Backing Pad KLINGSPOR HST 359 125 mm M14 (model 70434)

The KLINGSPOR HST 359 backing pad 125 mm with M14 thread (model 70434) is a flat support plate designed for use with hook-and-loop abrasive discs on angle grinders and sanding machines. It offers a stable contact surface for sanding, grinding and finishing tasks on metal, wood and painted surfaces. The backing pad is intended for workshop and professional use where consistent disc support and easy disc replacement are required.

Advantages

The backing pad provides a uniform, flat support that helps maintain even abrasive contact over the workpiece, reducing the risk of uneven sanding. Its hook-and-loop face allows quick attachment and replacement of abrasive discs, improving workflow efficiency. The M14 threaded connection ensures secure mounting on compatible angle grinders and machines, minimizing vibration and wobble during operation.

Suitable for

• Sanding and smoothing wooden surfaces
• Preparing and finishing metal and sheet metal
• Removing paint, rust and coatings
• Surface preparation before painting or varnishing
• Use with hook-and-loop abrasive discs for general workshop tasks

Key specifications

• Backing pad diameter: 125 mm
• Mounting thread: M14
• Attachment type: hook-and-loop (velcro) face for abrasive discs
• Design: flat support plate for uniform pressure distribution
• Intended tool type: angle grinders and compatible sanding machines

How to use

Ensure the power tool is switched off and disconnected from the power source before mounting the backing pad. Thread the pad onto the grinder's spindle using the M14 connection and tighten securely according to the tool manufacturer's instructions. Attach a compatible hook-and-loop abrasive disc to the pad, pressing firmly to ensure full contact. During operation, hold the tool with a steady, controlled motion and apply consistent pressure appropriate to the workpiece and abrasive grit. Replace worn discs as needed and check the pad for damage before each use.

Usage recommendations

For best results, use abrasive discs that match the 125 mm diameter and hook-and-loop fastening system. Observe the recommended rotational speed limits of both the backing pad and the abrasive disc, and always wear appropriate personal protective equipment such as eye and hearing protection and dust mask when sanding or grinding.
