RUKO HGB DIN 2181 HSS 60° Macho de roscar à máquina rosca métrica fina M20 x 1,50 mm

This RUKO machine tap is built for precise internal thread cutting in through holes, featuring a metric fine thread of M20 x 1.50 mm. Unlike general-purpose taps, it is manufactured to DIN 2181 with a 60° thread profile and ISO 2 (6H) tolerance, ensuring consistent thread quality in steel, cast iron, and non-ferrous metals.

Highlights

• Metric fine thread M20 x 1.50 mm for high-precision fastening applications
• Ground from high-speed steel (HSS) for durability and long tool life
• Bright finish reduces friction and improves chip flow
• Square drive shank for secure holding in tap holders
• Right-hand cutting direction for standard threading operations

In daily use

The tap is designed for machine tapping in through holes, where the fine pitch provides a stronger thread engagement than coarse threads. Its HSS construction withstands the heat generated during cutting, while the ground thread profile ensures accurate thread form and pitch diameter. The bright finish helps prevent material build-up on the cutting edges, maintaining clean cuts over repeated use.
