RUKO SPB-TX-DIN338-HSS-TiN-Ø8,5mm ελικοειδές τρυπάνι

Drilling precise holes in tough steel demands a bit that stays sharp and centered. The RUKO SPB-TX DIN 338 HSS TiN 8.5 mm twist drill bit solves that with a fully ground high-speed steel body and a titanium nitride coating that reduces friction and heat. It cuts cleanly through alloyed and unalloyed steel up to 900 N/mm², cast iron, non-ferrous metals, and plastics.

Who is it for

Metalworkers, maintenance technicians, and serious DIYers who need a reliable general-purpose drill bit for bench drills and pillar drills. It suits anyone drilling steel components, frames, or machine parts where accuracy and tool life matter.

Tips

Use a cutting fluid or lubricant when drilling steel to extend bit life. For deep holes, withdraw the bit periodically to clear chips. Store in a dry place to protect the TiN coating.
