3 Pcs M3 x 0.5 Tap and Drill Bit Set, High Speed Steel Spiral Point Tap with 3 Pcs 2.5mm Drill Bit, Professional Metric Threading Tool Kit for Metalworking Automotive and DIY Projects

This professional M3 x 0.5 three-piece tap and drill set is designed to meet your various threading needs in metalworking, automotive repair, and DIY projects, combining precision and durability. Crafted from high-speed steel and M35 cobalt alloy with an advanced titanium coating, these tools offer superior rust resistance and lower cutting friction, ensuring lasting performance even when machining hard materials such as stainless steel, cast iron, aluminum, bronze, and hard plastics. The innovative spiral tap design allows for smooth downward chip removal during threading, resulting in clean, precise, and burr-free threads in through holes and shallow blind holes. It significantly improves work efficiency through fast and accurate tapping performance, suitable for both manual and machine operations. This complete threading solution includes three M3 x 0.5 spiral taps and three perfectly matched 2.5mm drills, designed for machining perfect M3 threads, meeting a range of needs from new threading to repairing damaged or stuck threads. For best results, always drill a pilot hole using the included 2.5 mm drill bit before tapping, maintaining a 90-degree vertical angle. Using suitable tapping oil or lubricant will improve thread quality and extend tool life. The tapping depth should be limited to 1.5 times the tap diameter to prevent tool damage.
