Thread Tap and Die Set AWTools AW20420 — 110 pieces, metric and UNC/UNF taps and dies

AWTools AW20420 is a 110-piece tap and die set designed for cutting, repairing and cleaning external and internal threads. The set contains a selection of commonly used metric and UNC/UNF taps and dies together with holders and basic accessories, providing a compact solution for manual thread work in workshops, maintenance tasks and DIY projects. Components are arranged in a storage case for organised access and transport.

Advantages

The set provides a wide size range that covers common metric and imperial coarse thread standards, enabling work on bolts, studs and threaded holes without needing multiple separate tools. Included tap and die holders simplify alignment and torque application during manual threading operations. The compact case keeps components organised and reduces the risk of losing small tools. The combination of taps, dies and accessories allows both creation of new threads and restoration or cleaning of damaged threads.

How to use

Select the required tap or die corresponding to the desired thread size and standard. For internal threads, secure workpiece, drill the correct pilot hole, apply cutting fluid, then insert the tap into the tap holder and turn evenly, reversing occasionally to clear chips. For external threads, mount the die in the die holder, align it square to the workpiece and rotate to cut the thread, again using cutting fluid and backing off to clear chips. Use appropriate clamping and safety precautions to avoid tool breakage and to maintain thread accuracy.

Usage recommendations

Use the appropriate pilot drill size for each internal thread, apply a suitable cutting lubricant, and work steadily with controlled turns. Inspect threads frequently while cutting and clean chips from tools and workpiece to ensure consistent results. Store tools dry in the provided case to minimise corrosion and maintain performance.
