PTG Thread Tap HSSE DIN 371 M4

The PTG M4 thread tap is a high-performance cutting tool engineered for creating precise internal threads in a variety of metal workpieces. Manufactured from high-speed steel with cobalt (HSSE), this tap offers superior hardness and heat resistance, making it an ideal choice for demanding industrial machining environments. Built to comply with the DIN 371 standard, it features a reinforced shank design that ensures stability and accuracy during machine tapping operations.

Advantages

The primary benefit of this HSSE thread tap is its exceptional durability and wear resistance, which allows for consistent performance even when working with tougher materials. The cobalt content significantly extends the tool life by maintaining cutting edge integrity under high temperatures. Furthermore, the DIN 371 geometry provides excellent chip evacuation and thread profile accuracy, reducing the risk of tool breakage and ensuring high-quality results in professional metalworking applications.

Suitable for

• Machine tapping of M4 internal threads
• Processing various metal materials
• Industrial manufacturing and assembly lines
• Professional workshop machining tasks

When it may not be suitable

This tool is specifically designed for machine tapping and may not be optimal for manual hand-tapping applications due to its shank geometry. Additionally, it is intended for M4 thread sizes and cannot be used for other thread diameters or pitches.

Key specifications

• Thread size: M4
• Material: High-speed steel with cobalt (HSSE)
• Standard: DIN 371
• Application: Machine tapping

How to use

To use the PTG M4 thread tap, ensure the workpiece is securely clamped in a machine vice to prevent movement. Align the tap precisely with the pre-drilled hole, which must be sized correctly for an M4 thread. Use a suitable cutting fluid or lubricant to reduce friction, dissipate heat, and improve the surface finish of the threads. Set the machine to the appropriate speed and feed rate for the material being processed, and ensure the tap is perfectly perpendicular to the surface before starting the tapping cycle.

What to consider before purchase

• Verify that the M4 thread size matches your specific project requirements.
• Ensure your machinery is compatible with DIN 371 standard tools.
• Confirm the material hardness of your workpiece is suitable for HSSE cutting tools.

Usage recommendations

Always use high-quality cutting oil during the tapping process to prolong the life of the tool and ensure clean, accurate thread formation. Regularly inspect the cutting edges for signs of wear or damage to maintain consistent thread quality.
