Hand tap set Vorel W-24310 — M4 thread, 3 pcs

Vorel W-24310 is a 3-piece hand tap set designed for cutting and repairing internal metric threads size M4. Intended for manual use with a compatible tap wrench, the set contains three taps that correspond to progressive cutting stages — typically taper, second, and plug — enabling controlled thread forming or restoration in metal components and assemblies. The tools are suitable for workshop, maintenance, and light industrial applications where precise M4 internal threads are required.

Advantages

The set offers a compact selection of taps that cover the full sequence of hand tapping operations for M4 threads, reducing the need to purchase individual taps separately. Each tap is shaped for its specific stage of cut, which improves chip evacuation and reduces the risk of thread damage when used with correct technique and lubrication. The tools are compatible with standard manual tap wrenches and are suitable for working in confined spaces where power tapping is impractical.

Suitable for

• Cutting new M4 internal threads in metal components
• Restoring damaged or worn M4 threads in assemblies
• General workshop and maintenance tapping tasks
• Prototyping and light fabrication work requiring M4 threads

Key specifications

• Thread size: M4 internal metric thread
• Set configuration: 3 taps for progressive cutting stages (taper, intermediate, plug)
• Intended use: manual hand tapping with a tap wrench
• Material compatibility: suitable for common metals used in workshop tapping (steel, aluminium, cast iron) when correct speeds and lubrication are applied
• Application areas: metalworking, maintenance, repair and light industrial tasks

How to use

Select an appropriate tap wrench and secure the workpiece in a vise or fixture to prevent movement. Start with the taper tap to establish the thread and ensure correct alignment; apply suitable cutting fluid to the tap and hole. Turn the tap slowly and evenly, reversing periodically to break chips and clear the cut. Progress to the intermediate tap and finally to the plug (or bottoming) tap as required to reach the desired thread depth. Clean chips from the hole and inspect the thread for continuity and fit with an M4 screw or gauge.

Usage recommendations

Use appropriate personal protective equipment, maintain firm alignment during tapping, and apply suitable cutting fluid to extend tool life and improve thread quality. For hardened materials or deep blind holes consider step drilling and careful chip removal to avoid tap breakage.
