HST 359 Back-up pad for Hook & Loop discs

Klingspor HST 359 backing pad for self-fastening discs: designed for medium sanding and polishing

Sanding operations performed with handheld machines at high removal rates are the ideal use scenario for abrasive discs. The most common machines used cases are angle grinders and handheld right angle die grinders. There are two common ways to attach abrasive discs to the backing pad:

  • Screw connection – the abrasive disc is equipped with a centre threaded hole for this type of attachment
  • HST 359: Attachment by hook and loop fastening – in this case, the abrasive disc is equipped with a backing made of velour for a hook and loop surface

A backing pad for self-fastening discs such as the Klingspor HST 359 allows for much easier work

The HST 359 is generally suitable for all applications. Every specific application is matched with the perfect abrasive – aggressive grinding, deburring, rust removal, finishing, polishing or final surface treatment. The HST 359 backing pad for self-fastening discs can be combined with all abrasive discs that Klingspor offers with a self-fastening backing.

Which abrasive is right for the job?

Every application must be matched with the abrasive that is best suited for the job. Rough sanding requires a coarse grit size, while fine sanding or polishing jobs need to be performed with a fine grit size. Hard materials, such as glass, ceramic or mineral-based materials, require a grain of sufficient hardness, while soft, yet tough, materials are sanded with one of three kinds of aluminium oxide grains (aluminium oxide, zirconia or ceramic aluminium oxide). Klingspor carries a matching disc with self-fastening backing for each of these variants, including the specially designed HST 359 backing pad for self-fastening discs. The backing pad has been designed for medium sanding and polishing applications.

Quick and easy change of the abrasive disc thanks to hook and loop fastening

The HST 359 backing pad for self-fastening discs is equipped with a fine self-fastening backing that allows for the secure fastening of abrasive discs with a velour self-fastening backing. The abrasive disc is replaced by simply pulling off the old abrasive by hand. No tools required. The new abrasive disc needs to be positioned as centrally as possible to keep wobbling and any resulting vibrations at a minimum.
