RUKO SPB-DIN338-HSS-G-Kreuz-16,5mm punta elicoidale

Precision-ground HSS-G twist drill bit with 16.5 mm diameter and split point for fast, self-centering drilling in steel up to 900 N/mm².

Overview

The RUKO SPB-DIN338-HSS-G-Kreuz-16,5mm is a high-performance twist drill bit manufactured from high-speed steel (HSS-G) and ground from solid to DIN 338 standards. It features a 135° split point tip that eliminates walking and reduces thrust pressure, making it ideal for accurate hole positioning in alloyed and unalloyed steel, cast iron, non-ferrous metals, and plastics.

What stands out

• Split point (Kreuzanschliff) geometry for self-centering and reduced drilling force
• Ground from solid for superior accuracy and surface finish
• Bright finish for clean cutting and corrosion resistance
• Right-hand cutting direction, cylindrical shank
• h8 tolerance for consistent hole quality
