Strojný závitník M12x1,5 DIN 374 C 6H HSSE kobalt rovný pre priechodné otvory

Precision machine tap for metric fine threads, engineered to cut M12x1.5 threads in through holes with a 6H tolerance. The C chamfer (2-3 threads lead) guides the tap smoothly, while the HSSE cobalt steel construction delivers high wear resistance and heat stability for demanding production runs.

Advantages

Ground from HSSE high-speed steel with cobalt, this tap maintains sharp cutting edges even at elevated temperatures. The straight flute design ensures efficient chip evacuation in through holes, reducing the risk of clogging and improving thread quality. The bright finish provides a clean surface that resists material build-up.

Suitable for

• Steels up to 1000 N/mm² tensile strength
• Non-ferrous metals such as aluminium and brass
• Through-hole threading operations on CNC machines or machining centres
• Production environments requiring consistent thread accuracy

Recommendations

Use a suitable cutting fluid or tapping compound to extend tool life. Ensure the tap is correctly aligned with the pre-drilled hole and select an appropriate tapping speed based on the workpiece material. For best results, employ a rigid tapping cycle or a tapping chuck with a
