AWTools AW20264 HSS Threading Tap Set M18 x 2.50mm 3-Piece

The AWTools AW20264 HSS Threading Tap Set is a professional-grade tool kit engineered for creating precise M18 x 2.50mm metric threads. Crafted from high-speed steel (HSS M2) with a hardness of 65° HRC, these taps are built to withstand the rigors of demanding metalworking environments while maintaining sharp, efficient cutting edges. This 3-piece set provides a comprehensive solution for both creating new threads and restoring damaged ones, ensuring compatibility with standard industrial requirements.

Advantages

The primary advantage of this set lies in its high-quality material composition, which offers 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 progressive cutting action that reduces stress on the tool and ensures a clean, accurate thread profile. The inclusion of a durable plastic case keeps the components organized and protected, making it a reliable choice for both mobile maintenance kits and stationary workshop benches.

Suitable for

• Cutting new metric threads in metal workpieces
• Repairing stripped or damaged existing threads
• Manual threading operations in industrial and automotive workshops
• Through-hole and blind-hole threading applications

When it may not be suitable

This set is specifically designed for manual threading operations and may not be suitable for high-speed automated CNC machining or production line environments where machine-specific taps are required. It is intended for use on standard metals and may not perform optimally on hardened steels or exotic alloys that exceed the hardness capabilities of HSS M2 steel.

Key specifications

• Thread size: M18 x 2.50mm
• Material: HSS M2 high-speed steel
• Hardness: 65° HRC (+/-1°)
• Standard: DIN352
• Set composition: 1 taper tap, 1 plug tap, 1 bottoming tap
• Thread type: Right-hand metric

How to use

To use the AWTools threading tap set, start by drilling a hole of the appropriate diameter for an M18 thread. Begin the process with the taper tap, ensuring it is perfectly square to the workpiece to initiate the thread correctly. Follow with the plug tap to deepen the thread, and finish with the bottoming tap if you are working in a blind hole to reach the required depth. Always use a suitable cutting oil to lubricate the tap and clear metal shavings, which helps prevent tool breakage and improves the surface finish of the thread.

What to consider before purchase

• Ensure the workpiece material is compatible with HSS M2 steel
• Verify that the M18 x 2.50mm pitch matches your specific project requirements
• Confirm you have a compatible tap wrench for manual operation
• Check the depth of your hole to ensure the bottoming tap is necessary for your application

Usage recommendations

Always clear metal chips frequently during the threading process to prevent binding and ensure the longevity of the cutting edges. Use a high-quality cutting lubricant to reduce friction and heat buildup.
