RUKO HSS-E Co 5 morseconus-spiraalboor 15,5 mm DIN 345 MK2

This RUKO twist drill bit is built for demanding metalworking tasks. The HSS-E Co 5 cobalt alloy maintains hardness at high temperatures, and the split point design reduces walking on tough materials like stainless and high-alloy steels.

Highlights

• 15.5 mm diameter with Morse Taper Shank MK2 for secure tool holding
• Ground from solid HSS-E Co 5 (5% cobalt) for durability and heat resistance
• Split point geometry for self-centering and reduced thrust pressure
• DIN 345 standard ensures consistent dimensions and performance

In daily use

The 130° point angle and bright finish help the bit cut cleanly and clear chips efficiently. The Morse taper shank fits directly into matching machine spindles, providing a rigid connection for accurate holes in heavy-duty applications.
