Macho de rosca para máquina RUKO GEF-DIN2174-HSSCo-TiAlN-60°-M-4x0.7

The RUKO GMBH GEF-DIN2174-HSSCo-TiAlN-60°-M-4x0.7 is a precision machine tap engineered for threading through holes in demanding materials. Its TiAlN coating and cobalt-enriched HSS-E substrate deliver exceptional wear resistance and heat dissipation, ensuring reliable performance in high-speed production environments. Unlike standard taps, this model features a reinforced shank and a 60° thread angle for accurate, clean threads in steel, stainless steel, cast iron, and non-ferrous metals.

Highlights

• TiAlN coating for extended tool life and reduced friction
• HSS-E cobalt steel for high hardness and heat resistance
• Straight flute design with 3 flutes for efficient chip evacuation in through holes
• Reinforced shank for added stability during machining
• DIN 2174 standard ensures consistent geometry and interchangeability

In daily use

Set up your tapping operation with a recommended pilot hole of 3.3 mm. The tap's right-hand cutting direction and ISO 2 (6H) tolerance class produce threads that meet common engineering specifications. Its 70 mm overall length and 13 mm thread length provide a balanced reach for most workpieces, while the 4.5 mm shank diameter fits standard tap holders.
