MASTERTAP HL M6 x 1.0 Spiral Flute Tap DIN 371 6H HSSE-PM EG

Precision-engineered for high-performance threading, the MASTERTAP HL M6 x 1.0 spiral flute tap delivers exceptional chip evacuation and extended tool life in demanding materials. Its 45° right-hand helix and enhanced geometry (EG) make it the go-to choice for both through and blind holes in steel, stainless steel, cast iron, and non-ferrous metals.

Advantages

Manufactured from powder metallurgy high-speed steel with cobalt (HSSE-PM), this tap combines superior hardness with outstanding toughness. The spiral flute design efficiently lifts chips out of the hole, preventing clogging and reducing the risk of tap breakage. The 6H tolerance class ensures consistently accurate threads that meet DIN 371 standards.

Suitable for

• Threading M6 coarse metric threads in steel and stainless steel
• Blind hole applications where chip evacuation is critical
• General machining in cast iron and non-ferrous alloys
• CNC machining centres and manual tapping operations
