FLEX FA302006 5-inch 40 Grit SightMAX Flap Disc, Type 29

Clearly see the surface you are grinding, stripping, or shaping with the FLEX 5” SIGHTMAX™ 40 Grit Flap Disc. This 40-grit flap disc improves the working experience with its innovative segmented design that delivers transparent line of sight to the work surface while grinding for reduced over-abrasion and maximum efficiency. Along with its segmented design, a special coating reduces heat buildup on the disc compared to traditional flap discs for increased performance and longer life. SIGHTMAX™ flap discs utilize a high-quality zirconium abrasive grain for quick stock removal, and their iron- and sulfur-free construction reduces oxidizable particles left behind on finished surfaces to help prevent rust from forming. A disc coating slows moisture exposure for extended disc life. The conical 10-degree flap arrangement improves grinding ergonomics for improved tool handling.
