Broca helicoidal RUKO SPB-DIN338 HSS-G 8,1 mm, afiação em cruz 135°, DIN 338

Precision-ground HSS-G twist drill bit with 8.1 mm diameter and 135° split point for self-centering starts in steel, cast iron, non-ferrous metals, and plastics.

Overview

The RUKO SPB-DIN338 HSS-G Kreuz drill bit is engineered for general-purpose drilling in materials up to 900 N/mm² tensile strength. Its bright, uncoated finish and ground-from-solid construction ensure consistent performance and dimensional accuracy according to DIN 338, with a cylindrical shank and right-hand cut.

What stands out

• 135° split point eliminates walking and reduces thrust pressure.
• HSS-G (high-speed steel, ground) provides a sharp, durable cutting edge.
• DIN 338 standard geometry with 117 mm total length and 75 mm working length.
• h8 tolerance for precise hole sizing in demanding applications.
