Broca curta RUKO SPB-DIN1897-HSS-TiN-Ø6,8mm

Machinists and metalworkers use the RUKO SPB stub drill bit for precise, short-hole drilling in alloyed and unalloyed steel, cast iron, non-ferrous metals, and plastics. Its DIN 1897 short design provides high rigidity, making it ideal for stable, accurate holes in tight setups.

Key specifications

• Type: Stub drill bit (DIN 1897)
• Material: High-speed steel (HSS) with titanium nitride (TiN) coating
• Diameter: 6.8 mm
• Total length: 69 mm
• Working length: 36 mm
• Shank: Cylindrical, h8 tolerance
• Point angle: 118°
• Cutting direction: Right-hand
• Manufacturing: Ground from solid

Why choose it

The TiN coating increases surface hardness, improves wear resistance, enhances heat resistance, and reduces friction, extending tool life and improving hole quality. The short flute design minimizes deflection, ensuring accurate hole positioning and size.

Ideal use cases

• General-purpose drilling in metalworking shops
• Short, rigid drilling applications where precision is critical
• Drilling in alloyed and unalloyed steel, cast iron, non-ferrous metals, and plastics

Good to know

Supplied as a single piece. The gold color is due to the TiN coating.
