RUKO 102149 punho universal para ferramentas de escarear e rebarbar com haste de 10,0 mm

Machinists and toolmakers use the RUKO UniHG-RU reducing sleeve to mount a 10.0 mm shank tool into a 16.0 mm bore. The sleeve slides into the machine spindle or drill chuck, and the tool is held with high concentricity for accurate work.

• Outer diameter: 16.0 mm
• Length: 40.0 mm
• Material: High-grade tool steel, hardened to HRC 60-62

The H6 bore tolerance and hardened tool steel keep the tool centered and resist wear. The light oil coating protects against corrosion during storage.
