Need a reliable, all-around blade for your 5-1/2 inch circular saw? This IVY Classic Ripcross blade is a good choice. It's a thin kerf blade (kerf width is 0.063 inches), which means it cuts with less friction and drag, putting less strain on your saw. It has 24 teeth made from C3 modified tungsten carbide, and they're ground in an alternate top bevel pattern. This makes it great for both ripping (cutting with the wood grain) and crosscutting (cutting across the grain) in plywood, composition board, and hard or soft woods. It has an anti-kickback design for safety and consistent chip removal. The blade body is fully hardened (Rockwell Hardness 40-43). It comes with two arbor hole sizes: 5/8-inch and 1/2-inch, so it's compatible with many saws. A solid, no-frills replacement or upgrade blade that delivers smooth, efficient cuts for general carpentry and DIY projects. If you're building shelves, cutting plywood for flooring, or doing general woodworking, this blade will handle it well.
