ST 358

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.

For finish grinding jobs that call for a flexible backing pad

Unlike its sibling, the hard backing pad ST 358 A ribbed, the backing pad ST 358 medium offers good adaptation and shapes to the contours of the workpiece. Performing especially well during surface and finish grinding, this all-purpose tool offers a superb level of temperature resistance.

ST 358 – backing pad comes in various sizes and versions

The backing pad ST 358 is equipped with a locking nut for the fibre discs. It important to make sure that the diameter of the backing pad matches the size of the fibre disc. Klingspor carries all sizes for the ST 358 that are commonly used in the industry.

Grinding at high speed with the backing pad ST 358

Grinding at high speeds allows for a high removal rate. Every fibre disc comes with a specification of its maximum speed, which must not be exceeded:

  • 13,300 revolutions per minute at a disc diameter of 115 mm
  • 12,200 revolutions per minute at a disc diameter of 125 mm
  • 8,500 revolutions per minute at a disc diameter of 180 mm.
