Aikyciu Metric Thread Chaser Set 15‑Piece (7 Taps, 7 Dies, Thread File) — Alloy Steel, Color‑Coded Case

The Aikyciu 15 PCS Metric Thread Chaser Set and Repair Kit is a compact metric tap-and-die set with color-coded tools and a thread file designed to restore and clean damaged bolt and nut threads quickly.

This kit brings together seven metric taps, seven metric dies, and a dedicated thread file in a protective case so you can repair stripped or corroded threads without replacing parts. The tools are made from alloy steel with a wear-resistant coating and hex-shaped bodies to accept common wrenches or sockets. Color-coding helps you pick the right metric size fast, and the included thread file lets you correct damaged external threads that taps or dies can’t reach.

What exactly is included and why does each piece matter?

The set contains 15 pieces: 7 metric taps, 7 metric dies, and 1 thread file organized in a molded storage case. Taps clean and restore internal threads, dies re-cut external threads, and the file smooths damaged sections that interfere with engagement.

• Seven metric taps sized for common automotive and machine threads
• Seven matching metric dies for external thread repair
• One thread file for precision reshaping of external thread peaks
• Molded case and color-coding (gold marking) for quick selection and transport

How does this kit perform on worn or corroded threads?

The taps and dies are hardened alloy-steel with a protective coating to resist wear while cutting new thread profiles into damaged fasteners and threaded holes. They remove rust, corrosion, and dirt without excessively removing base material, restoring reliable engagement for bolts and nuts.

• Precision-ground cutting edges recover faded thread profiles
• Coated alloy steel extends tool life under frequent use
• Thread file refines burrs and damaged peaks that taps/dies can miss
• Hex-shaped bodies let you apply consistent torque with standard wrenches

Can I use this for automotive and industrial repairs?

Yes — the metric range and robust construction make the set suitable for automotive, mechanical and light industrial maintenance tasks. It’s intended for repairing existing threads, which helps avoid costly part replacements and keeps equipment in service longer.

• Covers common metric sizes found in cars, motorcycles, and machinery
• Portable case keeps the set ready for field service or shop benches
• Compatible with standard sockets and wrenches for easy application
• Good choice for maintenance, fabrication, and DIY projects

How should I store and care for the taps, dies, and thread file?

Keep tools clean and dry after use, apply a light protective oil to prevent corrosion, and return items to the molded case to avoid damage. Using proper cutting lubricant while rethreading reduces wear and improves finish quality.

• Clean chips and debris from cutting edges after each use
• Use cutting oil for smoother cutting and longer tool life
• Store in the included case to keep sizes organized and protected
• Inspect cutting edges periodically and replace if chipped or rounded
