The RUKO SPB-DIN338 HSS-G Kreuz 10.0 mm is a precision-ground twist drill bit with a self-centering split point, eliminating the need for pre-punching and reducing feed pressure. Manufactured from solid HSS-G to DIN 338, it delivers accurate holes in steel, cast iron, non-ferrous metals, plastics, and wood.

Highlights

• Split point (Kreuzanschliff) with 135° point angle for self-centering and reduced wandering
• Precision ground from solid HSS-G for durability and consistent performance
• DIN 338 standard dimensions: 133 mm total length, 87 mm working length
• Cylindrical shank fits standard drill chucks; right-hand cutting direction
• Bright, uncoated finish for general-purpose drilling

In daily use

This drill bit is suited for hand drills, pillar drills, and drilling machines. The split point starts on contact without a center punch, and the h8 tolerance ensures a clean hole diameter. Use appropriate speeds and cutting fluid for longer tool life in metal.
