Set maschi per filettare a mano M12 DIN 352 6HX HSSE INOX EL-CUT 3 pezzi, metrica passo grosso

Threading stainless steel by hand demands a tap that resists heat, wear, and chip clogging — this M12 set delivers all three. Its HSSE cobalt alloy and EL-CUT flute geometry cut clean, accurate metric coarse threads with noticeably lower torque, while the bright finish guards against corrosion in tough INOX jobs.

Highlights

• HSSE (High-Speed Steel with Cobalt) for high wear resistance and heat resistance
• Optimized for stainless steel (INOX) and other tough materials
• EL-CUT flute design ensures efficient chip removal and lower cutting forces
• 3-piece set: taper, plug, and bottoming taps for through and blind holes
• DIN 352 standard with 6HX thread tolerance for reliable fit
• Square drive shank compatible with standard tap wrenches

In daily use

Start with the taper tap to gradually cut the thread, follow with the plug tap for deeper engagement, and finish with the bottoming tap for threads close to the hole bottom. Straight flutes and the bright finish prevent chip clogging and reduce friction, while cobalt steel maintains sharpness over repeated use in stainless steel applications.
