Why choose it

HSS construction ensures taps and dies stay sharp and resist wear, even when working with tough materials like stainless steel. The adjustable wrenches provide a secure grip on both taps and dies, reducing the risk of slipping and thread damage. The included pitch gauge helps you quickly identify thread pitch, saving time and preventing mismatched threads.

Ideal use cases

• Repairing damaged internal threads in engine blocks, gearboxes, and frames
• Cutting external threads on bolts, studs, and custom rods
• Cleaning and chasing existing threads to remove rust or debris
• General maintenance in automotive, motorcycle, and machinery workshops
• DIY projects requiring precise metric threading

Good to know

The set comes in a durable plastic case with designated slots for each tool, keeping everything organized and protected. The adjustable die stock accepts standard 25 mm round dies, allowing you to expand the set with additional sizes if needed. Always use cutting oil when threading to prolong tool life and achieve cleaner threads.
