Thread Tap Set Art-Pol M12x1.25 mm, 2-piece

Art-Pol M12x1.25 mm, 2-piece thread tap set is designed for cutting and restoring internal metric threads M12x1.25 in metal components. The set contains two taps sized and matched for progressive cutting and thread finishing, intended for workshop, maintenance and fabrication tasks where accurate M12x1.25 internal threads are necessary. The tools are suitable for use on common engineering materials in machinery, automotive repairs and general metalworking.

Advantages

The two-piece arrangement allows a roughing tap followed by a finishing tap to produce consistent thread form and dimensional accuracy while reducing cutting forces. The taps are made for repeated use in maintenance environments and provide reliable thread engagement for bolts and fasteners. Compact set format keeps tools organised and ready for on-site or shop-floor operations.

Suitable for

• Cutting new internal M12x1.25 threads in metal parts
• Repairing damaged or worn M12x1.25 threads on machinery and automotive components
• General metal fabrication and prototyping requiring precise metric internal threads

Key specifications

• Thread size: M12 x 1.25 mm (metric fine pitch)
• Set composition: two taps (progressive roughing and finishing)
• Intended application: internal thread cutting and repair in metal
• Typical use environments: workshop, maintenance, automotive repair, metal fabrication

How to use

Select the appropriate tap handle or holder and secure the workpiece. Start with the first (roughing) tap to remove material and establish thread profile, using cutting fluid appropriate for the workpiece material to reduce friction and improve chip evacuation. Back the tap periodically to break chips and clear the flutes. After reaching the required depth, change to the finishing tap to refine thread geometry and achieve the final tolerance. Clean the threads and inspect with a mating bolt or gauge to confirm fit.

Usage recommendations

Use cutting fluid suitable for the material being tapped and maintain steady, even pressure while turning. Avoid forcing the tap; reverse periodically to clear chips. For blind holes, stop before bottoming and withdraw to remove chips. Store taps in a protected case to prevent damage to cutting edges and ensure accurate future performance.
