## Summary description

FANAR GWINTOWNIK M4 DIN-371B EL (6H) HSSE TN 800X is a machine tap for creating M4 metric threads. Built to DIN-371B dimensions, it features HSSE (high-speed steel with cobalt) material for increased wear resistance and an EL flute style. Intended for industrial and workshop tapping operations in metals where M4 threads are required.

## Long description

FANAR GWINTOWNIK M4 DIN-371B EL (6H) HSSE TN 800X is a machine tap designed to produce M4 metric internal threads with dimensions conforming to DIN 371B. Manufactured from HSSE (high-speed steel with cobalt), this M4 machine tap offers enhanced wear resistance and thermal stability compared with standard high-speed steels. The tap features an EL flute geometry and is intended for industrial and workshop tapping operations in a variety of metals where precise M4 threads are required.
Advantages
The HSSE material composition improves tool life and resistance to softening at elevated cutting temperatures, while the DIN-371B profile ensures consistent thread form and tolerance (6H fit). EL flute geometry facilitates chip evacuation and stable cutting when machining common metallic materials. The tool is suitable for repeated production use and repair operations where dimensional accuracy and surface finish of internal M4 threads are important.
Suitable for
Creating M4 metric internal threads in ferrous and non-ferrous metals
Workshop and industrial tapping operations
Repairing or reconditioning worn M4 threads
Batch production where repeatable thread tolerance is required
Key specifications
Thread size: M4 metric
Thread profile standard: DIN 371B
Tolerance class: 6H (fit for internal threads)
Material: HSSE (high-speed steel with cobalt)
Flute style: EL flute geometry
Intended use: machine tap for tapped holes
How to use
Select an appropriate drill size for the M4 tap drill hole and secure the workpiece. Use suitable tapping fluid or coolant when machining metals to reduce friction and improve tool life. Mount the machine tap in the appropriate holder or machine spindle and run at speeds and feeds recommended for HSSE taps and the specific workpiece material. Apply steady feed while ensuring proper chip evacuation; reverse briefly to break chips if necessary. After tapping, clean the thread and inspect for dimensional accuracy and surface finish.
Usage recommendations
For best results, match cutting speed and feed to the workpiece material and use appropriate lubrication. When machining harder alloys, reduce speed to account for the cobalt-alloyed HSSE composition. Regularly inspect the tap for wear and replace when thread quality or dimensional accuracy degrades.
