RUKO MGB-DIN371-HSSCo-vap.-M2,5x0,45mm Macho de roscar à máquina

Threading small-diameter through holes in tough materials demands a tap that resists heat and wear. The RUKO MGB-DIN371-HSSCo-vap. M2.5x0.45 machine tap is built from high-speed steel with cobalt (HSS-Co) and steam tempered for a hard, lubricant-retaining surface. It cuts metric coarse threads to ISO 2 (6H) tolerance in unalloyed and alloyed steels up to 800 N/mm², stainless steels, cast iron, and non-ferrous metals.

Who is it for

Machinists and maintenance technicians who need reliable thread production in small diameters, especially in stainless or high-strength steel. The spiral point design pushes chips forward, making it ideal for through holes.

Main features

• HSS-Co with vaporized (steam tempered) surface for improved wear resistance and chip evacuation
• Spiral point flute geometry for through-hole threading
• DIN 371 Form B with reinforced shank and square drive
• Right-hand cut for standard clockwise threading
• Precision ground to ISO 2 (6H) tolerance class
