RUKO SPB-DIN338-HSS-G kierrepora ristihiottu 9/32 tuumaa (7,14 mm)

Precision drilling in metalworking shops demands a bit that starts exactly where you aim. The RUKO SPB-DIN338-HSS-G 9/32 inch twist drill bit is built for machinists and maintenance crews who need clean, accurate holes in steel, cast iron, and non-ferrous metals. Its split point geometry eliminates walking, so you can drill without a center punch.

Key specifications

• Diameter: 9/32 inch (7.14 mm)
• Material: High-Speed Steel (HSS-G)
• Standard: DIN 338
• Point type: Split point (Kreuzanschliff)
• Point angle: 135°

Why choose it

The split point design provides self-centering action, reducing the need for pre-punching and improving hole accuracy. Precision grinding ensures consistent geometry and a long tool life, while the bright finish reduces friction and heat build-up during cutting.

Ideal use cases

• Drilling alloyed and unalloyed steel
• Creating holes in cast iron components
• Working with non-ferrous metals like aluminum and brass
• General-purpose drilling in plastics and wood

Good to know

This drill bit is suitable for use in hand drills and drill presses. The cylindrical shank fits standard keyed or keyless chucks. For best results, use appropriate cutting speed and feed rate for the material being drilled.
