Abrasive Sanding Discs GEKO G78813 225 mm P150 with Holes, pack of 10

GEKO G78813 abrasive sanding discs are 225 mm diameter P150 grit discs with dust-extraction holes supplied as a pack of 10. Designed for use with orbital and disc sanders, these sanding discs provide medium-fine abrasive action suitable for smoothing and preparing wooden surfaces, painted or varnished panels, and composite materials. The pre-punched holes align with standard extractor patterns to help reduce dust during use and maintain clearer working surfaces.

Advantages

These sanding discs combine a consistent P150 abrasive grade with a full 225 mm working diameter to deliver even material removal and surface refinement. The perforated design improves dust collection when used with compatible sanders, which helps prolong abrasive life and reduces airborne particles. Supplied in a pack of 10, the discs offer a straightforward way to replace worn abrasives and keep workflow continuous without frequent reordering.

Suitable for

• Smoothing raw or planed wood prior to finishing
• Preparing painted or varnished surfaces for repainting or refinishing
• Light leveling and blending of composite panels and laminates
• Intermediate sanding between coats where medium-fine abrasive is required

When it may not be suitable

These P150 discs are intended for medium-fine sanding and are not suitable for heavy material removal or shaping tasks that require coarser grits. They are also not the best choice for ultra-fine finishing steps where grits higher than P150 are needed to eliminate sanding marks completely.

Key specifications

• Diameter: 225 mm
• Abrasion grade: P150 (medium-fine)
• Perforation: dust-extraction holes compatible with standard extractor patterns
• Quantity: pack of 10 discs
• Intended tools: orbital and disc sanders

How to use

Attach a disc to the compatible 225 mm backing pad of your orbital or disc sander, ensuring the extraction holes align with the tool's dust port. Start sanding with light, even pressure and progress along the grain or across the surface as appropriate for the material. Replace the disc when the abrasive becomes clogged or worn to maintain consistent sanding performance. Use appropriate personal protective equipment and a dust extraction system when possible.

What to consider before purchase

• Confirm your sander accepts 225 mm discs and has matching hole alignment for dust extraction
• Evaluate whether P150 grit meets your task needs (medium-fine sanding, not heavy stock removal)
• Check whether you require a different abrasive backing type (hook-and-loop or adhesive) for your tool

Usage recommendations

For best results, use these GEKO 225 mm P150 discs with a functioning dust extraction system and maintain light to moderate pressure. Replace discs promptly when performance decreases to avoid surface defects; for successive finishing coats, progress to finer grits as needed.
