What Is a Backing Pad?

A backing pad (also called a sanding pad, base pad, or hook & loop pad) is the circular plate that attaches directly to your orbital sander. It provides the hook & loop surface that grips your sanding discs, allowing quick disc changes and secure holding during operation.

When Do You Need a Replacement?

Replace your backing pad when:

• The hook & loop surface no longer grips discs firmly
• Discs fly off during sanding
• The pad is cracked, warped, or damaged
• Dust extraction holes are clogged or worn
• You’re experiencing uneven sanding patterns

Don’t replace if:

• The sander motor itself is failing
• You just need an interface pad for curves (see interface pads below)

Key Features

• ✓ Universal Replacement: 6-inch backing pad with hook & loop surface replaces worn or damaged pads on most orbital sanders — restore your sander’s performance without buying a new tool
• ✓ 44-Hole Dust Extraction: Precision-engineered multi-hole pattern maximizes dust collection efficiency, keeping your work surface clean and extending sander motor life
• ✓ Fits All 6" Sanding Discs: Compatible with all 6-inch sanding discs regardless of hole pattern — 47-hole, 49-hole, 15-hole, 8-hole, and more
• ✓ Professional Grade: Heavy-duty molded construction with durable hook & loop surface; maintains grip strength through hundreds of disc changes
• ✓ Cost-Effective Repair: Save money by replacing just the backing pad instead of the entire sander; easy DIY installation in minutes

Technical Specifications

Compatible Sanders

This 6-inch backing pad with M8 or 5/16"-24 thread is a near-universal standard for professional-grade dual-action (DA) and random orbital sanders. Most pneumatic (air) sanders and many high-end electric models use this specific mounting interface, including:

• Festool ETS 150, RO 150 FEQ
• Mirka DEROS 650CV
• DeWalt DWE6423, DCW210
• Bosch GEX 150, ROS65VC
• Makita BO6030, BO6040
• Most pneumatic DA sanders with M8 or 5/16"-24 spindle thread

Note: Always verify your sander’s spindle thread (M8 or 5/16"-24) before ordering. Check your sander’s manual or measure the existing pad’s center bolt.

Installation Guide

Easy 5-Minute Replacement:

1. Remove old pad: Unscrew the center bolt or twist-lock (depending on model)
2. Clean mounting surface: Remove dust and debris from sander base
3. Install new pad: Align mounting holes and secure with bolt or twist-lock
4. Test: Attach a sanding disc and verify secure grip

Tip: Take a photo of your original pad before removal to ensure proper installation orientation.
