RUKO HSS-G úplne brúsený vrták do kovu DIN 338, krížové brúsenie, 9,7 mm

The RUKO SPB-DIN338-HSS-G-Kreuz-9.7mm stands out with its split point geometry, which eliminates the need for center punching and provides immediate self-centering on contact. This fully ground HSS-G drill bit is built for precision and efficiency in demanding metalworking tasks.

Highlights

• Split point (Kreuzanschliff) with 135° point angle for self-centering and reduced thrust
• Fully ground from high-speed steel (HSS-G) for excellent dimensional accuracy and surface finish
• DIN 338 standard ensures consistent quality and compatibility
• Uncoated bright finish reduces chip adhesion and improves chip evacuation

In daily use

This 9.7 mm twist drill bit is suitable for drilling alloyed and unalloyed steel up to 900 N/mm² tensile strength, cast iron, non-ferrous metals, and plastics. The cylindrical shank fits standard drill chucks, and the h8 tolerance guarantees a precise fit. Its 133 mm total length and 94 mm flute length provide ample reach for most workshop applications.
