• Best For: Tradespeople who want a mid-grade 4-1/2-inch disc for removing thinner paint and urethane coatings along concrete edges.
• Highlight: 24 grit is the third step in the four-grade 4-1/2-inch range, between 16 and 36.
• Expert Note: Run it after an 8 or 16 grit pass on stubborn buildup, or alone on lighter coatings, always within the 8,500 RPM rating.
