RUKO SPB-DIN338-HSS-TiN spiraalboor 2,1 mm

Titanium nitride coating on a DIN 338 twist drill bit delivers surface hardness up to 600°C heat resistance, extending tool life in alloyed and unalloyed steel, grey cast iron, malleable cast iron, non-ferrous metals, plastics, and wood.

Overview

The RUKO SPB-DIN338-HSS-TiN is a precision twist drill bit with a 2.1 mm diameter, manufactured from high-speed steel (HSS) and ground from solid. It conforms to DIN 338, the standard for short series twist drills with cylindrical shank, ensuring compatibility with standard drill chucks.

What stands out

• Titanium nitride (TiN) coating increases surface hardness and wear resistance, allowing higher cutting speeds and longer tool life.
• Right-hand cutting direction with a 118° point angle for general-purpose drilling.
• Bright polished flutes reduce friction and improve chip evacuation.
• h8 shank tolerance for secure clamping and accurate centering.
