Merryland Cut Off Wheel 4.5" metal cutting disc 🛠️

This ultra-thin cut off wheel for a 4.5 inch angle grinder delivers fast, precise metal cutting while keeping material loss to a minimum. It is intended for users who need a consistent, long-lasting disc for cutting iron, stainless steel, sheet metal and steel tube, and it helps speed up workshop and renovation tasks with stable performance.

Key Points

The disc features a refined white corundum abrasive bonded with German phenolic resin, which the manufacturer reports improves cutting life and smoothness. Built with two layers of reinforced fiberglass mesh, the wheel aims to resist flexing and maintain stability under load. For everyday metalworking it offers a balance between thin cutting width and safety. ⚙️

This pack contains 25 identical discs, so there is a ready supply for repeated jobs without stopping to change wheels frequently. Consider that the thin 0.045 inch thickness reduces material removal but may wear faster than thicker cutting wheels under heavy continuous use. 🔧

Usage Recommendations

Use the wheel on an angle grinder or cutting machine with a 4.5 inch arbor and a 7/8 inch mounting hole. Allow the grinder to reach operating speed before starting the cut and use steady, even pressure to avoid overheating the disc. For safety, always follow the grinder and wheel safety instructions and use appropriate protective equipment such as eye protection and gloves.

This wheel works well for quick cross-cuts in sheet metal and for trimming welds where a narrow kerf is preferred to reduce grinding afterward. It may not be the best option when high stock removal is needed or when cutting very thick plate repeatedly, because the ultra thin profile is optimized for precision rather than heavy-duty longevity.
