RUKO MGB-DIN371-HSS-TiAlN-60°-M8x1.25mm Machine Tap

Cutting precise M8x1.25 metric threads in tough materials demands a tap that resists wear and maintains accuracy. The RUKO MGB-DIN371-HSS-TiAlN-60°-M8x1.25mm machine tap solves this with a cobalt-enriched high-speed steel body and a TiAlN coating that reduces friction and heat.

Who is it for

Machinists and metalworkers who need reliable thread production in steels up to 900 N/mm², whether for through holes or blind holes in production environments.

Main features

• DIN 371 standard for machine taps with reinforced shank
• HSS-E (cobalt alloyed) for high hardness and heat resistance
• TiAlN coating for extended tool life and dry machining capability
• Metric ISO coarse thread M8 x 1.25 mm, 60° thread angle
• Form C chamfer (2-3 threads) for general purpose threading
• Straight flutes with 3 flutes for efficient chip evacuation
• Ground thread for precise thread geometry and tolerance class ISO 2 (6H)
