The Vevor circular saw blade sharpener is designed to restore dull and worn circular saw blades for sharper, more precise cutting. Its 370W motor runs at 3590 RPM and works with a 5" grinding wheel for efficient sharpening performance. A built-in water tank helps cool the grinding wheel during operation to reduce heat-related damage and improve blade durability. It fits circular saw blades from 3.2" to 27.5" in diameter and includes adjustable angle settings for flexible, accurate sharpening. The stable base, waterproof switch, and adjustable water hose support safer, smoother operation.
