Pneumatic tool, 8.500 min-1 - Nitto Kohki 74400001

This group brings together air tools for surface and edge work, from deburring and needle scaling through to surface and fine sanding. Free speeds run from 8.500 to 19.000 min-1 and weights from 0,5 to 2,2 kg.

• The group covers deburring, edge chamfering, needle scaling and grinding, and every tool runs on compressed air with no electrics at the workpiece.
• Free speeds of 8.500 to 19.000 min-1 suit small mounted points as well as sanding pads up to 150 mm.
• Weights of 0,5 to 2,2 kg keep the strain low during longer hand work.
• Air demand ranges from 0,10 to 0,68 m³/min depending on the tool, so smaller units run on an existing workshop compressor.
• Sanding pads, abrasives, spanners and connectors are included depending on the model.
• One model routes dust away at source through a dust hose and dust bag.
