- This round 8-hole sandpaper is built for long-lasting, efficient sanding with a focus on polishing performance. It uses raw sand and a flocked backing with a special heat treatment to deliver excellent polishing, antistatic properties, and wear resistance, making it suitable for both wood and metal surfaces. - Construction and design: The 8-hole round format supports effective dust extraction during use. The front abrasive is alumina ore, while the back features a flocked self-adhesive felt cloth. It provides strong cutting force, wear resistance, and minimizes sand shedding. The design supports repeated pasting, easy and fast operation, and a porous vacuum design to keep dust from escaping. - Versatile applications: Suitable for rust removal, painting preparation, deburring, and solder joint grinding. It can polish a variety of complex surfaces on metal and non-metal materials, including bare wood, painted surfaces and metal, aluminum alloy, rubber, leather, plastic, stone, and glass. - Identification and compatibility: Grit numbers are printed on the back for easy identification. The hook and loop backing allows quick installation and removal of the orbital sandpaper and is designed to stay secure during use.
