Round 8-hole sandpaper with alumina abrasive on the front and flocked self-adhesive felt cloth on the back delivers reliable, long lasting performance for a variety of surfaces and applications. Key benefits - Long lasting and efficient sanding: raw sand with a flocked backing plus special heat treatment provides excellent polishing, antistatic properties, and wear resistance for wood and metal projects. - Strong cutting and reliable sanding: front alumina abrasive offers robust cutting performance with reduced sand shedding, enabling repeated use and quick results. - Clean, dust-free operation: porous vacuum design helps dust stay under control for a cleaner work area and better surface finish. - Easy identification and secure attachment: grit numbers are printed on the back for quick identification; the backing supports quick installation and removal on orbital sanders, and it remains secure during use. Product features - Disc design: Round 8-hole sandpaper suited for standard orbital sanders that use 8-hole dust collection. - Backing and attachment: back is flocked self-adhesive felt cloth for easy pasting and replacement; hook and loop backing allows quick installation and removal and prevents slippage during use. - Abrasive material: front is alumina ore (alumina oxide) for strong cutting force, wear resistance, and consistent performance. - Dust control: porous vacuum design to minimize dust escape during sanding. Suitable applications - Rust removal, deburring, and solder joint grinding on metal surfaces. - Preparation for painting and finishing on bare wood, painted surfaces, and metal. - Polishing and finishing on a variety of complex surfaces including aluminum alloy, rubber, leather, plastic, stone, and glass. Usage scenarios - Woodworking project: prepare bare wood or painted surfaces for coating by smoothing rough areas and removing small imperfections. - Metal fabrication: deburr edges and remove light rust from metal parts, then polish to a smooth, ready-to-finish surface. - Home improvement: sand irregular surfaces on plastic and stone, achieving an even base for paint or sealant. Identification and compatibility - Easy to identify: grit numbers are printed on the back of each disc for quick recognition. - Compatibility: designed for round 8-hole orbital sanding systems, with flexible backing that facilitates quick installation and secure use.
