RUKO HGB-III DIN 352 HSS 60° M16 x 2.00 mm Left-Hand Hand Tap

This RUKO hand tap is engineered for cutting left-hand metric coarse threads, a configuration that is harder to find than standard right-hand taps and essential for reverse-rotation applications. The HGB-III series follows DIN 352, so the geometry and dimensions are consistent with European tooling standards.

Highlights

• High-speed steel (HSS) body for durability and heat resistance.
• Left-hand thread direction for reverse-threaded holes.
• Metric coarse thread M16 with 2.00 mm pitch.
• 60° thread angle and 6H tolerance class for standard fits.
• Straight flutes with 4 flutes for efficient chip evacuation.

In daily use

The tap has an overall length of 105 mm and a thread length of 30 mm, with a 12.0 mm shank diameter and a 9.0 mm square drive for secure tool holding. The bright finish reduces friction and helps prevent material build-up on the cutting edges. It is suitable for general purpose threading in through holes and blind holes.
