RUKO SPB-DIN1897-HSSCo broca curta 10,0 mm

Precision-ground stub drill bit with 5% cobalt high-speed steel for tough materials. The 130° split point self-centers and reduces walking, while the short flute design provides maximum rigidity for accurate holes in alloyed and unalloyed steel, stainless steel, cast iron, and non-ferrous metals.

Overview

This RUKO stub drill bit conforms to DIN 1897 and is manufactured from solid HSS Co 5% (high-speed steel with 5% cobalt). It features a bright, uncoated surface and right-hand cutting with a cylindrical shank. The 10.0 mm diameter with h8 tolerance ensures precise holes, and the short overall length of 89 mm offers excellent stability in demanding applications.

What stands out

• Split point (cross-ground) for self-centering and reduced thrust
• High cobalt content for very high heat resistance
• Short flute length for enhanced rigidity
• Ground from solid for consistent quality
