RUKO MGB-Set-TX-ormB-HSS-M3-M12 Juego de machos de roscar a máquina, 7 piezas, rosca métrica normal, brocas helicoidales, agujeros pasantes, HSS brillante, DIN 371/DIN 376, ISO 2 (6H)

Machine tap set with 7 pieces in metric coarse thread from M3 to M12, made of bright high-speed steel (HSS) and equipped with spiral point flutes (Form B) for reliable chip evacuation in through holes. The set covers the common sizes M3, M4, M5, M6, M8, M10 and M12 in one robust plastic case.

Advantages

Spiral point geometry drives chips forward, preventing clogging and enabling higher cutting speeds in through-hole threading. The bright HSS substrate offers a good balance of toughness and wear resistance for unalloyed and alloyed steels up to 800 N/mm², cast iron and non-ferrous metals. Ground flutes ensure precise thread profiles and consistent performance across the set.

Suitable for

• Unalloyed and alloyed steels up to 800 N/mm²
• Cast iron
• Non-ferrous metals
• Through-hole tapping operations

Recommendations

Use with a suitable cutting fluid or lubricant to extend tool life. For blind holes, consider a set with straight flutes or spiral flutes instead of spiral point.
