AWTools AW20266 HSS Threading Tap Set M22 x 2.50mm 3-Piece

The AWTools AW20266 HSS Threading Tap Set is a professional-grade tool kit designed for creating and repairing precise M22 x 2.50mm metric threads. Manufactured from high-speed steel (HSS) with a hardness of 65° HRC, this 3-piece set offers exceptional durability and cutting efficiency, making it a reliable choice for demanding industrial and workshop environments. The set adheres to DIN352 standards, ensuring compatibility and consistent performance across various metalworking applications.

Advantages

The primary benefit of this set is its high-speed steel construction, which provides superior wear resistance and heat tolerance during the threading process. By including three distinct types of taps—taper, plug, and bottoming—the set allows for a complete and professional threading sequence, from initial thread alignment to finishing at the bottom of blind holes. The precision engineering of these taps ensures clean, accurate threads, reducing the risk of material damage and improving the quality of the final assembly.

Suitable for

• Creating new metric threads in metal workpieces
• Repairing damaged or worn-out existing threads
• Industrial manufacturing and maintenance tasks
• Workshop projects requiring high-precision threading

When it may not be suitable

This set is specifically designed for M22 x 2.50mm metric threads and is not suitable for other thread sizes or pitches. It is intended for use on metal materials and may not perform optimally on extremely hard alloys or non-metallic materials like plastics or wood, which might require different tool geometries.

• Thread size: M22 x 2.50mm
• Standard: DIN352
• Set composition: 1 taper tap, 1 plug tap, 1 bottoming tap
• Packaging: Plastic storage case

How to use

To use the AWTools threading tap set, first secure the workpiece firmly in a vise. Start the process with the taper tap, which is designed to align the thread square with the hole. Apply consistent pressure and rotate the tap clockwise, using a suitable tap wrench, while frequently reversing the direction to break off metal chips. Once the initial thread is established, follow up with the plug tap to deepen the thread profile. Finally, use the bottoming tap if you are working with a blind hole to ensure the thread reaches the required depth. Always use appropriate cutting oil to lubricate the tool and workpiece to prevent overheating and ensure smooth operation.

What to consider before purchase

• Verify that the M22 x 2.50mm specification matches your specific project requirements
• Ensure you have a compatible tap wrench for the M22 size
• Confirm the material you are threading is compatible with HSS tools

Usage recommendations: Always keep the taps clean and lubricated during use to extend their lifespan. After finishing your work, clean the taps thoroughly and store them in the provided plastic case to prevent damage to the cutting edges.
