HST 555 A

Clean sanding with next to no dust thanks to the multihole backing pad HST 555 A for the BOSCH GEX-150 series

Each individual application and material requires a different sanding technique and equipment. While high-speed abrasive discs are needed for particularly aggressive sanding, belt sanders are the right choice whenever an application calls for high removal rates on surfaces or during deburring. Finally, random orbital sanders are the tools of choice for users who need to produce a clean surface finish. These machines combine an oscillating motion with the rotation of an abrasive disc. This allows them to produce a smooth surface without any swirl marks. The benefits of a random orbital sander are

• easy handling,
• sanding results without any swirl marks,
• quick change of the abrasive disc by a hook and loop fastener
• a clean work environment thanks to an extraction option for dust, debris and chips.

Extraction of dust and debris through the multihole backing pad HST 555 A

Professional tools such as the random orbital sander BOSCH GEX-150 can be connected to a central extraction system via flexible tubes. Dust and debris are discharged directly where they are produced thanks to holes machined into the backing pad and the matching holes in the abrasive disc. This keeps the workstation nice and clean. Another advantage is that no particles are expelled into the air. The backing pad HST 555 A by Klingspor fits perfectly on the random orbital sander BOSCH GEX-150. The hardness of the backing pad is in the medium range.

Fine and resistant to heat, the self-fastening support securely keeps in place abrasive discs that are laminated with a non-woven hook and loop surface or velours. This fastening system makes it a snap to change the abrasive disc by hand and without the need for any tools. The Klingspor multihole backing pad HST 555 A has a standard diameter of 150 mm and comes in a range of hardnesses.
