These depressed center grinding discs are sold in packs of fifty, built for aggressive cutting through steel, stainless, cast iron, and sheet metal. They slide easily into tight spots with cordless or corded angle grinders to deliver clean, fast cuts without dragging power.

✅ Premium aluminum oxide blend cuts fast and resists wear over fifty cycles

✅ Thin kerf design removes less material and keeps your tool running cool

✅ Double layer fiberglass reinforcement prevents shattering during heavy use

✅ Fully optimized hand held geometry delivers straight cuts in narrow gaps

💡 Why are depressed center profiles preferred over reinforced flat wheels for high RPM metal cutting?

This lowered profile clears obstacles near the work edge, making it handy for threading bolts or cutting flush to structural beams without guard interference.

- Thinner disk body drops radial load so motors run cooler under heavy feed pressure

- Coarse grain matrix sheds swarf faster than standard ceramic blends on hard alloys

- Dual fiber weave matrix distributes torque evenly to eliminate sudden panel fractures
