M6 DIN 371B Macho de roscar à máquina HSSE TiN 6H ranhura reta Forma B

Threading M6 holes in tough steels or high-volume production demands a tap that won't dull or snap mid-job. This M6 machine tap solves that with a cobalt-enriched HSSE body and a titanium nitride coating, giving you the edge retention and heat resistance to cut clean, accurate 6H threads time after time.

Who is it for

Machinists, metalworkers, and maintenance technicians who need reliable thread cutting in steel, cast iron, and non-ferrous metals. Ideal for through holes and blind holes with sufficient depth, where a Form B lead chamfer (3.5–5 threads) balances easy starting with full thread depth.

Main features

• Metric coarse M6 × 1.0 mm thread to DIN 371B standard
• HSSE high-speed steel with cobalt for superior hardness and heat resistance
• Titanium nitride (TiN) coating reduces friction and extends tool life
• Straight flute design for efficient chip evacuation in most materials
• Thread tolerance class 6H for standard internal threads
• Form B lead chamfer with 3.5–5 threads for versatile use
• Right-hand cutting direction
• Overall length 80 mm, thread length 19 mm, shank diameter 6.0 mm

Tips

Use a suitable cutting fluid or tapping paste to further extend tool life and improve thread finish. Ensure the tap is aligned perpendicular to the workpiece and use a consistent feed rate to avoid breakage.
