Key details that make this tap stand out

• Material: High-speed steel (HSS) for durability and sharp cutting edges that stay true under demanding tapping tasks.
• Coating: Uncoated for versatile use across metals and easy re-sharpening or dressing in the shop.
• Thread direction: Right-hand thread, the standard for most metric fasteners and assemblies.
• Lead: Second lead (double-start) design that accelerates thread formation, improves chip evacuation, and reduces tapping time in through-holes.
• Size & standard: M45x3 with ISO 529 dimensions, ensuring compatibility with common metric components and consistent hole-to-thread quality.

This tap is ideal for machine shops, fabrication floors, and reliable DIY projects where consistent, clean metric threads are essential. The second-lead geometry means you get faster cutting without sacrificing thread depth or accuracy, making it a practical choice for frequent tapping work on steel, aluminum, brass, and other typical machinable metals.

How to get the best results: use an appropriate tap drill size per ISO 529, apply a light cutting fluid or lubricant to reduce heat and extend tool life, and maintain steady, moderate feed pressure while turning the tap in a single, smooth direction. Back off occasionally to break chips and prevent binding, especially on tougher materials. With proper care, this Wiseman HSS tap delivers reliable threads time after time.
