RUKO SPB-DIN338-TypUNI-HSSCo-12,00 σπειροειδές τρυπάνι HSS-Co 12 mm

The RUKO SPB-DIN338-TypUNI-HSSCo-12,00 is a universal twist drill bit made from high-speed steel with cobalt (HSS-Co) for enhanced heat resistance and wear resistance. With a diameter of 12.00 mm and a split point with 135° point angle, it offers precise centering and reduced walking on a wide range of materials.

Highlights

• HSS-Co material with cobalt for high heat resistance and durability
• Split point with 135° point angle for accurate starting and reduced thrust
• DIN 338 standard dimensions: 151 mm overall length, 101 mm flute length
• Bright surface finish and cylindrical shank for secure chuck grip
• Universal type (Typ UNI) suitable for steel, stainless steel, cast iron, non-ferrous metals, and plastics

In daily use

This drill bit is designed for demanding drilling tasks in alloyed and unalloyed steel, stainless steel, cast iron, non-ferrous metals, and plastics. The cobalt alloying improves hot hardness, allowing higher cutting speeds and longer tool life. The split point geometry ensures accurate hole positioning without a center punch, while the right-hand cutting direction and h8 tolerance provide consistent performance.
