.

Key Features of Our Internal Coolant Step Drills
✅ Multi-Step Design :
Effortlessly machine complex stepped holes with different diameters in one pass, eliminating the need for multiple tools or setups.
✅ Integrated Chamfering :
The tool is designed to simultaneously add chamfers, further simplifying the machining process and enhancing efficiency.
✅ Internal Coolant Channels :
Delivers coolant directly to the cutting zone, improving chip evacuation, reducing heat buildup, and extending tool life—especially critical for deep-hole or high-speed operations.
✅ Fully Customizable :
From step configurations to specific dimensions, every drill is tailored to meet your unique application requirements.
