Feature Highlights: 1. High-Speed Steel with Nitrided Finish: Made from durable high-speed steel and treated with a nitrided surface, these taps offer exceptional hardness and superior rust resistance for long-lasting performance. 2. 6-Piece Metric Set (M3-M10): This versatile set includes six taps covering a range of common metric thread sizes from M3 to M10, making it suitable for various threading tasks. 3. Spiral Flute Design: The engineered spiral flutes ensure better chip removal during use, leading to a smoother tapping process and cleaner threads. 4. Combined Drill & Tap Function: Each tool acts as a drill bit and a tap in one, allowing you to drill a pilot hole and cut new threads in a single operation, saving significant time and effort. 5. Machine-Use Optimized: Designed for use with power tools like drills or lathes, these taps enable faster, more precise, and consistent results by minimizing human error during operation. Product Details: This 6-piece set of titanium-coated HSS drill and tap bits is engineered for efficiency and durability. The high-speed steel construction with a nitrided finish provides high hardness and excellent rust resistance. The innovative spiral flute design improves chip clearing for a smoother workflow. Their primary advantage is the combined drilling and tapping function, which streamlines projects by completing two steps in one pass. Optimized for machine use with a standard 1/4" (6.35mm) hexagonal shank, they ensure faster, more accurate, and repeatable results, making them ideal for creating precise metric threads from M3 to M10.
