RUKO SPB-DIN338-HSSCo8-Ø8,0mm vrták do kovu

Drilling tough and hard materials demands a bit that resists heat and wear. This RUKO twist drill bit is ground from solid HSS-Co 8% cobalt alloy steel, giving it high heat resistance and increased wear resistance for demanding jobs.

Who is it for

Professionals and serious DIYers who drill alloyed or unalloyed steel, stainless steel, cast iron, non-ferrous metals, and plastics. The 135° split point self-centers and reduces walking, making it ideal for precise, high-performance drilling.
