Klingspor ST 358 A Fibre Disc Backing Pad – 125mm × M14 | Hard Ribbed Design | High Temperature Resistant | 126347

Professional Hard Ribbed Fibre Disc Backing Pad for High Stock Removal and Aggressive Grinding

Supply Solutions Group supplies the Klingspor ST 358 A Fibre Disc Backing Pad 125mm (Product Code 126347) to organisations operating across metal fabrication, engineering, stainless steel processing, manufacturing, mining, automotive, pipeline construction and industrial maintenance sectors throughout Australia.

Manufactured by Klingspor, the ST 358 A Fibre Disc Backing Pad is a premium hard ribbed backing pad designed to maximise the performance of 125mm fibre discs during aggressive grinding applications. The rigid ribbed construction supports higher stock removal rates while promoting cool grinding by creating airflow beneath the fibre disc, helping dissipate heat generated during heavy grinding operations. This reduces thermal stress on both the abrasive and the workpiece while improving grinding efficiency.

Designed for use with 125mm fibre discs with a 22mm centre hole, the backing pad features an M14 threaded mount for direct attachment to compatible angle grinders. The hard ribbed profile provides increased stability and grinding pressure, making it ideal for rough grinding, weld preparation, chamfering, edge grinding and heavy material removal. It is supplied complete with a locking nut for secure fibre disc installation.

The ST 358 A is particularly well suited to zirconia alumina and ceramic fibre discs where maximum stock removal and extended abrasive life are required.

As an Indigenous-owned industrial supplier and procurement partner, Supply Solutions Group provides genuine Klingspor abrasive accessories backed by responsive customer service, procurement support and Australia-wide delivery.
