RUKO MGB-TX-DIN371B-HSSCo-M8x1,25mm Macho de roscar a máquina

The RUKO MGB-TX-DIN371B-HSSCo-M8x1.25mm is a high-performance machine tap for threading blind holes in demanding materials. Its cobalt-alloyed high-speed steel (HSSCo) construction delivers superior heat resistance and edge retention compared to standard HSS taps, making it a reliable choice for production environments.

Highlights

• Metric ISO thread M8 with 1.25 mm pitch
• DIN 371 standard with Form B lead-in (4-5 threads)
• HSSCo material for high wear resistance and toughness
• Straight flute design for efficient chip removal in blind holes
• Right-hand cutting direction
• Tolerance class ISO 2 (6H)

In daily use

This tap is intended for machine tapping operations, where it can be used in CNC machining centers, tapping heads, or drill presses. The straight flutes are optimized for blind holes, allowing chips to accumulate in the flutes and be evacuated when the tap is reversed. The bright surface finish reduces friction and improves chip flow. It is suitable for threading steel, stainless steel, cast iron, and non-ferrous metals. The recommended core hole diameter is 6.8 mm.
