Orion Motor Tech Metric Thread Chaser Set — 15‑pc (M6–M12) Hex Taps & Dies with Thread File and Case

If you work on cars, motorcycles, bicycles, machinery, or household projects, stripped or corroded threads are a common headache. The OMT Metric Thread Chaser Set includes seven taps, seven dies, and a multipurpose thread file in a compact blow-molded case, letting you clean, repair, and restore metric threads in the most commonly encountered sizes. The tools are designed for compatibility with standard socket wrenches and built from coated steel for reliable durability on the job.

What sizes are included and why do they matter?

This set covers seven metric pitches and diameters that show up across automotive and equipment work. Having both fine and coarse pitches for M10 and M12 increases the kit’s versatility so you can match the original thread spec on many fasteners and fittings.

• M6 x 1.0, M8 x 1.25
• M10 x 1.25 and M10 x 1.5
• M12 x 1.25, M12 x 1.5, M12 x 1.75

How does this set make rethreading easier on the job?

The taps and dies are hexagonal to accept a socket wrench, so you can use familiar tools instead of specialized T-handles. The thread file lets you true up external threads and chase damaged pitch flats where taps or dies can’t reach, shortening repair time and reducing frustration.

• Hex-shaped taps and dies for socket-wrench use
• Thread file for external thread correction
• Organized blow-molded case for quick selection and transport

What are the tools made of and how do they resist wear?

Each tool is manufactured from high-quality steel and finished with a protective coating—black oxide or zinc—so they withstand repeated use and resist corrosion. That treatment helps preserve cutting edges and keeps threads from picking up rust, extending service life when stored in the provided case.

• Durable steel construction for strength
• Black oxide/zinc finish for corrosion resistance
• Compact case reduces exposure to moisture and dirt

Can I use this kit on both internal and external threads?

Yes. The set’s taps are intended for internal threads (tapped holes), while the dies and thread file handle external threads on bolts and studs. Together they let you repair mating threads so parts fit correctly again.

• Taps for cleaning and restoring tapped holes
• Dies for rethreading bolt and stud exteriors
• Thread file for partial or damaged external threads

Who is this for: The Orion Motor Tech 15-piece Metric Thread Chaser Set is well suited to mechanics, home DIYers, restoration hobbyists, and maintenance technicians who need a practical, portable kit to recover stripped or corroded metric threads. It’s especially useful when replacing parts is costly or when you want to preserve original fasteners and fittings. Keep it in your bench toolbox, garage, or service van for fast, economical thread repairs.
