High-quality abrasive for faster cutting and consistent finish: Manufactured with premium aluminum oxide grit that cuts quickly and produces a smooth surface. The open-coat structure delivers an even, consistent scratch pattern while reducing clogging during use. Stearate coating for improved surface finish and reduced loading: The stearate layer helps prevent resin and dust buildup, making sanding more efficient and leaving a cleaner finish ready for polishing or painting. Durable, secure attachment: 5-inch (125 mm) hook-and-loop sanding discs with a high-strength cloth backing and reinforced base provide stable performance, tear resistance, and safe operation on power sanders. 8-hole dust pattern for effective extraction: The 8-hole design aligns with standard 5-inch random orbital and finishing sanders to help remove dust and maintain a clear abrasive surface for longer life. Multi-grit set for complete sanding workflows: Includes seven grits—40, 60, 80, 120, 180, 240, 320—covering tasks from aggressive material removal to fine finishing. Higher numbers equal finer abrasives. Compatibility and function Designed for 5-inch (125 mm) orbital and random-orbit sanders, as well as compatible hand sanding machines that accept 8-hole hook-and-loop discs. Suitable for work on both wood and metal surfaces for sanding, polishing, and finishing tasks. Practical use scenarios Furniture restoration: Use coarse grits (40–80) to remove old finishes or level repaired areas, then progress to 120–320 for smoothing and preparing the surface for stain or varnish. Metal surface prep and rust removal: Aggressive grits (40–60) remove rust and paint; follow with finer grits to blend and prepare for primer or paint. Between-coat sanding and fine finishing: Use 180–320 grits to lightly sand between paint or clear coats for a smooth, professional-looking finish. Key specifications Abrasive: Aluminum oxide Coating: Open coat with stearate treatment Backing: High-strength cloth with hook-and-loop attachment Size: 5-inch (125 mm) diameter Hole pattern: 8 holes Included grits: 40 / 60 / 80 / 120 / 180 / 240 / 320 Usage tips Progress through grits from low to high for best results and even surface preparation. Use proper dust extraction with the 8-hole pattern to extend abrasive life and maintain a cleaner workspace. Replace discs when the cutting action slows or the abrasive surface becomes clogged despite the stearate treatment. This sanding disc set is built to deliver reliable cutting power, cleaner finishes, and compatibility with standard 5-inch, 8-hole orbital sanders for woodworking and metalworking projects.
