Flex 5.5" Backing Pad for XC 3401 VRG Polisher — 6¼" Diameter, 10,800 RPM Rated

Flexible, firm 5.5-inch backing pad designed for the Flex XC 3401 VRG polisher, offering a smooth, hook-and-loop surface for secure pad attachment up to 10,800 RPM.

This backing pad is a purpose-built accessory for the Flex XC 3401 VRG rotary/orbital polisher. Crafted for professional detailing and workshops that need a reliable interface between polishing pads and the machine, it balances a half-inch thickness and a smooth face to support even pressure distribution across aluminum, fiberglass and metal panels. The pad’s hook-and-loop fastening simplifies pad changes while its 6 1/4-inch outer diameter provides broad coverage for faster correction and finishing passes.

What exactly does this backing pad do for my polisher?

The backing pad provides a stable, cushioned platform that attaches polishing or finishing pads to the XC 3401 VRG. It transmits the polisher’s motion evenly to the pad, helping achieve consistent results across the workpiece while preventing pad slippage.

• Ensures secure hook-and-loop connection between pad and tool
• Smooth surface minimizes imprinting or pattern transfer
• Half-inch thickness offers balanced stiffness and compliance
• Compatible with rotary and orbital movements of the XC 3401 VRG

How does it perform with different materials like aluminum or fiberglass?

This pad is suitable for aluminum, fiberglass and metal surfaces when used with appropriate polishing pads and compounds. Its design supports controlled pressure and uniform contact, which helps maintain material integrity while polishing or finishing.

• Broad 6 1/4" diameter covers large areas quickly
• Smooth texture prevents surface marking on soft metals and composites
• Works with a range of foam, wool and microfiber pads

Is it safe to use at high speeds and how durable is it?

The backing pad is rated for operation up to 10,800 RPM, matching the demands of high-speed polishing tasks when paired with the correct Flex model. Constructed and finished to industrial standards, it withstands routine workshop use and offers consistent performance over repeated service cycles.

• Maximum speed rating: 10,800 RPM for compatibility with high-speed polishing
• Robust construction meant for repeated pad changes and extended use
• German-made quality control for dimensional accuracy and balance

How do I mount and maintain the backing pad?

Attach the pad to the XC 3401 VRG’s drive spindle using the correct mounting thread or quick-change interface, then press the hook-and-loop pad onto the backing face. Keep the hook-and-loop surface clean of compound residue and replace the pad if excessive wear or imbalance appears.

• Use firm pressure to seat hook-and-loop pads evenly before operation
• Clean with compressed air or a soft brush; avoid solvents on the loop surface
• Inspect periodically for wear, deformation or lost balance
