SKU CH-A37E-ERQ29

A 5-inch backing pad with round-hole fastening and a 5/8-11 clamping nut secures resin-fibre discs while airflow through the nut reduces heat buildup during weld removal and blending

  • Product typeAbrasive Finishing Tools
  • Secure disc mounting with 5/8-11 clamping nut
  • Reduces disc overheating through airflow design
  • Impact-resistant pad withstands weld removal tasks
  • Compatible with 5-inch Coolcut and Topcut discs
  • Flexible backing improves finish on curved surfaces

Backing Pad Assembly for 5 Inch Discs

This Walter Surface Technologies backing pad assembly supports 5 inch abrasive sanding discs during finishing work. It is designed for use with Coolcut and Topcut resin fiber discs. The impact-resistant plastic construction helps during weld removal and blending tasks. The pad mounts securely to compatible pneumatic or hydraulic tools.

Heat Dissipation Through Round Hole Fastening

The orange backing pad features a round armor hole fastener with a 5/8-11 inch clamping nut. This design creates space behind the sanding disc to promote airflow. Improved airflow dissipates excess heat generated during operation. Cooler running protects the abrasive disc and supports consistent performance.

Flexible Support for Curved Surface Finishing

The mountable pad provides flexible backing that conforms to curved surfaces for a finer finish. It replaces worn or damaged backing pads on existing finishing tools. The upgrade is worth it when the current pad no longer holds discs securely or heat buildup affects disc life. This assembly is not for tools requiring different disc diameters or fastening thread patterns.

Questions about this item

How do I install the 5/8-11 clamping nut on the backing pad so the disc stays secure?

Thread the 5/8-11 clamping nut onto the sander spindle, place the orange backing pad against the nut, then tighten the round armor hole fastener until the pad seats firmly against the disc.

Which part of this assembly wears out first and needs replacement?

The impact-resistant plastic back pad and the round armor hole fastener are the consumable components; replace them when the pad surface cracks, loses flexibility, or the fastener threads strip.

What limits continuous operation before the pad overheats?

The 5/8-11 clamping nut creates an airflow gap behind the disc; sustained high-pressure grinding can still overwhelm that cooling, causing the pad to soften or the disc to glaze.
