🔧 Rotary Backing Pads for Grip-Backed Sanding & Polishing Discs – M14 Thread

Right Lines Rotary Backing Pads are designed for use with rotary (non-DA) sanders and polishers, offering a secure and stable base for grip (hook & loop) backed discs. Perfect for sanding, polishing, and surface finishing, these pads come in firm and medium (foam-backed) options to suit various materials and abrasive grades.

These pads are compatible with most M14-threaded rotary tools, including angle grinders, metal polishers, and low-speed sanders.

✅ Key Features:

• Fits most rotary polishers and sanders (M14 female thread)

• Designed for grip-backed sanding, polishing, and diamond discs

• Available in hard (no foam) and medium (foam-backed) versions

• Provides even pressure and consistent contact during sanding or polishing

• Suitable for metal, wood, stone, and composite surfaces

• Ideal for flat and contoured surfaces depending on pad type

📐 Specifications:

• Thread Type: M14 female (fits standard rotary tools)

• Pad Types:

  • Hard Pad: No foam – ideal for coarse abrasives and controlled grinding

  • Medium Pad: Approx. 12mm foam insert – absorbs vibration and enhances finish on finer grits

• Grip Surface: Hook & loop (Velcro-style) backing for fast disc changes

• Recommended Use:

  • Coarse sanding discs with hard pads

  • Finishing and polishing discs with medium foam pads

• Speed Ratings:

  • Rated for angle grinder speeds with lightweight sanding discs

  • For polishing, lower RPM is recommended for control and safety

🛠️ Applications:

• Use with grip-backed:

  • Sanding discs (coarse to fine)

  • Diamond polishing discs (wet/dry – use low speed)

  • Felt polishing pads for final shine

• For finishing:

  • Metal surfaces – stainless steel, aluminium, mild steel

  • Woodwork – smoothing, grain prep

  • Stone & composites – surface refinement and polishing

• Suitable for:

  • Rotary sanders

  • Angle grinders with variable speed

  • Metal polishers (M14 threaded)

🔄 Pad Selection Guide:

⚠️ Not compatible with DA (dual-action) sanders – these pads are for rotary-only machines.

💡 Pro Tip:

When using diamond or felt polishing discs, always reduce speed to low RPM to avoid heat build-up and preserve disc life. Foam-backed pads offer better results on contoured or delicate surfaces.

🧰 Compatible With:

• Grip sanding discs from 60 to 400 grit
