RUKO SPB-DIN338-HSS-TiN kierrepora 12,2 mm

For machinists and metalworkers who need a reliable general-purpose drill bit, the RUKO SPB-DIN338-HSS-TiN Ø12.2 mm is a solid choice. Its titanium nitride coating reduces friction and heat, extending tool life when drilling steel, cast iron, non-ferrous metals, and plastics.

Key specifications

• Diameter: 12.2 mm
• Standard: DIN 338
• Material: High-Speed Steel (HSS)
• Coating: Titanium Nitride (TiN)
• Shank: Cylindrical, 12.2 mm
• Overall length: 151 mm
• Flute length: 101 mm
• Point angle: 118°
• Tolerance: h8
• Cutting direction: right-hand
• Manufacturing: ground from solid

Why choose it

The TiN coating provides a hard, low-friction surface that improves chip flow and reduces wear, making this bit suitable for repeated use in production environments. The DIN 338 standard ensures consistent geometry and dimensional accuracy.

Ideal use cases

• Drilling holes in steel components
• Creating pilot holes in cast iron
• Working with non-ferrous metals like aluminum or brass
• Drilling plastics without melting

Good to know

This bit is ground from solid HSS, which offers better concentricity and cutting performance compared to rolled bits. The 118° point angle is suitable for general-purpose drilling in a wide range of materials.
