RUKO MGB-DIN371B-vap.-M3x0,5mm strojný závitník

The RUKO GMBH MGB-DIN371B-vap.-M3x0,5mm stands out with its reinforced shank and vaporized surface treatment, offering enhanced durability for demanding through-hole threading tasks. This machine tap is engineered for precision and longevity in high-volume production environments.

Highlights

• Metric coarse thread M3 x 0.5 mm per DIN 371 B
• HSS-E (cobalt high-speed steel) for superior wear resistance
• Vaporized (VAP) surface treatment reduces friction and improves chip flow
• Reinforced shank for added stability during machine operation
• Straight flutes with right-hand cut for through holes

In daily use

Designed for machine tapping of through holes, this tap delivers consistent thread quality in materials where high-speed steel with cobalt is required. The square drive ensures secure torque transmission, while the ISO 2 (6H) tolerance class guarantees interchangeability with standard metric fasteners. The recommended core hole diameter of 2.5 mm allows for optimal thread engagement.
