This precision hand tapping kit is designed for clean, accurate metric threads in metalworking projects, delivering dependable performance from hobbyist repairs to professional shop work. The taps are high-speed steel, ground for a true thread profile, and uncoated to maximize compatibility across a wide range of materials and cutting conditions.

What makes this tap set stand out

• ISO 529 compliance ensures consistent thread form and interchangeability with standard metric threads, so you can trust fit and function every time.
• Metric fine threading with M45x2 right-hand taps, engineered to handle larger diameter applications with precise pitch control.
• High-speed steel, ground finish for smooth cutting action, durable edge retention, and repeatable results across multiple projects.
• Uncoated versatility means reliable performance across a variety of metals, from mild steel to cast iron and certain non-ferrous materials, without coating-induced stickiness or buildup.
