RUKO SPB-TX DIN338 HSSCo kierrepora 6,0 mm

Precision-ground 6.0 mm twist drill bit with 5% cobalt alloy for high-temperature drilling in tough steels.

Overview

The RUKO SPB-TX DIN338 HSSCo drill bit is a fully ground twist drill engineered for demanding metalworking. Its HSSCo (High-Speed Steel with 5% Cobalt) construction delivers superior heat resistance and wear resistance, making it suitable for stainless steel, high-alloy steel, cast iron, and non-ferrous metals. The 135° split point reduces walking and provides accurate starts without center punching.

What stands out

• 5% cobalt alloy withstands high temperatures and extends tool life
• Fully ground flutes ensure precise hole quality and efficient chip evacuation
• 135° split point for self-centering and reduced thrust pressure
• Bright finish for corrosion resistance and smooth chip flow
• DIN 338 standard dimensions: 94 mm total length, 57 mm working length
