RUKO HGB-DIN2181-HSS-60°-1x

Precision centre holes are the foundation of accurate turning and grinding, and this HGB centre drill delivers exactly that. Its 60° point angle and 1 mm pilot diameter create a clean starting point for subsequent machining operations, preventing drill wander and ensuring concentricity.

Who is it for

Machinists, metalworkers, and toolmakers who need reliable centre holes in workpieces before drilling, turning, or grinding. Suitable for use on steel, cast iron, non-ferrous metals, and plastics.

Main features

• Manufactured to DIN 2181 standard for consistent geometry and performance.
• Made from high-speed steel (HSS) with a bright finish for durability and sharpness.
• 60° point angle for standard centre holes.
• Ground cutting edges for precise and clean hole entry.
