ST 358 Backing pad

Accessories – backing pad ST 358 medium for finish grinding and rust removal

Ultra robust and durable abrasives are a must when it comes to grinding tasks that require a high removal rate. This is why users usually opt for fibre discs when handling these jobs, i.e. fibre discs with a backing made of vulcanised fibre. A flexible backing pad – such as the Klingspor ST 358 – is a better choice for surface and finish grinding.

• 12,200 revolutions per minute at a disc diameter of 125 mm
• 8,500 revolutions per minute at a disc diameter of 180 mm.
