RUKO SCE-DIN22568-HSS-60°-1-3/4 putkikierteitystappi, G 1 3/4 tuumaa, HSS-E

Precision-ground from HSS-E high-speed steel with cobalt, this RUKO pipe thread tap delivers a 55° flank angle and 11 TPI for clean, accurate G 1 3/4 inch parallel threads in tough materials.

Overview

The RUKO SCE-DIN22568-HSS-60°-1-3/4 is a pipe thread tap manufactured to DIN 22568. It cuts G (BSPP) parallel pipe threads with a nominal size of 1 3/4 inch. The tap is made from HSS-E, a high-speed steel alloyed with cobalt, which provides high hot hardness and wear resistance. The bright finish reduces friction and improves chip flow. With four flutes and a right-hand cutting direction, it is suitable for manual or machine tapping in unalloyed and alloyed steels, non-ferrous metals, and plastics.

What stands out

• HSS-E cobalt steel for extended tool life and high cutting performance
• 55° flank angle conforming to BSPP thread standard
• 11 threads per inch for a 1 3/4 inch nominal diameter
• Four flutes ensure efficient chip evacuation
• Bright finish for reduced friction and corrosion resistance
