4-20mm Step Drill Bit

4-20mm Step Drill Bit Highlights

• Versatile Size Range: This step drill bit is designed to create holes of varying diameters, typically from 4mm up to 20mm. This allows for a wide range of applications without needing multiple drill bits.
• Durable High-Speed Steel: Constructed from high-speed steel (HSS), these bits offer excellent hardness and wear resistance. This ensures a longer lifespan and consistent performance when drilling through various materials.
• Clean Hole Drilling: The stepped design allows for progressive hole enlargement, reducing the risk of material distortion or damage. This results in cleaner, burr-free holes compared to standard drill bits.
• Reduced Drilling Pressure: Step drill bits require less pressure to initiate a hole and can drill through thin materials efficiently. This makes them ideal for sheet metal, plastic, and thin wood.
• Single Flute Design: Many step drill bits feature a single flute design which helps to clear chips effectively. This prevents clogging and allows for faster drilling speeds.
