Tap & Die Set M3-M12 20pc Metric 1/8in NPT Thread Repair Kit

A 20-piece tap & die set for cutting new threads and repairing damaged ones across a useful range of common metric sizes. It covers M3 x 0.5 up to M12 x 1.75mm and also includes 1/8in NPT, making it a practical option for general thread repair and light fabrication work.

Used for cleaning up worn threads, restoring damaged bolt threads and re-cutting threaded holes, this kit suits garage work, workshop use, vehicle maintenance and DIY repairs. It is handy when working on fixings that have been cross-threaded, corroded or slightly damaged, helping bring parts back into use without replacing every fastener straight away. The inclusion of both metric sizes and 1/8in NPT also makes it useful for buyers who deal with a mix of standard workshop jobs and occasional pipe thread work.

The supplied size range runs from smaller M3 threads through to M12, covering many of the common sizes found in regular repair and servicing work. A bar type tap wrench and die holder are included to help with controlled hand use when starting and turning taps and dies. The 20-piece format keeps the kit straightforward and easy to store between jobs, while the spread of sizes helps avoid switching between separate thread repair tools for routine maintenance tasks.
