AWTools AW20261 HSS Threading Tap Set M12 x 1.75mm 3-Piece

The AWTools AW20261 HSS Threading Tap Set is a professional-grade tool kit designed for creating precise M12 x 1.75mm metric threads. Crafted from high-speed steel (HSS) with a hardness of 65° HRC, this set provides the durability and cutting performance required for demanding metalworking tasks. The kit includes three distinct taps—taper, plug, and bottoming—to ensure a complete and accurate threading process from start to finish.

Advantages

This threading tap set offers exceptional versatility and reliability for both professional workshops and home maintenance projects. The use of high-speed steel ensures long-lasting sharpness and resistance to wear, even when working with tough materials. By providing a three-piece system, the set allows for a gradual and controlled cutting process, which significantly reduces the risk of thread deformation or breakage. The inclusion of a durable plastic case keeps the tools organized and protected when not in use.

Suitable for

• Creating new metric threads in metal workpieces
• Repairing damaged or stripped existing threads
• Mechanical repairs and automotive maintenance
• Workshop projects requiring high-precision threading
• Through and blind hole threading applications

When it may not be suitable

This set is specifically designed for M12 x 1.75mm metric threads and will not work for other thread sizes or pitches. It is intended for use on metal and may not be suitable for extremely hard alloys or non-metallic materials where specialized tooling is required.

Key specifications

• Material: HSS M2 high-speed steel
• Hardness: 65° HRC (+/-1°)
• Thread type: Metric right-hand
• Thread size: M12 x 1.75mm
• Set composition: 1 taper tap, 1 plug tap, 1 bottoming tap
• Standard: DIN352
• Weight: 122 g

How to use

Begin by securing the workpiece firmly in a vice to prevent movement. Start the threading process using the taper tap, ensuring it is perfectly square to the hole. Apply consistent pressure while rotating the tap clockwise, backing off slightly every half turn to clear 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 need to reach the very bottom of a blind hole. Always use appropriate cutting oil to lubricate the process and extend the life of the taps.

What to consider before purchase

• Verify that the M12 x 1.75mm specification matches your project requirements
• Ensure you have a compatible tap wrench for manual operation
• Confirm the material you are threading is compatible with HSS tools

Usage recommendations

Always use a high-quality cutting lubricant during the threading process to prevent overheating and ensure a clean, smooth thread finish. Clean the taps thoroughly after each use and store them in the provided plastic case to prevent corrosion and damage.
