3 Flute Solid Carbide Step Drill Bit Straight Flute Multi Level Cutting Tool for Metal Plastic

3 Flute Solid Carbide Step Drill Bit Straight Flute Multi Level Cutting Tool for Metal Plastic

Introduction:

Our 3-Flute Solid Carbide Step Drill Bit revolutionizes multi-diameter hole-making operations with its innovative straight-flute design. Engineered for precision and efficiency, this advanced cutting tool combines multiple drilling diameters in a single tool, eliminating the need for multiple bit changes. The three-flute carbide construction delivers exceptional stability and chip evacuation, making it ideal for CNC machining centers, automated production lines, and precision manual applications across various materials.

Features:

✔ 3-Flute Straight Design - Provides superior chip clearance and vibration damping compared to traditional spiral flute drills

✔ Multi-Diameter Steps - Single tool performs drilling, chamfering, and countersinking in one operation

✔ Premium Solid Carbide - Offers 5-8× longer life than HSS tools in hard materials

✔ Precision Ground Cutting Edges - Ensures consistent hole quality across all step levels

✔ Optimized Geometry - Special point angle reduces peck drilling requirements

✔ Versatile Material Compatibility - Effective on metals, plastics, and composites

Advantages:

✅ Reduced Cycle Times - Combines multiple operations into one tool path

✅ Exceptional Hole Quality - Produces burr-minimized holes with precise diameters

✅ Improved Process Stability - 3-flute design eliminates chatter in automated applications

✅ Extended Tool Life - Carbide substrate withstands high-temperature machining

✅ Space-Saving Design - Replaces multiple conventional drills in your tool magazine
