Sanding sheet Bosch Expert C470 150 mm K320 multi-hole, pack of 50

Bosch Expert C470 sanding sheets, 150 mm diameter with K320 grit and multi-hole pattern, are designed for fine sanding and surface finishing. These abrasive discs are suitable for use on wood, painted surfaces and primers, providing consistent abrasive performance for final smoothing and preparation before painting or varnishing. Supplied in a pack of 50, they offer a convenient bulk option for workshops, renovation projects and professional tradespeople who use 150 mm orbital sanders that accept multi-hole discs.

Advantages

The C470 K320 sanding sheets deliver uniform surface finish and reduced clogging thanks to their abrasive formulation and multi-hole layout. Their 150 mm size fits standard orbital sanders, and the fine K320 grit enables delicate material removal and smoothing without leaving deep scratches. A pack of 50 ensures uninterrupted work sessions and better cost-efficiency for repetitive finishing tasks.

Suitable for

• Fine sanding and finishing of wooden surfaces
• Feathering and smoothing of painted or primed surfaces
• Preparation of surfaces prior to varnishing or lacquering
• Workshop and renovation tasks requiring consistent fine abrasive performance

Key specifications

• Diameter: 150 mm
• Abrading grade: K320 (very fine)
• Hole pattern: multi-hole for dust extraction compatibility
• Quantity: pack of 50 sheets
• Suitable tool type: orbital (random-orbit) sanders accepting 150 mm multi-hole discs

How to use

Select a 150 mm orbital sander compatible with multi-hole sanding discs and fit the Bosch Expert C470 sheet onto the sander’s backing pad following the tool manufacturer’s mounting instructions. Begin sanding with light to moderate pressure and keep the sander moving across the surface to avoid creating low spots. For painted or primed surfaces, work along the surface contours and check progress frequently to achieve an even, smooth finish. Replace the sheet when abrasive effectiveness declines or clogging affects performance.

Usage recommendations

Use appropriate personal protective equipment (eye protection, dust mask and hearing protection) and a dust extraction system where possible. For best results on delicate surfaces, perform a test on a small area prior to full sanding and progress from coarser to finer grits if larger defects must be removed before using K320 for final smoothing.
