RUKO MGB-DIN371-vap.-35°-M2,5x0,45mm konekierteitystappi

With a 35° helix angle and vaporized HSS-E construction, this DIN 371 machine tap is engineered for efficient through-hole threading in demanding materials.

Overview

The RUKO GMBH MGB-DIN371-vap.-35°-M2,5x0,45mm is a high-performance machine tap designed for creating metric threads in through holes. It features a 35° helix angle that efficiently directs chips forward, preventing clogging and ensuring smooth operation. The tap is made from HSS-E (high-speed steel with cobalt), providing excellent wear resistance and heat resistance, making it suitable for machining unalloyed and alloyed steels up to 800 N/mm², cast iron, and non-ferrous metals.

What stands out

• 35° helix angle for effective chip evacuation in through holes
• Vaporized surface treatment reduces friction and extends tool life
• HSS-E cobalt steel for high hardness and heat resistance
• DIN 371 standard with Form B chamfer (4-5 threads lead) for easy starting
• Precision ground for ISO 2 (6H) tolerance class threads
