RUKO MGB-DIN2182-HSSCo-60°-Nr.6 Escareador à máquina, cone Morse MK3, 40 mm diâmetro de corte, 140 mm comprimento

Machinists and metalworkers use the RUKO MGB-DIN2182-HSSCo-60°-Nr.6 countersink to create precise 60° chamfers, deburr holes, and prepare surfaces for flat-head screws in steel, cast iron, non-ferrous metals, and plastics. Its HSSCo (cobalt high-speed steel) construction withstands higher temperatures, while the Morse taper shank (MK3) fits directly into machine spindles for secure, vibration-free operation.

Why choose it

The cobalt alloy enhances wear resistance and heat hardness, extending tool life compared to standard HSS countersinks. The three-flute design ensures smooth cutting and excellent chip evacuation, while the Morse taper shank provides a rigid connection for accurate, repeatable results.

Ideal use cases

• Deburring drilled holes in steel and cast iron
• Countersinking for flat-head screws in machine components
• Chamfering edges on non-ferrous metal parts
• Preparing plastic workpieces for assembly

Good to know

For best results, use appropriate cutting fluid and machine speeds based on the workpiece material. The bright finish offers corrosion resistance and easy chip flow.
