M16 x 2.0 Left Hand Hand Tap Set DIN 352 6H HSS EL-CUT

Hand tap for cutting M16 metric coarse left-hand threads with a 2.0 mm pitch. The EL-CUT treatment on high-speed steel reduces friction, improves chip evacuation, and extends tool life when threading steel, non-ferrous metals, and cast iron.

Advantages

Precision ground to DIN 352 tolerance class 6H, this tap produces threads that meet international standards. Four straight flutes provide efficient chip removal, while the 3–5 thread chamfer eases starting and reduces cutting pressure. The left-hand orientation is ideal for reverse-thread applications such as rotating shafts, turnbuckles, and certain automotive components.

Suitable for

• General purpose internal threading in steel, non-ferrous metals, and cast iron
• Left-hand thread requirements on rotating shafts and assemblies
• Maintenance, repair, and production environments
• Use with a tap wrench or machine holder
