RUKO DOB-HSS-6,5mm broca helicoidal em bruto

Precision drilling in metal and hard plastics demands a bit that stays sharp, centers accurately, and resists wandering. The RUKO DOB-HSS-6.5mm-blank twist drill bit solves this with a ground-from-solid HSS body and a 135° split point that bites instantly without a center punch.

Who is it for

Metalworkers, maintenance technicians, and serious DIYers who need clean, accurate holes in alloyed or unalloyed steel, cast iron, non-ferrous metals, and hard plastics. It works with cordless drills, impact drills, and drill presses.

Use cutting fluid when drilling steel to extend bit life. For hard plastics, reduce speed to prevent melting. The split point eliminates the need for center punching in most materials.
