Minnexon is a professional manufacturer of solid carbide cutting tools. Our solid carbide step drill bits, also known as stepped drills or cone drill bits, are designed for accurate and efficient hole making in metal, stainless steel, copper, and brass.
These precision tools combine multiple hole diameters into one drill, saving time, improving accuracy, and reducing tool changes.
Solid Carbide Step Drill Bit Overview
A step drill bit has multiple cutting diameters, or “steps,” along its body. Each step can drill a different hole size in one operation. The solid carbide construction provides excellent hardness, wear resistance, and stability during high-speed cutting.
Step drill bits are ideal for machining thin to moderately thick materials, offering clean holes and smooth finishes with minimal burrs.
Features
High-Precision Carbide Body: Excellent hardness and long service life.
Multi-Step Design: Drill multiple hole sizes without tool change.
Smooth Hole Finish: Produces clean edges and minimal burrs.
High Efficiency: Reduces cycle time and increases production speed.
Stable Performance: Maintains accuracy under high cutting loads.
Applications of Stepped Drill Bit | Cone Drill Bit
Minnexon solid carbide step drill bits are suitable for:
Copper and Brass Machining: Perfect for high-speed drilling with clean surface finish.
Sheet Metal Fabrication: Ideal for electrical panels, enclosures, and brackets.
