RUKO SPB-FLS-DIN338-HSS-G-Ø17,5mm-3FLS-puntspiraalboor

Precision-ground HSS-G twist drill bit with a 17.5 mm diameter and three flutes, engineered for clean, accurate holes in steel, cast iron, non-ferrous metals, and plastics. The 135° split point reduces walking and requires less feed pressure, while the DIN 338 standard ensures consistent geometry and compatibility with standard drill chucks.

Overview

This RUKO drill bit combines a robust high-speed steel body with a cross-ground split point for immediate centering and reduced thrust. Its three-flute design improves chip evacuation and stability, making it suitable for both hand-held and stationary drilling in tough materials.
