Metric Tap & Drill Bit Set, Spiral Point Thread Tap & Twist Drill Combo, Titanium-Coated Taps + Roasted Yellow Drill Bits for Metal Wood Plastic, M2/M2.5/M3/M4 Sizes (M4*0.7)

The Athnevy Metric Tap & Drill Bit Set provides a precise, professional solution for creating or repairing metric threads in metal, wood, or plastic. Each set includes a titanium-coated spiral point thread tap and a matching roasted yellow twist drill bit, engineered for strength, accuracy, and smooth chip removal. Constructed from 6542 high-speed steel and M35 cobalt alloy, the tools deliver superior hardness, wear resistance, and long service life. The spiral point design pushes chips downward efficiently, making it ideal for through-hole applications. Perfect for machinists, hobbyists, and repair professionals, this set allows easy thread creation in materials like stainless steel, aluminum, bronze, and carbon steel. Follow proper drilling and tapping techniques for clean, precise, and long-lasting threads. Choose from multiple metric sizes (M2 / M2.5 / M3 / M4) to fit your project’s needs — a dependable companion for any workshop or maintenance toolkit.

• Complete Tap & Drill Combo Set – Multiple Metric Sizes. Includes matching tap and drill bit pairs in M2×0.4, M2.5×0.45, M3×0.5, and M4×0.7 sizes. Each pair is precisely sized for accurate hole preparation and threading — ideal for DIY repair, machine maintenance, and model work.
• Durable HSS & Cobalt Construction – Built to Last. Taps are made from 6542 high-speed steel for excellent hardness and toughness, while drill bits are made from M35 cobalt alloy for superior wear resistance and heat stability. Engineered for extended tool life and consistent results.
• Titanium & Roasted Yellow Finish – Enhanced Performance. Titanium-coated taps reduce friction, resist corrosion, and extend cutting life. The roasted yellow drill bit finish improves surface oxidation resistance and ensures smoother cutting through tough metals.
• Fast & Precise Threading – Designed for Through-Hole Work. Spiral point taps feature downward chip removal for quick, clean, and accurate threading. Ideal for cast iron, aluminum, stainless steel, bronze, and hard plastics. Recommended for use with drill presses or tapping machines.
• Easy Operation Tips – Professional Threading Results. Drill the pilot hole first, then tap vertically at a 90° angle with stable pressure. Use proper cutting oil or lubricant to reduce heat and achieve high-quality, durable threads every time.
