Tap Topex M8 tungsten DIN 352

Topex M8 tungsten DIN 352 is a hand and machine tap designed for producing and repairing M8 internal threads according to the DIN 352 standard. Made from tungsten (hard alloy), this tap delivers increased wear resistance and dimensional stability during repetitive tapping tasks in metalworking and maintenance operations. It is suitable for use in various machines as well as for manual tapping where DIN 352 geometry and tolerances are required.

Advantages

The tungsten construction offers high hardness and extended tool life compared with standard high-speed steel taps, reducing frequency of tool change. Conformance to DIN 352 ensures consistent thread form and compatibility with metric M8 components. The tap is balanced for stable cutting action and provides reliable performance in moderate-to-heavy wear conditions typically encountered in production and repair work.

Suitable for

• Cutting new M8 internal threads in metal components
• Repairing damaged or worn M8 threads
• Hand tapping in maintenance and assembly tasks
• Machine tapping operations requiring DIN 352 specification

Key specifications

• Thread size: M8
• Standard: DIN 352 thread form and tolerances
• Material: tungsten (hard alloy) for improved wear resistance
• Intended use: hand and machine tapping

How to use

Select the correct drill size for the M8 thread and secure the workpiece. For machine tapping, mount the tap in a suitable holder and align it perpendicular to the work surface. Apply a suitable cutting lubricant to the tap and the hole before starting. For hand tapping, use a tap wrench and apply steady, even pressure while advancing the tap; periodically reverse the tap slightly to break chips and clear cuttings. Progress at a controlled speed appropriate to the material being machined and maintain coolant or lubricant to prolong tool life and ensure accurate threads.

Usage recommendations

Use cutting fluid compatible with the workpiece material, avoid excessive feed or torque that can overload the tap, and inspect threads after tapping for compliance with DIN 352 tolerances. Replace the tap if tool wear or chipping is observed to prevent damaged threads.
