Abrasive sanding disc on cloth backing 125 mm G40, pack of 10 – Polax

Polax abrasive sanding discs on cloth backing, 125 mm diameter, grit G40, supplied in a pack of 10. These discs are engineered for aggressive material removal and shaping on metal, wood and other substrates where a coarse grit is required. The cloth backing increases tear resistance and flexibility, allowing consistent contact on contoured surfaces and reliable performance when used with rotary sanders and angle grinders.

Advantages

The cloth-backed construction offers improved durability compared with paper-backed abrasives and maintains abrasive integrity under higher pressure and elevated temperatures. The coarse G40 grit provides rapid stock removal and effective surface shaping. A uniform abrasive layer ensures predictable wear and reduces the need for frequent disc changes. The 125 mm diameter is compatible with a wide range of hand-held and bench-mounted rotary tools, supporting efficient workflow in workshop and industrial settings.

Suitable for

• Removing rust, scale and paint from metal surfaces
• Shaping and leveling wood and composite materials
• Rough grinding before finer sanding steps
• Edge work and contour sanding on curved components
• Surface preparation prior to welding, painting or coating

Key specifications

• Diameter: 125 mm
• Grit size: G40 (coarse)
• Backing material: cloth for enhanced strength and flexibility
• Suitable tool types: rotary sanders and angle grinders with appropriate backing pad
• Pack quantity: 10 discs
• Typical applications: metalworking, woodworking, surface preparation

How to use

Fit a compatible backing pad to the rotary sander or angle grinder, ensuring secure attachment before operation. Match the 125 mm disc to the pad diameter and align any centre hole if present. Operate the tool at recommended speeds for the disc and the workpiece material, applying steady, even pressure and allowing the abrasive to do the cutting to avoid premature wear. Move the tool across the surface in overlapping passes to achieve consistent material removal. Replace discs when the abrasive surface is worn, torn or clogged to maintain efficient performance.

Usage recommendations

Use appropriate personal protective equipment including eye protection, hearing protection and respiratory protection when sanding. For best results on metal, start with G40 to remove heavy material and follow with progressively finer grits. Avoid excessive pressure and prolonged dwell in one spot to reduce heat buildup and extend disc life. Store discs in a dry environment away from direct sunlight and extreme temperatures to preserve backing flexibility and abrasive adhesion.
