RUKO HGB-DIN352-HSS-60°-3/8 Hand Tap M8 x 1.25 mm, HSS, DIN 352, Through Holes

The RUKO HGB-DIN352-HSS-60°-3/8 hand tap is engineered for cutting metric coarse threads in through holes with precision and durability. Unlike standard taps, its 60° flank angle and 3-flute design ensure efficient chip evacuation and clean thread profiles in general-purpose steels, non-ferrous metals, and cast iron.

Highlights

• High-speed steel (HSS) construction for wear resistance and long tool life
• DIN 352 standard for consistent thread geometry and interchangeability
• Right-hand cutting direction with 6H tolerance class for standard fits
• Square drive shank (4.9 mm) for secure tool holding

In daily use

This tap is suitable for manual or machine tapping of through holes. Its bright finish reduces friction and aids chip flow. The M8 x 1.25 mm thread size is common in general engineering and maintenance tasks.
