RUKO SPB-DIN338-HSS-TiAlN-Ø3,5mm σπειροειδές τρυπάνι

For machinists and metalworkers tackling tough alloys, the RUKO SPB-DIN338-HSS-TiAlN-Ø3.5mm twist drill bit delivers reliable performance in demanding drilling tasks. Its TiAlN coating and split point grind make it a solid choice for precision work in steel, cast iron, and non-ferrous metals.

Key specifications

• Drill bit type: Twist drill bit
• Standard: DIN 338
• Material: High-speed steel (HSS) with TiAlN coating
• Drill diameter: 3.5 mm
• Shank type: Cylindrical, 3.5 mm diameter
• Point angle: 135° (split point)
• Total length: 70 mm
• Working length: 39 mm
• Tolerance: h8
• Cutting direction: Right-hand
• Heat resistance: Up to 800°C

Why choose it

The TiAlN coating reduces friction and increases hardness, allowing for dry machining and longer tool life. The split point design ensures accurate centering and reduces walking, while the fully ground flutes provide efficient chip evacuation.

Ideal use cases

• Drilling alloyed and unalloyed steel
• Working with cast iron and non-ferrous metals
• Precision drilling in plastics
• General purpose drilling in harder materials

Good to know

Manufactured to DIN 338 standards, this drill bit offers consistent quality and dimensional accuracy. Its bronze/grey finish is a result of the TiAlN coating, which also provides high heat resistance for demanding applications.
