RUKO HGB-DIN352-HSS-M33x3.5mm Hand Tap

This RUKO hand tap stands out for its precision-ground HSS-G construction, delivering clean, accurate threads in tough materials. Unlike standard taps, it features a plug tap profile (intermediate taper) that balances easy starting with efficient thread cutting, making it a reliable choice for both professionals and demanding hobbyists.

Highlights

• Precision-ground HSS-G steel for high wear resistance and long tool life
• DIN 352 compliant with ISO 2 (6H) tolerance for standard metric coarse threads
• Plug tap (intermediate) design for versatile use in through and blind holes
• Straight flutes with 4 cutting edges for efficient chip evacuation
• Bright finish reduces friction and prevents material build-up

In daily use

With a nominal diameter of 33 mm and a 3.5 mm pitch, this tap is ideal for creating or repairing coarse metric threads in unalloyed and alloyed steels up to 800 N/mm², cast iron, and non-ferrous metals. The right-hand cutting direction and square drive (20 mm) ensure secure holding in standard tap wrenches. Its overall length of 190 mm and thread length of 65 mm provide ample reach and cutting depth for a wide range of applications.
