RUKO SPB-DIN338-HSS-TiN-Ø11,0mm kierrepora

Precision drilling in metal requires a bit that stays sharp and centered. The RUKO SPB-DIN338-HSS-TiN Ø11.0 mm twist drill bit is built for workshops and manufacturing environments where accuracy and tool life matter. Its titanium nitride coating reduces friction and heat, while the split point design eliminates walking on contact.

Key specifications

• Type: Twist drill bit (DIN 338)
• Material: High-speed steel (HSS)
• Coating: Titanium nitride (TiN), gold colour
• Diameter: 11.0 mm
• Working length: 94 mm
• Total length: 142 mm
• Shank: Cylindrical
• Point angle: 135°
• Point type: Split point (self-centering)
• Cutting direction: Right-hand
• Suitable materials: Steel, cast iron, non-ferrous metals, plastics, wood

Why choose it

The TiN coating increases surface hardness and heat resistance, allowing higher cutting speeds and longer intervals between regrinds. The split point geometry reduces thrust requirements and improves hole positioning accuracy, making it ideal for production drilling where consistency is critical.

Ideal use cases

• Drilling steel and cast iron components
• Non-ferrous metal fabrication
• Plastic and wood drilling when a standard twist bit is needed
• Use in drill presses or handheld drills with a chuck

Good to know

This bit is supplied as a single unit. It is part of the RUKO HSS-TiN series, designed for general-purpose metal drilling with enhanced performance compared to uncoated HSS bits.
