Sia Sianet Multi-Purpose Sanding Discs 150mm P240 Pack of 50

Usage

The Sia Sianet Ø150 P240 multi-purpose discs are designed for fine sanding, finishing, and surface preparation on wood, paint, fillers, and various composites using random orbit sanders in both professional workshops and demanding DIY environments.

Advantages

• Compatible with most 150 mm random orbit sanders for versatile use across brands.
• P240 grit provides smooth finishes suitable for final sanding before painting or varnishing.
• Open mesh construction reduces clogging and enables efficient dust extraction when used with vacuum systems.
• Hook-and-loop backing allows fast disc changes and firm attachment to the sander pad.
• Cuts cleanly across a range of materials, but may wear faster on highly abrasive surfaces compared to heavy-duty alternatives.

Specifications

• Sia Sianet technology: open mesh abrasive fabric enhances dust removal efficiency during operation.
• Tear-resistant synthetic backing extends product life in standard applications; optimized for minimal loading during dry sanding tasks.
• P240 grit size delivers consistent fine abrasion (average grain size approximately 58 microns), suitable for smooth surface results before topcoating or polishing steps.[6]
• Disc diameter: Ø150 mm (6 inches). Supplied as a pack of 50 pieces. Designed specifically for hook-and-loop attachment pads on random orbit sanders.[5]

How it works

Attach the disc’s hook-and-loop side to your sander’s backup pad. The open mesh design lets sanding dust pass through into compatible extraction systems while the P240 abrasive grains efficiently remove fine material layer by layer as you guide the tool over the workpiece.
