Hymnorq 6-Piece Metric Combination Drill and Tap Bit Set, HSS M3-M10, 1/4" Hex Shank 2-in-1 Drilling & Tapping Tools, Screw Threading Bit Kit for Wood, Plastic, Aluminum

• 2-IN-1 EFFICIENCY: This combination set is designed to drill the hole and tap the thread in a single operation. By combining two steps into one, it eliminates the need to change bits or use separate tools, significantly speeding up your workflow on repair and fabrication projects.
• COMPLETE METRIC RANGE: Includes 6 commonly used metric sizes to suit various needs: M3x0.5, M4x0.7, M5x0.8, M6x1.0, M8x1.25, and M10x1.5. Each bit is clearly marked with its size for quick identification and comes in a compact storage case.
• 1/4" HEX SHANK: Featuring a universal 1/4-inch hex shank, these bits are compatible with most power drills, impact drivers, and quick-change adapters. The hex design provides a secure grip in the chuck, preventing slippage even under torque.
• HIGH-SPEED STEEL (HSS): Constructed from industrial-grade High-Speed Steel for durability and wear resistance. The bits feature a spiral flute design that helps clear chips out of the hole efficiently, reducing friction and heat buildup during the tapping process.
• VERSATILE APPLICATION: Ideal for drilling and tapping through wood, plastic, and soft metals such as aluminum, brass, and copper. Note: To prevent bit breakage, strictly use low speeds (slow RPM) and apply cutting oil when working with metals. Not recommended for hard metals like stainless steel.
