RUKO HGB-DIN2181-HSS-60°-Nr.10x Centre Drill, HSS, 6.3 mm Pilot, 20 mm Countersink, 71 mm Length

Creating precise centre holes in workpieces for subsequent machining between centres requires a tool that combines accuracy, durability, and compliance with industry standards. The RUKO HGB-DIN2181-HSS-60°-Nr.10x centre drill is engineered to produce reliable centre holes in materials such as steel, cast iron, non-ferrous metals, and plastics, ensuring proper alignment and support during turning or grinding operations.

Who is it for

This centre drill is intended for machinists, metalworkers, and manufacturing professionals who need to prepare workpieces for between-centres machining. It is suitable for use on lathes, milling machines, and drill presses where accurate centre holes are critical for workpiece concentricity.

Main features

• Manufactured from high-speed steel (HSS) for durability and heat resistance.
• Conforms to DIN 2181 standard for centre drills, ensuring interchangeability and consistent geometry.
• 60° countersink angle provides a proper seat for lathe centres.
• Form A (plain centre drill) without protective chamfer, ideal for general-purpose centre hole drilling.
• Ground finish for precise cutting edges and smooth operation.
• Right-hand cutting direction for standard machine spindle rotation.
